All models are delivered:

��In a basic version without light curtain, ��Equipped with a “A”, “B” or “TF800”-type back gauge � In option: - light curtain, which is used as front protection and as an operation

cycle control device or

- a laser beam used as front protection only. Note : In this manual, “tons” is very often used instead of international measurement unit

“kN”. We remind you that 9.81 kN is equivalent to one ton.

1 x is added to specify the level of equipment provided on your machine (T, E, P).

1.2. PRINCIPLE This hydraulic press brake is load/unload manually. HF hydraulic press brakes are down stroking machines equipped with a numerical controller for the control and adjustment of all bending parameters. These press brakes are equipped with a central reaction lower beam to ensure bending quality. An electrohydraulic servosystem controls the travel and ensures that the Upper Beam (UB) remains perfectly parallel to the Lower Beam (LB). These machines can be equipped with a variety of options (back gauge, front gauge, etc.), all Amada range of tools, and other traditional tools, as well as a range of accessories. (Contact our Regional Sales Representative to discuss your specific requirements.)

For items, heavier than 25 kg, a handling device must be provided for the operator. This device is not included in the Amada supply (see § 5.5).

REVIEW OF THE CONVENTIONAL DESIGN OF PRESS BRAKES Traditional press brakes with an operating upper beam exhibit an elastic deformation during bending in opposite directions on each beam due to the reactions of the part under the thrust of the jacks located at the ends. These deformations are detectable by slightly less penetration of the punch in the die in the centre than at the ends (Fig. 1.2).


AMADA SYSTEM

The lower beam (A) is assembled between two lateral cheeks (B and B') welded to the flanges through two largely dimensioned pins positioned on both ends of the machine’s central axis (Fig. 1.3) or (Fig. 1.3’). When bending, reaction forces tend to deform the lower beam in the same direction and parallel to the upper beam. (Fig. 1.4). ADVANTAGES

Because the small but inevitable elastic deformation of the two beams occurs in the same direction and has the same value, the punch has constant penetration in the die over the entire bending length, thus ensuring a perfect angle. The small deformation of the beams does not affect the linearity of the bend because the stress induced in the worksheet remains well within the elastic region. Up to 220 tons

GB

WARNING FOR HIGH SPEED OPERATION The safety of the operator during approach speed is given by the Light Guard. This should be muted at the sequence point when the machine changes to bending speed and should give an operating gap of no more than 6mm. If special double action tooling is used such as HemmingTools and the gap between any part of the tooling is greater than 6mm, the bending speed should be set at 10mm/sec or less.

F

AVERTISSEMENT POUR L’UTILISATION EN GRANDE VITESSE La protection de l’opérateur est assurée par le rideau lumineux pendant la phase d’approche à grande vitesse. Le rideau doit être inhibé au point de mute (au moment où la machine arrive à sa vitesse de travail) et quand la distance entre la tôle et l’extrémité de contre vé n’est pas supérieure à 6 mm. Si les outils spécifiques sont utilisés (outil superposé à écraser) et que l’espace entre les parties des outils est supérieur à 6 mm, la vitesse de travail doit être réglée à 10 mm/s ou moins.

D

WARNUNG BEIM BETREIBEN VON HIGH SPEED PRESSEN Die Sicherheit des Bedieners wird während der Zustellbewegung durch einen Lichtvorhang gewährt. Dieser wird am Umschaltpunkt ausgeschaltet, wenn die Maschine in die Arbeitsgeschwindigkeit wechselt und kein größerer Spalt zwischen Stempel und Matrize als 6 mm ist. Wenn besondere Doppelfunktionswerkzeuge wie z.B. Zudrückwerkzeuge benutzt werden under Spalt zwischen Stempel und Matrize größer als 6 mm ist, muß die Arbeitsgeschwindigkeit auf weniger als 10 mm/sec gesetzt werden.

I

AVVERTENZA PER L’IMPIEGO AD ALTA VELOCITÀ Durante la discesa veloce di avvicinamento, la sicurezza dell’operatore è garantita della barriere ottiche. Queste vengono escluse quando si raggiunge il punto di cambio velocità (la discesa rallenta alla velocità di piega): in tale condizione la distanza tra lamiera e punzone non deve superare i 6 mm. Se si utilizzano stampi speciali (piega e schiaccia), in cui la corsa è superiore a 6 mm, occorre impostare una velocità di lavoro non superiore a 10 mm/s.


2.2. PREPARING THE SITE The press brake must be installed on a stable, rigid floor.

A concrete slab 120 to 150 mm thick with a flat surface (maximum tolerance 2 mm per metre) must be laid in the work area. Please contact our technical department for the installation requirements.

HF press brakes are manufactured as welded box structures with a low centre of gravity. Anchoring them to the floor is therefore optional. The press brake must be accessible from all four sides:

- At the rear, provide a clearance of approximately 1 metre to allow various maintenance operations and backgauge adjustment to be performed.

- Allow a clearance slightly greater than the maximum bending length of the machine on at

least one of the two sides. The purpose of this is to allow worksheets that are at least as long as the press brake to be unloaded from the side.

- Provide sufficient clearance so that the electric cabinet door can be opened freely for

various maintenance work.

Figure 2.3 * With NC type : “OPERATEUR 2000” and “AMNC”.


2.4. RECEPTION & HANDLING 2.4.1. LIFTING Before the vehicle arrives, it is customer’s responsibility to provide a crane with sufficient capacity to unload the press brake from the vehicle and ensure that the access doors are sufficiently tall and wide to receive the machine, or its case (in case of sea worthy packing). To handle the press brake, use the two sling holes located towards the front on the upper part of the side frames (see fig. 2.4).

CAUTION: Lifting forces should only be applied to the sling points provided for this purpose. Never apply force to the underside of the beams, electrical cabinets, covers, etc.

For all machine handling operations, observe the following recommendations:

��Attach the lifting beam directly, with a load per strand, not exceeding the maximum allowable load.

��Lift and set down the machine gently, avoiding any side impact on the

machine, or any impact on lowering it to the floor.

��Only press on the frame or its packaging to direct the machine during handling; never press on the beams, electrical cabinets, covers or guides.

CAUTION: When a press brake has been crated for sea transport, handling it and removing it from the crate are tricky operations. We strongly advise you to seek professional assistance. For information on this point, do not hesitate to contact Amada. The instructions in this section are given for information only, and do not engage the responsibility of Amada.

2.5. ELECTRICAL CONNECTIONS Correct operation of an electrical system depends on the quality of its power supply; it must be stable and free of interference. The installation must be designed and built in accordance with the local regulatory requirements in force. 2.5.1. GENERAL CHARACTERISTICS OF THE MAINS SUPPLY - Power supply: Three-phase (according to mains). ±10% in steady-state, ±20% in transient (20 ms). - Pulse mode: 50% of rated value, maximum duration 5 ms - Harmonics: Maximum 5% - Frequency: 50 or 60 Hz (according to mains). - Electrical power supply line: Special supply line for the EXCLUSIVE use of the system

from the main LOW VOLTAGE panel. The entire system is powered by a single three-phase + earth cable.

