Turning and automated integrat

The new range of BV vertical

lathes with integrated automa-

tion is the result of EUROTECHs

tradition in the manufacture of

horizontal CNC-lathes equipped

with automatic

loading/unloading systems and

has been designed to meet

customers requirements for

cost-effective chuck machining.

Thanks to the technology of a

vertical moving spindle a simple

two-axis lathe can perform

both unmanned machining

and automatic loading/unload-

ing of parts.

The main features of the BV

series are:

RIGIDITY AND STABILITY:

the main mechanical parts,

such as machine structure,

guideways, ballscrews, spindles

and turret are robustly propor-

tioned to deliver high chip

removal rate.

Available with ASA 6(BV210) and ASA 8 (BV315)

spindle, prepared to accept

chuck sizes 8, 10, 12 and

the pallet systems to load the

parts, the BV vertical lathes can

be equipped with live tools,

C-axis and Y-axis to carry out

complete machining of

complex parts.

PRODUCTIVITY: the fast

indexing servo turret combined

with the high acceleration of

axes and spindles enables the

reduction of loading/unloading

and idle/times (higher perform-

ance at reduced idle times).

The well proportioned machin-

ing area guarantees quick and

convenient tooling-up opera-

tions and makes chip removal

easier.

ACCURACY:

the thermalstabilization of the main heat

sources, of the spindle and tur-

ret along with the use of linear

scales maximizes accuracy.

ENVIRONMENT-FRIENDLY

AND COST-SAVING: the

use of guideways lubricated

with grease eliminates prob-

lems related to the contami-

nation of coolant, thus drasti-

cally reducing disposal costs.

reduction of costs.

T u r r e t

The sturdy and fast indexing

EUROTECH turret (0,1 sec.)

is operated by a servo

motor. The 3-ring Hirth cou-

pling assures maximum rigid-

ity and the turret casting is

cooled to ensure the highest

accuracy. In the versions

equipped with live tools, all

the 12 turret stations are

prepared to accept rotarytoolholders to carry out

milling, boring and tapping

operations.

T o o l s e t t e r

The tool probing system

makes tooling-up operations

safe and quick thus avoiding

the need to manually inputtool offsets.

S t r u c t u r e

The massive rigid cast-iron

slant bed has been designed

following F.E.M. analysis in

order to ensure high rigidity

and exceptional thermal sta-

bility under any machining

conditions.

High Range Low Range

S p i n d l eThe heavy duty EUROTECH inte-

gral motor-spindles (double speed

ratio), with high torque and

power at low range are assem-

bled using the combination of

ball and roll bearings duly

dimensioned to allow powerful

cutting, high accuracy and

superior surface finishing.

Nearly 6of Y-axis travel :turn/mill complex parts in

one operationWith the Y-axis the BV verti-

cal lathe becomes a com-

plete turn-mill center accom-

plishing off-center operations

that are impossible to com-

plete with C-axis only. The

generous stroke of 5.9

places the BV series at the

top of its class.

The main performance bene-

fits achievable with a turning

center equipped with live

tools and Y-axis are:

- improved parts accuracy;

- reduction of down-time;

- reduction of costs;

- increased flexibility tocounter constantly chang-ing market demand.

Operations performed with the Y-axis

. Flat milling in repeated cuts

2. Irregular slot milling (roughness - finishing)

3. Key-way milling

4. Thread milling

5. Drilling and milling grid holes

6. Ability to put over 40 cutting tools on the12-station turret

7. Milling of cam surfaces

8. Reduces set-up, while maintaining cycletime speed

9. Improves accuracy by eliminating toolchange deviation

and ease of operation.

The vertical moving spindle

performs both machining and

automatic loading/unloading

of parts. This solution allows a

simple two-axis CNC-lathe to

become an automatic ma-

chine to carry out unmanned

machining operations.

For loading and unloading of

parts, the standard BV config-

uration comprises a chain with

location prisms for blanks and

a simple conveyor for finished

parts. The loading station is

equipped with a sprung plat-

form to compensate any irreg-

ularity of the blanks.

Air blowers and cleaning de-

vices are provided to eliminate

the chips.

Customized solutions

to achieve maximum productivity.

To offer more flexibility, sever-

al solutions are available to

load and unload parts accord-

ing to machining require-

ments. It is also possible to

link two machines via a turn-

over station to perform com-

plete machining on both

sides of the component.

Solution n1: loading and

unloading operations on a

conveyor for small-sized

blanks or finished parts (up to

5.5)

Solution n2: (parts up to

9.8 dia.): a pick-up station

composed of a range of

conveyors that line up and

convey the blanks to the

loading station; the finished

parts are loaded on to a sepa-

rate conveyor.

Solution n3: two machines

linked by a turn-over station

and a storage system for

blanks and finished parts.
