Advanced Solutions - Unattended completion of parts in one operation

• 25% faster cycle times than traditional multi-axis turning centers* providingunmatched ROI.

• Proven Unattended Machiningfor increased profits.

• Complex parts completed inone operation for increasedthroughput and cash flow.

*Depending on the application

- PROPRIETARY CONTROL LOGIC allows simultaneous multiple operations and eliminates unnecessary idle time.

- EGS TOOLING SYSTEM assures virtually zero index/tool change time for many operations. (avail.on y-axis models).

- SUB-SPINDLE TRANSFER AT FULL RPM

- ZERO LIVE TOOL ENGAGEMENT TIME

- MANY STANDARD FEATURES TO FURTHER REDUCE CYCLE TIME- Polygon turning- Cut-off confirmation performed with load monitoring- Combination tool holders

25% Faster Cycle Times

- SPINDLE EJECT WITH CONFIRMATION AND AIRBLAST ensures complete part ejection and eliminateschips from chuck interior and spindle bore.

- SUB-SPINDLE LOAD MONITORING assures completion of cut-off operation.

- TOOL LIFE MANAGEMENT AND IN-PROCESS MONITORING OF TOOL WEAR AND BREAKAGE- Index to redundant tooling

- INTEGRAL MATERIAL HANDLING with barfeed interface, Parts Catcher and Conveyor.

- INTEGRATED CHIP CONVEYOR ensures worry free chip control with easy-roll casters and extra clearancebelow the sub-spindle.

Flawless Unattended Machining

Y-AXIS: accuracy and flexibility in turn-milling

A SIGNIFICANT STEP FORWARD TO COMPLETE PROCESS INTEGRATION

With the Y-axis the 835 becomes a com-plete turn-mill center combining the facil-ities of both a lathe and a 5-axis machin-ing center (X, Z, Y, C, B) accomplishing off-center milling-drilling operations that areimpossible to complete with C-axis only.

More Y-axis stroke than any machinein its class!

Allows more complex work and more cutting tools on the turret.

• Up to 24 drilling/-milling/tapping tools.

• Driven tools from 2,000 to 23,000 RPMavailable.

• Virtually zerochip-to-chip toolchange time.

• No fixture issues.

Operations performed with the Y-axis1. 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. Milling of an accurate key-way

7. Enables EGS (Eurotech Gang-tool System)

8. Ability to put over 40 cutting tools

on one 12-station turret

9. Reduces set-ups, while maintaining cycle time speed

10. Improves accuracy by eliminating tool change deviation

SBS: EUROTECH SAFETY SOFTWARETOOL LOAD MONITORING - This systemmonitors the loading of the most heavilyused tools: e.g. 1st OP. cutting tools,roughing tools, drills or U-drills. It ensuressafe automatic machining with limitedoperator presence.

DAMAGE PROTECTION (air bag) - Thisspecial software detects the abnormalload created by a collision during rapidtraverse or within the machiningprocess. When a collision occurs, spin-dle rotation is stopped and the axismovement is halted thus damping theinterference and limiting damage tothe tooling.

NOTE: this function does not preventfrom collision.