2.5.2. EARTH Any equipment without double insulation requires an earthing connection. This is also important for operation and leak-off to the ground of spurious interference. The earthing conductor must have a sufficient cross-section. It must be connected to the terminal board of the power supply panel. Like the electrical installation, this earthing connection must be periodically checked by an approved organisation. The resistance of the earthing connection measured must comply with the applicable laws and standards. The green/yellow earthing conductor is exclusively reserved for the system. It is directly connected to the earthing terminal.


2.5.3. MAINS-RELATED AND ENVIRONMENT-RELATED INTERFERENCE

CAUTION: Never solder or weld a component to the machine using any process whatsoever. This could damage the mechanical, electrical, and electronic components.

Certain electronic components may be subjected to abnormal or excessive voltages or currents liable to cause their destruction. The installation of adapter components without a galvanic connection to the mains (voltage stabiliser, inverter, converter unit, transformer, isolating transformer, etc.) may need to be considered. If necessary, the quality of the electrical power supply should be checked by an approved organisation, and an analysis of the results should determine the type of equipment required. The following types of interference can be considered as a disturbance to any electronic system: • Electrostatic Discharge Electrostatic discharge is particularly critical where the ambient relative humidity is low. It is not unusual for a person or group of people on the move to generate discharges amounting to several thousand volts when touching a door handle or metal frame. It may be necessary to install antistatic equipment. The machine has passed tests to European Standard EN 61000.4.2 concerning immunity to electrostatic discharge. • Mains Transients Transients are spurious pulses propagating along mains conductors which may affect system operation. They may be from an internal source, e.g. welding unit, or any other machine generating mains interference, or they may be from an external source, e.g. stormy weather, neighbouring factory, etc. The machine has passed tests to European Standard EN 61000.4.4 concerning immunity to fast transients. • Stormy Weather The charges that accumulate during a storm cause transients in electrical lines or connecting cables. Do not use excessively long overhead lines. • Magnetic Fields A variable magnetic field causes induction in circuit loops—a major source of interference voltage. Cathode ray tubes are sensitive to magnetic fields, and display this sensitivity by a change in image chromatics or geometry. This is why they are equipped with protective shielding.


• Medium- or High-Frequency Electromagnetic Radiation This type of interference can cause many problems in systems (operational amplifiers, computer memory, etc.). In general, the extent of the disturbance depends on the duration and intensity of the radiation. It may be caused by nearby radar systems or radio transmitters (military, police, FM radio station, etc.), or even by poorly filtered cathode ray tubes. Although the machine has passed tests to European Standards EN 50140 and 50141, for optimum operation of your machine, install the press brake in an environment that is free of the disturbances mentioned above (reference values : field 0.2 to 0.5 V/m, frequency band 10 kHz to 1 GHz).


2.5.4. POWER SUPPLY CABLE CHARACTERISTICS The characteristics of the power supply cable must comply with the safety regulations in force. Cable cross-sections (mm²) are given for a line less than 20 m long for the whole models in the product range, and for a 400-V power supply. For any other specifications, refer to standard.

Example : EN 60204-1 (IEC 204-1).

See electric diagram on how to pass the incomming power supply cable through the electric cabinet. The power supply cable should never be passed through the “C” frame in front of the electrical cabinet. The machine is equipped with its own current protection devices, but the supply line must be equipped with a cut-off device to protect it from short circuits and over currents (not included in Amada supplies). The cable and its mechanical protection devices, if any (cable troughs, raceways, sheaths, etc.) must have a protection rating according to the mechanical risks and corrosive agents to which they are liable to be exposed (not included in Amada supplies). The routing of cables and their protective equipment must not create any hazard (falling) to operators or maintenance personnel. Connect the three power supply wires directly to the corresponding terminals of the circuit breaker, with the earth wire (green/yellow) directly on the earth terminal intended for this purpose. The circuit breaker is designed to accommodate up to three padlocks. We recommend that you install a padlock immediately, to prevent the system being switched on until the AMADA technician arrives to put your machine into operation.

CAUTION: All work on electrical installations must be performed by qualified personnel trained for the purpose in order to prevent any accidents or damage to equipment.


2.6. WORKSTATION LIGHTING

CAUTION: Ensure that the workstation has sufficient lighting for the parts to be worked on.


2.7. SAFETY PRECAUTIONS 2.7.1. GENERAL POINTS During machine installation, operation, and maintenance, apply all necessary safety measures, and the following in particular : • Do not adjust or service the machine until you have read the manual. • All electrical work must be performed by a qualified electrician, to avoid all equipment

damage or physical injury. • Never place your hands between tools for any reason. • Do not modify the control circuits or any component of the machine. • Never use the machine with any of its safety devices removed or disabled. • Do not enter the safety zone or hazardous area protected by safety device. • Inspect the machine daily before starting work, ensuring that :

- All protective devices are in place. - The free space between the tools is not obstructed. - The access area for the various devices is clear. - The floor around the machine is free of grease, oil, and water.

• Never wear a tie, scarf, or loose clothing when adjusting or operating a press brake.


• Make it a rule that a single qualified, trained operator performs machine adjustments. When

working on large parts, the operator may be helped by an assistant operator whose sole task is to help handle the blank. The assistant must have an equivalent control panel (electric footswitch) to authorise the operator to initiate the cycle.

• Before machine inspection or maintenance, switch off the main electrical isolating switch

unless power is required for the procedure concerned. In such cases, only personnel with the appropriate training are authorised to carry out the procedure.

• Wear protective gloves whenever possible. • On rare occasions when the user bends parts whose overall size exceeds the length of the

machine's beam, protective measures must be implemented to prevent injury to other persons. If this type of job is performed frequently, additional protective measures must be permanently installed, in association with the machine's control circuit where appropriate.

CAUTION : Use of the machine by unqualified, untrained personnel engages the employer's liability (Labour Law L 233-5-1) as well as the operator's liability (Labour Law L 230-3). The mentioned labour laws applies to France only.


Important note relating to Personal Protective Equipments (PPE)

The so-called “Personal Protective Equipments” (PPE) are not included in Amada supplies. You will find below as informative examples the type of Personal Protective Equipments that one will require on our machines:

• gloves, • helmets, • ear guards, • goggles, • goggles to protect against laser radiations, • safety shoes, • etc.

It is the responsibility of the user of the PPE to ensure that the equipment he /she is using fully complies with the European Directive 89/686/CE. This verification should be carried out with in the guide-lines of the European Directive 89/656/CE. The said directive is transposed in the French Labour Law “Code de Travail” and applies to the employer (Act 93-41 dated 11/01/1993 and article R233-1 and R233-83-3) i.e. all French employers are obliged to:

• ensure that the appropriate PPE are selected relating the risks involved, • supply the appropriate PPE to the employee concerned, • ensure that the employee is using them efficiently, • ensure their compliance with the regulation, • inform people who are responsible for the implementation (work shop manager,

foremen, etc.), • ensure the PPE are in perfect working condition and periodic maintenance is carried

out, • inform users which potential risks are protected by the use of PPE, • train and lead users in the regular use of PPE.

In any case, the PPE which are in compliance (self certified or certified by a notified body) should have: A CE marking (visible and affixed firmly) and showing:

��the name or the trade mark of the manufacturer, ��identified either by commercial name or the reference of the PPE, ��the size, if implies, ��the expiry date, if implies,

and should be accompanied by the information leaflet and user manual along with the CE declaration stating that it complies fully with the European Directive 89/686/CE.


