5.1.1 Adjusting the near point of X and Y axes1) To show MAINTENANCE MAKER box, choose “MAINTE.” tab. Holding Ctrl + Shift keys,

click right mouse button.

2) Move the pointer onto the MAINTENANCE MAKER. Tick the checkbox.3) To display MACHINE I/O screen, choose “MAINTE.” tab – “TOOL” – “MACHINE I/O”

screen buttons.4) Choose “0/1” PORT in “MACHINE CH0”.

5) Find NEAR POINT buttons in the screen because they will be used during the followingprocedure:

• Under READY ON condition, Near Point button is normally on (On-screen button:Pressed).

• When the near point detection limit is ON, Near Point button is off (On-screen button:Not pressed).

6) Move the axis against stroke end at MEDIUM speed by 50 mm.

7) Perform Zero Point Return to the axis to be adjusted.8) Immediately press “MAINTE” screen tab and “F6” key (POSITION) to display “Machine

I/O” and “POSITION” screens.9) The axis will start moving in Zero Point direction. Once Near Point detection limit switch

turns ON (On-screen button: Not pressed), it will start moving against Zero Point. Then,the feeding speed will slow down. After that, it will move towards Zero Point again.

10) Zero Point Return process is completed after Near Point detection limit switch is turnedON again (ON-screen button: Not pressed), showing “#” sign in “PROGRAM POSITION”of POSITION display.

11) Confirm that the distance between the point where Near Point limit switch is turned on atthe second time and the point where Zero Point return is completed is 0.2 - 0.4 mm.

12) Move the axis from the point where Zero Point return is completed to Stroke End at

MEDIUM speed.13) Confirm that the distance is 1.5 - 3.0 mm.14) If the value in step 11) or step 13) is out of the specified value, adjust the Near Point

adjustment bolt finely. Then repeat the procedure from step 1).15) Fasten the near point adjustment bolt properly.

7) Stop feeding when the bit changes from “0” to “1” (When the detector detects Z phase of the linear scale)

8) Make sure the coordinates in the manual operation box is within the below value.

X axis 4 - 6 mm

Y axis (-4) - (-6) mm

Note The reason why the distance between the stroke end and (-) Z phase should be 4 - 6 mmis that the guaranteed Zero Point distance is the point within 5 mm of Z phase.

9) If the value is out of the above stated, relocate the detector and carry out step 2) - 8) again.Refer to the following relational drawing of Dog and Scale when you adjust the positiondetector.

10) If the value is within the above stated, recheck the step 13) in the previous section (5.1.1 Adjusting Near Point of X and Y axes). This is because the distance will change from theone in Near Point adjustment procedure due to linear scale adjustment.Refer to the following positional drawing.

CLASS 10

CLASS 20

1) Wire should notcontact

2) Retry sensor

Pulley for Angle Master

3) Pick arm



MeiKeyo-475534-A


1) Relocate the pipe position adjustment block so that the wire will run in the center of the pipe.2) Relocate the retry sensor in side-to-side and front-to-back directions to make the wire run in the

center of the pipe. If it does not run in the center, breakage possibility will get high. See the nextpage for the adjustment method.

3) Reposition the ceramic protection pipe of pick arm so that it will slightly touche the wire. Assurethat the wire does not touch too closely and not push the pipe. (Pick arm is a vibration preventive

device and assures the re-try sensor detection function).4) Adjust the pick arm so that it does not apply the load to the pipe, which leads to smooth rotaion of ceramic protection tube. (If the pipe contacts with the wire, wire chips will be generated, whichcauses a clogged auxiliary die B)

5) After adjustment, make sure that the wire is located in the center of the wire detection area,following the below steps.

a. Move Z axis upward up to the maximum with the wire threaded through.b. Move U axis in (+) direction. Find the location where the red pilot lamp turns off, looking at

the on-screen U axis coordinates.c. Move U axis in (-) direction. Find the location where the red pilot lamp turns off, looking at the

on-screen U axis coordinates.d. If the both absolute values where the pilot lamp turns off differ, relocate the sensor and pick

arm.e. After returning U axis to the origin point, carry out the same procedure for V axis. If the both

absolute values differ, relocate the sensor and pick arm.f. After determining the wire detection area, return U and V axes to the origin point. Make sure

that pick arm does not push the wire. Also make sure that ceramic protection pipe rotatesalong with the wire and that the pilot lamp for the wire looseness detection sensor does notflush.

13.4.3 Adjusting the pretension and checking main tension

1) Install the Ø 0.1 diamond dies.2) Set 3 kg wire spool of Ø 0.1 and thread it.

3) After setting PT=14, WT=2, WS=12, press “WIRE” button. Wait more than 30 secondsuntil the bobbin diameter compensation begins before starting adjustment.

4) Adjust the band-resistors for Ø 0.1, which is located near PT motor to have the pretensionof 200g±10g (1.9±0.1N). (Refer to “9.2 Adjusting the pretension” for details.)

5) After setting PT=10, WT=3, WS=12, check the wire tension between electrodes is320g±20g (3.1±0.2N). If the value is out of the specified, readjust.

13.4.4 Checking the spool diameter correction function

1) Set a brand new 3kg wire spool and thread the wire.Read the value of P1494 (short) in the screen in 30seconds after pressing WIRE button.

