Description
Version:
For use on all CNC lathes with Sauter turret and drive coupling DIN 5480 or machines with BMT turret with drive coupling DIN 1809. Clamping of tools in driven tool using ER collet with external/internal nut or VARIA VX quick-change system under license from EWS. External cooling via innovative coolant management, internal cooling through the tool centrally through the spindle.
Version IK – with ceramic seal set, pressures up to 70 bar, with full dry-run capability. For use on BMT turrets. Ratio 1:1. Version with internal cooling (internal) max. 70 bar.
Version IK – with ceramic seal set, pressures up to 70 bar, with full dry-run capability. For use on BMT turrets. Ratio 1:1. Version with internal cooling (internal) max. 70 bar.
Advantage:
- Design optimised for weight and geometry.
- Process reliability thanks to high-quality components, long working life.
- Transmission of high torques.
- 100% inspection – every driven tool undergoes a run-in program.
- Through cooling: specially developed and patented seal.
Application:
As many machining steps as possible in one clamping set-up. Where space (available clamping positions) in the revolver is at a premium.
Suitable for:
- ALEX-TECH: VT-27G; VT-30BL; VT-33BL
- DMC: DL 21; DL 22
- FOCUS CNC: FBL-230; FBL-250; FNL-250; FBL-320; FNL-320
- HWACHEON: CUTEX 160; CUTEX 180; VT 450
- LEADWELL: T-7I
- SMART: NL 2000
- SMEC: PL 240; SL 1500; SL 2000
- Takamaz: XT-8; XYT-51; XYT-65
Supplied with:
Driven tool for collet: including clamping nut and hook spanner. Driven tool VARIA VX: including chuck key.
Optional extras:
Suitable inserts Varia VX No. 319802 – 319888, ER quick-change adapters No. 319761 – 319781, ER collets No. 308941 – 309878, ER clamping wrenches No. 319002 225AX.
Note:
- Other drive types (such as DIN 5482), ratios, dimensions, BMT etc. on request.
- IC tools (with through cooling) will not run dry with standard seal, coolant filtering < 50 µm.
- Recommendation: Tighten version VARIA VX with a torque tool (max. 6 Nm).
- For heavy-duty milling work, a variant with tapered roller bearings is recommended on request.
Please note that you must check the compatibility of the holder with your machine before purchasing. We cannot guarantee that it will fit correctly.