CAUTION: The machine may not be used in an explosive environment.

The operation and maintenance of this machine are strictly reserved to professional, qualified personnel. For this purpose, Amada Metrecs provides training for operators, setters, programmers, and maintenance technicians on its own premises or on the customer site.

• Fire Prevention & Emission of Harmful Substances HF press brakes present a low risk of fire or emission of harmful substances. We

recommend that you keep fire extinguishers for electrical equipment and oil near the machine.

• Ensure that the strength and length of the tools used are compatible with the pressure setting

(see Para. 2.9, Machine characteristics and Para. 5.5 tool installation). Press brakes are supplied with the following safety equipment :

- A set of two footswitches (closing/opening), - Cycle selector key switch, - Automatically controlled side and rear guards, - Self-controlled electro hydraulic circuit.

Options:

1) Light guard to protect the front area.

o Another control unit for assistant operator, including 2 footswitches (opening/closing).

o A laser beam, to protect the front area.


The press brakes listed in Appendix IV of Machine Directive 98/37/CE have fulfilled the requirements of the Type Testing procedure, as certified by NORISKO, a notified body registered with the European Community by the French Ministry of Labour. Each machine delivered in European Union is therefore accompanied by a declaration of conformity like the following example :


2.7.2. REGULAR INSPECTION AND SAFETY POLICY

NOTE The below-explained items are valid for France only. Any other country should refer to its current and domestic regulation.

��Article R233.11 of the labour law and the Act dated 5 March 1993, modified by the

Act dated 4 June 1993, require preventive maintenance to be performed on a quarterly basis. The purpose of this regular servicing is to detect any fault liable to cause an accident in advance, so that such faults can be rectified.

The results of this service call are recorded in a safety register opened by the Site Manager and made available to the Health and Safety Executive and the CHSCT (if any) at all times. This measure applies to any manual-feed press working on cold rolled metals. The servicing must be performed under the responsibility of the Site Manager by qualified persons trained in risk prevention. A list of such personnel is made available to the Health and Safety Executive. ��The so-called Bulletin Officiel (Official Information Note) - # 2002/22 dated 5th

December 2002 and issued by the Labour Office – points out which engagements every head of company is compelled to (implementation scheduled on the 1st September 2003).

For all utilisation of press-brake, the user is obliged of : - Use the protection devices in order to secure the front faces on press-brakes. - Arrange the working stations through the installation of devices suited to the parts to be

bent : part-holder , adjustable table. - Think out of a convenient working organization due to secure the passing-through of

batches of new parts. - As for safety instructions, provide the proper training to operators and particularly to non-

experienced benders or temporary workers.


2.7.3. ARRANGEMENT OF WORKSTATIONS There are five separate workstations for the following functions:

- Electrical cabinet “location 1” - Adjusting the backgauge “location 2” - Programming “location 3*” - Production “location 4” - Assistant Operator “location 5” in the event of production being carried out by two

operators (Caution : provide the assistant operator with similar equipment as for the main operator : see § 2.7.1).

2.7.5. RULES FOR SAFE OPERATION � Release the part to be bent as soon as it is gripped between the tools (Fig. 2.12). � Install or remove the tools in strict compliance with the procedure described in the

Operator Manual (§ 5.5) and / or with the recommendations specific to your tooling (Fig. 2.13).

To avoid damage to your tooling or any accident, Amada urge you to follow strictly the procedure below :

•Every time you change a program, select adjustment mode and mute stop.

•Carryout a dry cycle (without material). •Check visually that all introduced parameters corresponds to the

tooling mounted on the machine and the mute point is 6 mm above sheet pinch point and the end of bend is correct.

•Then and only then choose the normal operating mode for the program in question.

CAUTION: Handling devices for heavy parts are not included in the basic Amada supplies. They must be installed for risk-free use in accordance with ergonomic principles.

��The dutch bending or hemming tool should be firmly secured to the lower beam (Fig. 2.19). This type of tooling shouldn’t be used on “High Speed” press brakes i.e. where working speed can reach 20 mm/s.

��Never hold the sheet by its folded edge; hold it from the sides (Fig. 2.20).


2.8. MACHINE’S OPERATING AND STORAGE CONDITIONS To ensure long life for the electronic and hydraulic components, conditions should be maintained within the following limits: Min. Max.

Ambient machine storage temp. ............................. -10°C ................................... +50°C Ambient operating temp. ......................................... +5°C ................................... +35°C Oil temp. .................................................................. +5°C ................................... +80°C Relative humidity ...................................................... 20% .................................... 75%

For temperatures below 5°C, the NC unit must remain powered to keep the components and circuit at a normal temperature. No equipment that produces swarf, dust, paint flakes, etc. must be installed in the immediate vicinity of the machine. If this is not possible, apply all possible measures to protect the press brake from all factors liable to hinder its smooth operation.

CAUTION: Amada Metrecs engineer will put your machine into operation. Please provide a supply of test sheets for this purpose. Select the material and sheet thickness you use most often. Any prior use of the machine will lead to suspension of the guarantee. Validity of the guarantee will not be restored until the installation has been inspected and, where necessary, the machine has been repaired at your expense. Use of the machine by unqualified, untrained personnel engages the employer's liability (Labour Law L 233-5-1) as well as the operator's liability (Labour Law L 230-3). These labour laws applies to France only.

NOTE: To gain maximum benefit from our technician's visit, remember to remove the equipment from its crates and degrease it before the technician's arrival.

If the oil temperature is below 5°C, there is a risk of the machine operating incorrectly. To prevent this, press the STOP button, and then press the opening footswitch for 5 to 10 minutes (see Para. 3.7).

3.3. CHECKING THE MAINS POWER SUPPLY As supplied, the machine is intended to run on a three-phase 400 V 50/60 Hz power supply. Any other voltage requires a transformer (not supplied). 3.4. MACHINE LEVELLING To set your machine up with the correct geometry, apply the following procedure strictly.

Because your press is designed not to be anchored to the floor, the concrete slab must be flat to within 2 mm per metre. Horizontal levelling does not require great accuracy; 1 mm per metre is sufficient. Up to 220 tons The levelling of each upright is performed using each of the two screws at the rear of the machine (Fig. 3.1). The perpendicularity reference is taken with a precision level (accurate to 0.05 mm/m) placed on a straightened rule which is in turn resting on two dowel pins in each of the uprights. Tolerances: ±0.05 mm/m per upright, and 0.05 mm/m with respect to each other. Valid for 320 and 400 tons The levelling of each upright is performed using four M30 screws at the rear of the machine (Fig. 3.1). The perpendicularity reference is taken with a precision level (accurate to 0.05 mm/m) placed on a straightened rule which is in turn resting on two dowel pins in each of the uprights. Tolerances: ±0.05 mm/m per upright, and 0.05 mm/m with respect to each other.

IMPORTANT NOTE

THE MACHINE MUST NOT REST ON SUPPORTS OTHER THAN THOSE DEFINED IN FIG. 2.4 (CHAPTER 2) OF THIS MANUAL. For specific installation conditions, contact Amada’s Technical Department.