2) Replace the spool with the one of 1.6kg or another which remaining wire is 2kg or less.

3) Measure in the manner of the previous section andensure that the pretension is 180 – 220g (1.76 – 2.1N)

Note About P5026 (hex)The last digit value represents the compensation command for the spool diameter. e.g. A brand new bobbin is ”F”. The valuebecomes smaller as the diameter becomes smaller.The last digit value represents the compensation command for the spool diameter. e.g. A brand new bobbin is ”F”. The valuebecomes smaller as the diameter becomes smaller.

13.4.5 Adjusting the cutting tension in case of Ø 0.1

1) Set a brand new 3 kg wire spool of Ø 0.1. Thread thewire up to around the upper fluid nozzle.

2) Short-circuit the both edges of the cutting energizer withan alligator clip or other.

3) Choose “AT CUT” button in “AT 1/2”. After the pushingplate (pad) comes out, set the tension meter carefullyon the upper portion of AT unit (between the maintension roller and the wire pushing roller).

4) Separate the wire retaining rollers forcibly by hand, holding thetension meter. Measure the tension at this time.

5) After checking the tension, cut the wire to stop the procedure. If measuring again, feed the wire by 30 cm or more to bring out thenon-deformed section.

6) Check the present tension data in “WIRE CUTTING” screen.

7) To have the cutting tension value of 500±20g (4.9±0.5N), measurethe tension a few times while adjusting the last two digits of thecutting parameter finely within “ 60” - “80” . Check the wire for redheat and the tip deformation, too.

8) Once tension parameter value is determined, save the pitch error data to the dedicated USB memory. In case of Ø 0.1BS wire, savethe data as follows:File name: “01CUT.INI” Data range: P3004 - P3005.

The last digit value representsthe compensation commandfor the spool diameter.e.g. A brand new bobbin is ”F”.The value becomes smaller asthe diameter becomes smaller.

The last second digit valuerepresents “PT” specified inthe machining condition.e.g. PT14 is “D”, and PT16 is“F”.

Before applying the tension tothe wire, “Deflection Removal” iscarried out.In this process, the cuttingenergizer will return to its placetemporary. When it comes outfor the 2

ndtime, the pushing

plate will come out.

13.4.6 Adjusting the cutting tension in case of Ø 0.15

1) Before adjustment, deactivate “WIRE STRAIGHTPROCESS” and “FINE HO. INS” in “AT SCREEN2 asØ 0.15 wire is compliant with the wire straighteningtreatment.

2) Replace the current wire pushing plate with the one

for Ø0.15.

3) Measure the tension in the same manner as Ø 0.1.To obtain the cutting tension value of 700±50g(6.8±0.5N), measure the tension a few times whileadjusting the last two digits of the cutting parametersfinely within “ 60” – “80” . Check the wire for red heatand the tip deformation, too. Also, confirm that thewire top location has not moved due to the forcesgenerated by the wire backing upward motion whencarrying out wire-melt-cut and so on.

4) Write the last two digits of the cutting parametersdown. Change the tab to “WIRE STRAIGHT”. Thenenter the value you wrote down.

5) Recheck the wire tip. Save the data into the dedicated USB memory as follows.

File name: “015CUT.INI” Data range: “P3006 - P3007”File name: “015ANL.INI” Data range: “P3306 - P3307”

13.4.7 Adjusting the wire sag detection sensor

1) Inserting Ø 0.1 wireWhile running the wire, temporarily reposition the RETRY sensor and anti-vibration pickarm so that the wire will be located approximately at the center of the detection area.

Run the wire after adjustment. In case of unstable detection, LED will flush. If so,readjust. Shift the sensor slightly back and forth since LED light ray dose not alwayscome out straight.

If the lamp still flushes, incline the sensor by approximately 0.5 mm.

Note Be sure to fasten the screws properly after adjustment.

E.g. The initial value of “Ø 0.15BS” is ”0475”. The firsttwo digits, “04” represent theelectric current data, the last twodigits, ”75” represent the tensiondata (hexadecimal number).The tension grows in correspondto the data increase.

5) Confirm the difference betweenData <1> and Data <2>is 200 ±100.

13.4.8 Confirmation

1) Perform AT CUT for about 5 times without threading the wire to the end.Check the wire tip for red heat and deflection. Also confirm the chips are collected bysuction function.

2) Perform AT INSERT for about 5 times.Confirm the wire does not slip out of the pulley.Ensue that “Wire transfer completion detection” works properly.

3) Perform AT CUT for about 5 times with the wire threaded to the end. After AT CUT, confirm the wire is between the upper and lower power feeders.Confirm that AT INSERT can be performed after AT CUT.

4) After threading Ø 0.1 wire, run it.Confirm that there is no continuity between E-side and the guide pipe while running the

wire.

5) Run the wire for about 10 seconds after threading Ø 0.1 wire. After stopping the wire, cut it at auxiliary die A and cut it at the cutting energizers. Checkthe curling rate is 5% or less (Width: 15 mm) in every 300 mm, and not rolled spiral. Therate of the original wire on the bobbin should be 3% or less (Width: 30 mm) per 1 m.

6) Move Ø 0.1 wire to the initial position. (Move the wire tip to the cutting energizer)1. Move Z axis upward and downward. Confirm that no sag is found in the wire above