3.5. PUTTING THE MACHINE INTO OPERATION START-UP .SEE CHAPTER 6.1. DIRECTION OF ROTATION � Check the direction of rotation of the hydraulic unit. To do this:

- Start the pump by turning the selector to the right. - Compare the direction of rotation of the motor blades to the red arrow on the motor

casing.

- If the direction does not match, stop the pump rotation by turning the selector

to Position 0. - After switching off the main circuit breaker of the machine swap 2 phases at the supply

terminals.


3.6. OVERALL CHECK � Check the mountings of all covers and casings. � Check that no foreign body is present on the ball screws of the back gauge axes or the guide

rails. � Check that the cables are secure in the stuffing boxes (electrical power supply cable), and

check the cable grip at the bottom of the electrical cabinet (footswitch). In the electrical cabinet, check that the earthing wires are properly connected to the terminal blocks.

� Check that the limit switches are operating correctly. � Check that no cover is liable to be caught during movement. � Check all the indicator lights and check that all machine stops and key switches are

operating correctly. � Check that the light guard (if any) is operating correctly. Refer to the specific Appendix

concerning the light guard. WARM-UP In the event of a low ambient temperature, it may be necessary to warm up the hydraulic circuit. To do the warm up, apply power to the machine, start up the hydraulic unit, and lets climb up the temperature for 5 to 10 minutes.

4.1. MECHANICAL STRUCTURE Up to 220 tons Comprising : (Fig. 4.1) 1) A welded frame, including:

- Two uprights (Items 1 and 1’) - Two groundplates (Items 2 and 2’) - One connecting beam (Item 3) - 2 cheeks on the lower beam (Items 4 and 4’)

2) Removable mechanical components:

- One moving upper beam (Item 5) - One fixed lower beam (Item 6)

Valid for 320 and 400 tons Comprising: (Fig. 4.1’)

- Two uprights (Items 1 and 1’) - Two groundplates (Items 2 and 2’) - One connecting beam (Item 3)

- 2 cheeks on the lower beam (Items 4 and 4’) - One moving upper beam (Item 5)

- One fixed lower beam (Item 6)


4.2. MECHANICAL CONNECTIONS 1) The upper beam is supported by the uprights via the two hydraulic cylinders. Four track-

eccentric roller assemblies guide the upper beam very well, and are used to provide axial adjustment.

A linearity device with a push-pull system located at the rear of the upper beam ensures that this beam is perfectly linear, resulting in straight bends.

2) There are two hydraulic cylinders. Their purpose is to transmit the required bending force

to the upper beam, and to provide lateral guidance. The NC unit synchronises them via very high precision linear scales to obtain parallelism and location accuracy to within 1/100e mm.

The piston rods press the upper beam via spherical supports. This linkage ensures that the piston is perfectly aligned in the cylinder by maintaining the reaction due to the thrust effects in the axis of the uprights.

3) The lower beam is mounted in between the two fixed side plates. These side plates are

welded for machines up to 220 tons and assembled for 320 and 400 tons to the machine side frames. The lower beam is supported by two large steel shafts located at each side of the press brake axis. Up to 220 tons


Valid for 320 and 400 tons

During bending, the reactive forces deform the plate in parallel with the upper beam. Consequently, the deflection of the two beams is of the same value, thereby ensuring that the punch penetration into the die remains constant throughout its entire length, ensuring accurate bending.

4) The reference position of the moving beam is taken completely independently of the side

frame to avoid introducing any error resulting from side frame deflection. A uniquely designed external “C” frame that remains rigid under all bending conditions insures that accurate ram positioning is maintained even with side frame deflection.


4.3. ELECTRONIC STROKE CONTROL AND PARALLELISM BALANCING SYSTEM The clever design of the catches which are located exactly in the bending axis of the fixed and mobile beams allows the reference positions of the mobile beam to be read accurately, independently of the slightest deformation of the frame. The great rigidity of the strong external “C” frames and the securing of the linear glass scales provide a reading to 1/100th of a millimetre, irrespective of the loads applied to the frame and the beams. Extremely Accurate Incremental Measurement The linear scale is made of glass and has a grid (40-µ steps). It represents the travel of the upper beam with positioning of ±0.01 mm between the punch and the die.

4.3.1. ELIMINATING SOURCES OF ERROR Under normal conditions of press brake use, several parameters have a direct effect on the accuracy of the bending angle. � Oil viscosity (temperature). � Operating pressure (working force). � Position of the parts (if off-centre, this leads to unequal forces on the uprights). Because it is virtually impossible to have full control over all these factors, risks of error are introduced, which are liable to affect the bending quality. A new technique allows Amada to eliminate these risks completely. 4.3.2. PROPORTIONAL VALVE TECHNIQUE FOR CONTINUOUS RELIABILITY This extremely sophisticated electronic regulating technique guarantees perfect balancing of the parallelism by making it independent of factors liable to alter it. Two incremental linear sensors Y1 and Y2 are mounted at each end of the upper beam. The sensors are directly connected to the electronics of the NC controller for Machine. This controls the oil flow to each cylinder via proportional valves B and B’. When the upper beam is lowered, the sensors continuously record the changing positions very accurately. These signals are immediately sent to the NC controller, which checks the respective values. The slightest difference between the data supplied by the sensors automatically triggers oil level compensation and pressure balancing.


4.3.3. PRECISE CENTRING OF THE BEAMS The upper beam is guided by a set of four pairs of generously sized roller guide assemblies (1) running on hardened ground steel surfaces, securely fastened to the machine uprights. The maximum spread between the upper and lower roller guide assemblies (E max) ensures precise alignment and centring of the beams, with perfect rigidity. Reference cylinder D provides lateral positioning.

4.5. PRESS BRAKE OPERATING LIMITS IN OFF-CENTRE WORK The further a point is from the centre of the machine, the smaller the available resultant force at that point. This information is taken into account by the NC controller, which calculates the force required according to the user-programmed part position. 4.6. PRESSURE GAUGE A pressure gauge is placed on the outer side of the lateral left cover. By comparing the displayed pressure (in bars) to the maximum pressure given in the machine characteristic table § 2.9 in Chapter 2, you can see if the machine is reaching its operating limits.

The NC unit lets you limit the force according to the tool (refer to limit values in tool catalogues).

5.1. GENERAL POINTS Bending consists of forming parts from flat sheets. Deformation is linear and simultaneous over the entire length of the part on a finite machine and tool, and continuous when rollers are used (infinite length). Fig. 5.1: Punch and die. Press brake.

Angular variation limited to each pair of rollers. This list of forming methods is not exhaustive. This chapter only deals with punch-and-die bending (Fig. 5.1). There are two basic bending techniques: - AIR BENDING Commonly performed because it requires relatively low bending forces. - COINING Requires forces equal to three to five times those of air bending. Allows the inside radius to be coined, which practically eliminates the elasticity of the material.

t = thickness

Die = 8 to 10 t.


5.2. AIR BENDING During air bending, the sheet metal retains certain amounts of elasticity in the plastic region. An angle more acute than the desired angle must therefore be produced to compensate for the opening due to spring back effect. The calculation made takes into account all the parameters required by air bending. Our standard air bending tools are designed accordingly. The bending chart located on the press brake electrical cabinet gives the required forces and inside radii obtained according to the other characteristics (thickness, die opening, etc.). The sheet is in contact with the tools at three points (A, B1, B2) as shown in Figure 5.8. A necessary consequence of this for bending quality is: die = 8 to 10 times the sheet thickness. (For angles ≥ 135°, preferably use a die = 10 to 12 times the sheet thickness). Sheet deformation is interrupted before it reaches its penetration limit in the die. NOTE If there is a specific requirement for bending, edge dimension, inside radius, etc., use the technique for air bending at the bottom of the die (partial coining) or coining. AIR BENDING AT BOTTOM OF DIE OR PARTIAL COINING (Fig. 5.9) In this case, the sheet penetrates to the bottom of the die and is supported by the sides, with no increase in the bending force. This type of bending is seldom used because of the inaccuracy of the results obtained. Coining should be chosen over partial coining whenever possible.


5.3. COINING This type of bending is comparable to stamping. The end of the punch penetrates the sheet at the bottom of the die, rupturing the elasticity of the sheet, which is then bent exactly to the shape of the punch.

- In practice, for a 90° bend: - Die width = 5 to 8 times the thickness. - Die angle = 90°. - Punch angle = 90°.

The state of the part is similar to that shown in Figure 5.9 for partial coining, except that the forces at the end of bending are 3 to 5 times the air bending forces, which causes the coining of the sheet. NOTE The choice of punch radius is very important, because it determines the inside radius of the bend (stamping of the punch in the sheet). Coining can be performed with a punch and die of the same angular value only. Very high bending forces must be applied; these may reach values from 3 to 5 times those shown on the air bending chart.

CAUTION: Because coining involves very high forces, take great care to check the strength of your tools. Never exceed the applicable force limits. These values depend on the type of tool, and should normally be shown in tool catalogues (Para. 5.5).


5.4. LIST OF STANDARD TOOLS

(Refer to “Amada’s Press Brake Tooling” catalogue) Qualitative characteristics common to the whole range:

� Easy to store. � Easy for one person to handle. � Hardened working surfaces. � Standardised mounting systems. � Special profiles suited to different sheet

thicknesses. � Wide range of profiles suited to all

applications. � Special custom-designed profiles for

sufficiently large production runs. � Rabbeting in the heel preventing the tool from

dropping when tool clamp plates are unfastened.

Our tools have two standard lengths: 835 mm and 415 mm.

Certain tools are sectionalised in pre-determined dimensions. For details regarding these tools, please refer to “Amada’s Press Brake Tooling” catalogue. These sectionalised tools allow four-sided bending for items such as boxes, drawers, shelves, etc.


CAUTION: For any issues involving tools or bending materials other than sheet metals (list of range, profile, linear strength, etc.), please contact AMADA. A tooling specialist will analyse your specific problem. A simple telephone call will make your job easier and help you to work in complete safety.

The “Amada’s Press Brake Tooling” catalogue gives you the complete list of available punches and dies. During commissioning, our technician will enter a list of all your tools in your NC unit, and will show you how to input new tools yourself. You will then have the complete list of your punches and dies stored in the NC memory. You must then identify them very carefully when using them to allow the NC unit to calculate the penetration from exact values. If for any reason the number were illegible on the tool, you could identify it by measuring the following parameters:

- Height (mm and hundredths) - Tip radius - Angle

and then identify it in the NC unit from these three values by scrolling through the list.


5.5. TOOL INSTALLATION 5.5.1. STANDARD FAST PUNCH CLAMPING SYSTEM Amada’s standard fast punch clamping system allows an easy and fast mounting of the punches. The use and possibilities are described here after:

Lateral mounting of the punch (short punch lengths)

Punch is clamped


Punch is released

Lateral extraction of the punch


The procedure remains the same for longer punch lengths:

Lateral mounting of the punch (longer punch lengths)

Punch is clamped


Punch is released



5.5.2. “AMACLIP” PUNCH CLAMPING SYSTEM To increase safety and flexibility, on top of extra-ordinary qualities of the standard fast punch clamping system, Amada put together a fast clamping system-permitting front loading and unloading of the punches. This solution reduces considerably the tool change time when it comes to frequent punch changes, at the same time remaining totally compatible with standard Amada range of tooling available in Amada’s Press Brake Tooling catalogue. All existing possibilities of the standard fast punch clamping system is conserved, e.g. stacking of the distance pieces for bending deep boxes etc. The use of “AMACLIP” punch clamping system under different condition is explained here after: - Short length of punches (less than 200 mm)

Front-loading of the punch

It is to be noted that it is still possible to load punch laterally (in this configuration, “AMACLIP” doesn’t offer any advantage over standard fast punch clamping system).


Punch is clamped (this operation is identical to the one used for standard fast clamping system).

Punch is released (this operation is identical to the one used for standard fast clamping system).


Front unloading of the punch by pressing the punch releasing lever to allow punch to come off from the bottom.



- Punches having lengths equal or higher than 200 mm

Front-loading of the punch



Punch is clamped (this operation is identical to the one used for standard fast clamping system).

Punch is released (this operation is identical to the one used for standard fast clamping system).

Lateral extraction of the punch (this operation is identical to the one used for standard fast clamping system).

NOTA It is mandatory to extract laterally the punch when a single length of punch is clamped by two distance pieces (even though eventually it may be possible to extract the punch from the bottom by pressing simultaneously the two central releasing levers). Because there is a risk that the punch may slip and drop during this manipulation and may cause injuries to the operator.


5.5.3. « EXPERT » CLAMPING SYSTEM – MANUAL VERSION (OPTION) To increase safety and flexibility, on top of extra-ordinary qualities of the standard fast punch clamping system, Amada put together a fast clamping system-permitting front loading and unloading of the punches, up to a 835 mm length. This solution reduces considerably the tool change time when it comes to frequent punch changes, at the same time remaining totally compatible with standard Amada range of tooling available in Amada’s Press Brake Tooling catalogue. All existing possibilities of the standard fast punch clamping system is conserved, e.g. stacking of the distance pieces for bending deep boxes, etc. The use of “EXPERT” punch clamping system under different condition is explained here after:

Lateral loading of the punch (medium-sized in the above example)

For 835 mm long punches, the lateral insertion should be carried out as follows :

NOTE The 835 mm long tool should be supported by 3 distance pieces minimum before any release by the operator.

Front loading of the punch

��


In order to make the front insertion of the punch easier, the operator may tilt it as shown below. First start with operation � then �. Also valid for short punches.

Punch is clamped

Punch is released



Front extraction of the punch

NOTE In case of the front extraction of a 835 mm long punch, a remarkable force should be applied downwards by the operator. The front extraction of the 835 mm long tools is possible, but it is not recommended because the operator may be disturbed by the important weight of the punch.


5.5.4. « EXPERT » PNEUMATIC CLAMPING SYSTEM – AUTOMATIC VERSION (OPTION) For the extraction of the punches, refer to the procedure used on a manual version. The clamping and extraction operations are carried out by a centralised control system which may be monitored by a push-button.

CAUTION: Tool installation and removal procedures must be performed by trained personnel qualified for the job. Such procedures must be performed in manual setting / adjustment cycle, which enables beam movement at low speed. The maximum tool load in tons / meter must always be taken into consideration.

5.5.5. TOOLING INSTALLATION PROCEDURE Tool Installation (Fig. 5.10 and 5.11) 1) Place the lower part of the tool into position, depending upon the tools being used i.e.: - Spacer, - Single V die with die holder, - Two V die with die holder, which are slid onto the table of the lower beam. 2) Secure using the front clamp plates as shown in the diagram (Fig. 5.10). The rear clamp plates must never be loosened because they provide the reference surface for

tool alignment.

Note: In the event that a 2 V die requires alignment, ensure the locking screws (Hm8) that attach the die to the die holder are loosened (13-mm flat spanner).

3) Select a program on the NC unit. 4) Go into sheet pinch point TEACH mode (see Appendix A: Operator’s Programming

Manual § 1.12 Teaching mode). The use of this mode guarantees machine operation at minimum pressure.

5) Enter the stacking value Y consisting of: lower tool height + punch height + 3 mm

(Fig. 5.11). 6) Depress the closing footswitch and rotate the remote hand wheel in a clockwise direction1

or press the hand wheel buttons on the keypad2 until the S.P.P. (Sheet Pinch Point) value corresponding to the y value is obtained.

1 Machine equipped with “OPERATEUR 2000” NC 2 Machine equipped with « CD2000 » NC


7) Release the Closing footswitch. 8) Press the machine emergency stop button. 9) Introduce punch tip into the V groove of the die and slide the punch lengths into the dies,

and clamp. 10) Reset the machine emergency stop. 11) Press the green START button on the NC unit. 12) Depress the Closing footswitch. 13) Turn the remote hand wheel on the control clockwise until the displayed value of the sheet

pinch point ends1 or use push buttons on the NC which command the closing of the upper beam until change in the displayed value of the sheet pinch point ends2.

14) If using dies that require alignment using a punch (e.g. 2V dies), tighten the screws (Hm8)

using the 13-mm flat spanner whilst holding down the Closing footswitch. 15) Press the Opening footswitch to raise the upper beam. 16) Set the pressure to a value required to perform the bending operation but do not exceed

the maximum value for the tooling being used. The machine is now operational. Special Case 1) Sectionalised tools

When sectionalised tools are used, whether dies or punches, there is always a risk that the tool settling force may exceed the tool strength. Each tool type has its own strength, which is given in the sales tool catalogues as well as being marked on each tool.

Example: Sectionalised 4 mm gooseneck punch: - Maximum load withstood by this tool: 11 T/M i.e. 110 kN - Total length of sectionalised tool: 800 mm In this case, the maximum force that this tool can withstand is: - Max. load withstood by tool (kN) x total tool length/1000

110 x 800/1000 = 88 kN. If you exceed this value it will create “DANGER”.

1 Machine equipped with “OPERATEUR 2000” NC 2 Machine equipped with « CD2000 » NC


Minimum force values for each type of machine: see Chap. 2 § 2.9. The following formula is used to calculate the minimum length required to withstand the minimum force applied by the machine: Minimum force of machine (kN) x 1000 / Maximum load withstood by tool (kN). Example: - Machine: HF 170.4 (170 T, 4 m) - Minimum force applied by this machine: 210 kN - Minimum tool length: 210 x 1000 /110 = 1909,09 rounded up to 1910 mm (due to tool

sections) In this example, a 800 mm sectionalised tool cannot be used to set the tools as the minimum tool length required is greater than 800 mm.

- All press brakes are designed to take a maximum authorised tool length. This value is given in Para. 2.9, Chap. 2 (Table Length), and reminded at the bottom of the Table under Number of Tools.

- Do not exceed these limits.


Note It is technically in-correct to align and set a long length of die using a short length of punch. a) When bending with one or more short lengths of punches (< 835 mm) in combination with

a long die, abide the following procedure: � Follow steps 1 to 11 of the procedure where punch length is identical to the die length. � Loosen and remove the punch(es). � Press the Opening pedal to raise the upper beam to top dead centre.

IMPORTANT NOTE Since the next strep within this procedure need the adjuster hands to be introduced between tools, safety should be ensured as much as possible if the machine is set in operating mode (manual, semi-auto, automatic, etc.).

END

The operator should return to the main menu by pressing key : FIN

and trigger the machine stop located either on the NC panel or on the lower beam and message 129 is displayed : « MACHINE STOP PRESSED ».

� Position the sectionalised punch(es) by laying them under the distance piece bearing

surfaces. b) When bending with a punch longer in length than one or more short die lengths, proceed as

follows:

Apply the procedure described in “a)”, using a full die length to centre the die & holder, and then remove this die length and replace with the required sectionalised bits.


TOOL REMOVAL PROCEDURE - Bring the tip of the punch to about 3 mm from the bottom of the die (refer to installation

procedure, Steps 1 to 7). - Loosen the punches, and slide them out via one end of the beam. - When all the punches have been removed, press the Opening footswitch to raise the upper

beam. - Remove the dies by loosening the mounting screws from the front clamp plates. The rear

mounting brackets should not be removed because they are used as a reference for tool alignment, if this can be avoided.

TOOL STORAGE - To protect the working edges of your tools, we recommend that you store them in a

specially-designed tool cabinets (Part No. F 93010) near your press brake, or lay them on wooden slats or other soft materials.

- Apply a film of oil to protect them against corrosion.

TO INSTALL AND REMOVE TOOLS IN COMPLETE SAFETY, THE OPERATOR MUST APPLY THE ABOVE SAFETY RECOMMENDATIONS, AND MUST BE EQUIPPED WITH PROTECTIVE GLOVES AND APPROVED SAFETY SHOES.

Notified Bodies have harmonised (for both men & women) the weight limit at 25 kg. Beyond this limit, personnel liable to perform such handling operations must receive appropriate training, and the items to be handled must be equipped with a handling device (special machining, tapped holes, etc.).


5.6. OPTIONS AND ACCESSORIES See Appendix E.


5.7. INSTALLATION AND ADJUSTMENT OF DISTANCE PIECES A) Purpose To allow fine adjustment of the line of tools to obtain minimum angular variance over the length of the bend under given conditions. B) Purpose of Adjustment The purpose of the adjustment is to compensate for differences in penetration between the punch and die. It is represented by the distance piece curve.

The various adjustment curves for a given machine have a similar overall appearance. The amplitude of the values varies according to: Type of material, mechanical properties (tensile strength). Length and thickness of sheet to be bent (the adjustable distance piece design enable you to use all the tools in the Amada range). Note The distance piece curve for Amada machines is factory-adjusted according to average values, and checked by the Amada technician during commissioning on the customer site.


Figure 5.12

Figure 5.13


C) Adjustment Preparation: On all distance pieces constituting the tool line. Release the adjustment wedge by loosening the screw (Item 6) (6-mm hex socket wrench). Slide the wedge, Item 9, to the bottom of the slot towards the right. Slightly tighten the screw, Item 6, and then firmly tighten the tool spacer using the two screws, Item 8 (8-mm hex socket wrench) (see Fig. 5.12). Settling the Distance Pieces Either use two identical lengths of die + punch, or use two special parts to be manufactured according to Figure 5.13. These parts are moved at the same time and systematically for the settling of each pair of distance pieces. - Set the press brake for a force of 20 tonnes (200 kN). - Settle the two end distance pieces at the same time, and then the next two, and so on. If

only one remains at the centre of the press brake, it should be settled using a force of 10 tons (100 kN).


Figure 5.14 The distance pieces are set to zero in the factory for the entire HF range except for HF 103-3 and HF 220-6 machines. Position of standard distance pieces on these machines are as follows:

Figure 5.15


Adjust dimension E using travel dial indicator: Select the lowest distance piece, i.e. the one with the smallest distance E (Fig. 5.14). Immobilise its wedge using the 6-mm (hex socket wrench screw) (Fig. 5.12). Place the travel dial indicator on the lower beam, at the centre of the distance piece, and set the pointer to zero. Adjust the other distance pieces either: - By adjusting the values given in the curves (Fig. 5.15). These are off course average

values for a given machine. - By customising these adjustments according to the operating conditions and the results to

be obtained.


5.8. PUNCHING Your machine cannot be used for punching, notching, etc. BENDING CHART This chart was drawn up for mild steel with a shearing strength of 40 to 45 daN/mm². Using the chart, you can normally find the following information if the sheet thickness e and inside bending radius ri are known:

� Force (kN) per metre of bent length f � Size of the smallest possible edge b � Opening of the die to be used, V

Recommended die openings are shown in shaded boxes.

This opening, V, is related to the thickness e of the sheet to be bent. The recommended values are as follows: For e ≤ 10 mm V = 8 e Pour e ≥ 12 mm V = 10 e

If the recommended opening cannot be used (small edge cannot be created, tool not available, insufficient force, etc.), use a die with an opening that is near the recommended value, shown in the light boxes of the chart. This chart is also valid for the bending of other materials (e.g. stainless steel or aluminium); simply apply a correction factor to the values according to the ratio of the mechanical strengths.

Example: If the chart, based on 40 daN/ mm² steel, gives a force of 500 kN for a given bend, the force is 250 kN for the same bend on a 20 daN/mm² aluminium sheet. BENDING CHART LEGEND PLATE

Bending with 2 operators NOTE : Unless a second control equipment similar to that used for the main operator is added to our machines, they cannot be run by more than one operator. An optional second operator control station may be supplied for the second operator. Nevertheless, due to the occasional use of such a configuration, following should be observed for safe use of this option :

• Select « 2 operators » mode using key selector.

• The operator or fitter should remove the key and keep it by himself so as to prevent anyone else changing the keyswitch position while operators are bending parts.

• Test correct operation of the option before bending operation using following procedure : ��Select the adjustment cycle (Safety speed). ��Press opening footswitch at operator 1 control stations, the beam opens. ��Press opening footswitch at operator 2 control stand, the beam opens. ��Press closing footswitch at operator 1 control stations, no beam movement should occur. ��Press closing footswitch at operator 2 control stations, no beam movement should occur. ��Press both closing footswitches, the beam should close.

NOTE For the machines equipped with the safety programmable logic controller, the footswitches should be operated within 4 seconds. Should it take longer, both operators should have to release the footswitch before a new cycle can be initiated.

NOTA

Same procedure whenever using the two-hand control.

Bending with one operator and 2 control stations (multi staging or multiple bending) Machines equipped with Safety PLC unit allows a single operator to use two independent control stations.

• Select « one operator » mode using key selector switch.

• Program auxiliary function « F » (see Appendix A) corresponding to the workstation you intend to use in each bend.

For instance it is possible to program footswitch 1 in bends 1, 2, 4 and 5 and then footswitch 2 in bends 3, 6 and 7. If wrong footswitch is pressed, no motion will occur ; an alarm will be generated and displayed on the CNC screen.


Bending at the extremity of the beam In some cases for bending specific parts, working on one side of the machine may be necessary (box, cone, etc.). Since bending at the end of the beam is rather rare, operating safely implies the following actions :

• Select the « adjustment » mode with

key selector switch, in this case, beam will only move in safety speed (≤ 10 mm/s for out of US market machines and ≤ 20 mm/s for US market machines).

• Press green reset push button, the light will come on confirming the new mode of operation.

• Open only the required side gate. Opening both of them will generate a machine stop, because operator’s visibility is poor for the far end.

NOTE Only trained and qualified operators should be entitled to work in this way, taking into full consideration the backgauge movements while bending such parts.

• When the machine is equipped with the optional second operator control panel (footswitch

control), it is possible to operate the machine with both side gates open only if machine is operated by two operators. In that case, turn the 2nd operator work switch to two operator position.

Recommendations specified in section « Bending with 2 operators » are totally applicable and should be observed in this case.

NOTE In this specific case, both foot switches should be pressed within a maximum of 2 seconds. Otherwise, both operators should release the footswitches and re-initiate a new cycle.

NOTE If the machine is equipped with a laser beam protection, for the bending at the extremityof the beam, see also the appendix E1.4 and E1.5 “LazerSafe” and appendix E1.6 “Akas”.

7. MAINTENANCE

2/34 Chapter 7 MAINTENANCE Issue 09/2003 HF MEDIUM TONNAGE OPERATOR’S MANUAL – X40882E

CAUTION: Any maintenance operation liable to cause upper beam movement (hydraulic circuit, cylinder, etc.) must be performed with the beam in low position, or using the beam immobilising parts intended for transport purposes (Para. 2.4.4).

7.1. INTRODUCTION This chapter describes the operations required to maintain the qualities and characteristics of your machine. A press brake is exposed to the harsh conditions of a production shop: welding fumes, grinding dust, sheet oil, rust particles, etc. But a modern machine tool like this one is equipped with high-tech precision components: ball screws and guides, notched belt and pulley, proportional hydraulic valves, linear scales, floppy disk drive, etc, which require periodic maintenance. The frequency of periodic maintenance is based on 8 hours of operation per day under normal working conditions. It must be increased accordingly in the event of production at two or three shifts (16 to 24 hours per day), and does not eliminate the need for maintenance according to condition in the event that oiled or galvanised sheets are used for large production runs.


IMPORTANT Use this type of ladder whenever accessing the top of the machine (not an AMADA supply).

7.2.1. CHECKS SPECIFIC TO THE HYDRAULIC INSTALLATION The hydraulic installation of your press brake has proportional hydraulic directional control valves. The reliability of these components depends above all on the cleanliness of the oil. Remember these essential rules: � Every hydraulic circuit is contaminated even before the system is assembled. ��Abrasion wear causes additional contamination during system operation. ��This also occurs when the circuit is topped up with new hydraulic fluid that is supposed to be

clean. For this reason, one should make sure the is filtered before topping up. � Because of this, you are advised not to top up or perform oil changes too often. � All hydraulic circuits must be correctly filtered: well filtered oil degrades very slowly where

as a badly filtered or un filtered oil will increase pollution level which will lead to a faster filter clogging.

IMPORTANT NOTE Failure to apply the above maintenance instructions can lead to a total or partial loss of guarantee cover on the units concerned.

CAUTION: The pump must never run without oil.

CAUTION: To continue operating in complete safety, use only original replacement parts.

7.2.2. OIL CHANGES First oil change: After 1000 hours. Subsequent oil changes: Every 2000 hours or after one year, whichever comes first. Turn off and lock the machine's electrical power supply. Ensure that the lower beam is in its top position. Remove the drain plug (Item 1) and replace it with a hose. Swing the drain handle to open the valve and completely drain the reservoir. 7.2.3. FILLING PROCEDURE Close the drain valve and remove the hose. Reinstall the drain plug. Remove the air filter (Item 2) to fill in the tank. Fill the reservoir with Shell Tellus 46 or an equivalent ISO 46-compliant oil. Reservoir capacity: see Chapter 2, Characteristics. During the filling operation, filter the oil through a 6-micron absolute filter cartridge βx = 200. Check the level. It should be between the minimum and maximum marks on the gauge. Replace the air filter of the hydraulic tank breather (Item 2), Amada Part No. H02160. (Ensure its the correct reference for your machine using part list). Remove the bowl feeder (Item 3) from the high pressure filter.


Replace the oil filter cartridge (for Amada reference see § 7.2 and Parts List). Reinstall the filter bowl feeder.

NOTE After an oil change, do not replace the filter cartridge until the hydraulic unit has been running for half an hour. The purpose of this is to avoid contaminating the new cartridge.

Unlock the electrical power supply.

CAUTION: The legislation in force prohibits the disposal of oil into the environment. Take care to observe the regulations in force in your region.

7.3. RECOMMENDATIONS For these maintenance operations, we have created kits containing the products you need for your machine*:

� Machine maintenance kit, Part No. M90074 (see description). � Numerical Control unit maintenance kit, Part No. M90075.

IMPORTANT NOTE Failure to apply the above maintenance instructions can lead to a total or partial loss of guarantee cover on the units concerned.

CAUTION: All maintenance and preventive maintenance operations must be performed with the hydraulic unit shut down, with the power key removed or main circuit breaker locked.

ACCESS For access at a height (e.g. above 1.8 m), additional equipment must be used (such as an inspection platform, ladder, or stepladder). This equipment should be used only after appropriate training (checking fitness for purpose and stability of the equipment). The manufacturer recommends access via the rear of the machine for the hydraulic components. * : Available in option

During combustion, unidentified organic or inorganic compounds can be formed, as well as sulphured hydrogen and short-chain alkylmercaptans.

2.5 - INDIVIDUAL PREVENTIVE MEASURES

� Barrier cream (on medical advice) or gloves, � Goggles in the event of splashing, � Avoid inhaling oil droplets, � Avoid repeated or prolonged contact, � When handling drums, wear safety shoes.

2.6 - SPECIAL PROTECTIVE MEASURES: not applicable 2.7 - MEASURES FOLLOWING A LEAK OR SPILLAGE

Eliminate or destroy the product: contain and recover using physical means (e.g. absorbent materials), degrease surfaces, eliminate scrap in accordance with Section 6. Do not use dispersing agents in the event of a risk of polluting the environment.

3 - INFLAMMATION AND EXPLOSION 3.1 - FLASH POINT: > 190°C in accordance with AFNOR NF M 07 019 3.2 - SELF-IGNITION TEMPERATURE

> 250°C according to ASTM E 659 standards. This value can be significantly reduced under particular conditions (slow oxidation in strongly divided media).

3.3 - SPECIFIC FIRE OR EXPLOSION HAZARDS

Explosivity limit in air at ambient temperature = 1 to 10% vapour volume. The vapour pressure of this product is too low at ambient temperature for the lower explosivity limit to be reached.

3.4 - EXTINGUISHING EQUIPMENT

� RECOMMENDED: Foam, carbon dioxide, powder � TO BE AVOIDED: Water jet and water spray extinguisher


3.5 - SPECIAL PROTECTIVE MEASURES FOR FIREFIGHTING

Wear breathing apparatus if required due to copious fumes. 3.6 - OTHER RECOMMENDATIONS

��Arrange your installation to avoid accidental oil splashes (e.g. seal failure) on hot covers and cowlings and electrical contacts.

��Hydraulic oil leaks in a circuit under pressure result in jets of a fine spray that can reach very high speeds. Under these conditions, the lower ignition limit of the oil spray is reached for concentrations in the region of 45 grammes per cubic metre.

4 - TOXICOLOGICAL DATA Maximum allowable concentration of oil spray in air: approximately 5 mg/m3.

��Under normal conditions of use, the mineral oils and other components of this product do not present an acute intoxication hazard.

��SPECIFIC TOXICOLOGICAL DATA: In the absence of toxicological data specific to

SHELL TELLUS 46, we are able to provide the following indicative information by analogy with similar mineral oils:

ACUTE ORAL TOXICITY DL50: > 5 ml/kg ACUTE PERCUTANEOUS TOXICITY DL 50: > 4 ml/kg

IRRITATION: - Skin: Considered to be a mild irritant

- Eyes: Considered to be a mild irritant SENSITISATION: Unlikely to sensitise the skin. CHRONIC TOXICITY: SHELL TELLUS products are formulated from severely refined mineral oils which are considered to be non-cancer causing following toxicological tests performed on the skin of mice using the same types of oil. SUMMARY: SHELL TELLUS oils are considered to be of a low level of acute systemic

toxicity. In normal use, they are unlikely to irritate the skin or eyes, or to sensitise the skin. No long-term toxic effect is likely. Users are nonetheless advised to avoid repeated and/or prolonged contact with mineral oils such as SHELL TELLUS, which could lead to irritation or even dermatitis in the event of conditions of poor personal hygiene.


USED OILS: Used oils may contain impurities that are health hazards. They must be

handled with care, and contact with the skin must be avoided whenever possible. Collection and disposal must be carried out in accordance with the regulations in force (see Section 6).

5 - FIRST AID

��Call a doctor ��Whilst waiting for the doctor to arrive, refer to the following guidelines:

INGESTION: No special treatment is normally required. Do not induce vomiting to

avoid the risk of debris being sucked into the respiratory passages. INHALATION: This risk exists only for oils that contain a high proportion of very light

distillates. If inhalation occurs, the mouth and gastro-intestinal tract may become

irritated. In the event of exposure to a high vapour concentration, move the patient to a location with fresh air. Keep the patient warm and relaxed.

ASPIRATION: The risk of aspiration depends on the viscosity, which determines the

ability of materials to be sucked into the respiratory system. In the event of suspected aspiration (e.g. during vomiting), transport the patient to hospital for emergency treatment.

EYES: Wash eyes with copious water, and consult a specialist. SPECIFIC CASE: In the event of contamination via the skin by a high-pressure jet, there is

a risk of contaminant introduction into the patients's system. The patient must be taken to hospital even if there is no obvious injury.

6 - ENVIRONMENTAL PROTECTION Regulations concerning the disposal of oils and lubricants in surface, underground, and sea water: Acts 73-218 dated 23-02-73 and 77-254 dated 8-03-77, information notes dated 14-01-77 and 4-11-80. Regulations concerning waste: Law 75-633 dated 15-07-75 and Act 77-974 dated 19-08-77 and Act 79-981 dated 21-11-79, modified by Acts 85-387 dated 29-03-85 and 89-192 dated 24-03-89 applying to the regulations concerning the recovery of used oil: Law 88-1261 dated 30-12-88.
