Description
Version:
- Extremely low axial forces for low flank pressure and perfect surface quality.
- Torsion damper and compensation mechanism in the circumferential direction.
- Depth of up to 150 mm can be achieved with ⌀10 interference contour (for thread size M0.5-M3).
- Suitable for internal coolant supply of up to 80 bar.
- Suitable for taps and fluteless taps.
- Suitable for right-hand and left-hand threads.
- Suitable for blind and through holes.
- Minimum length compensation in push and pull direction.
- Drastically reduces the flank pressure on old and new CNC machining centres.
Advantage:
- Reliable processes thanks to smooth operation, even under torque load.
- Longer tool life for the tap and fluteless tap.
- Significantly smaller outer diameter than previously available.
- Significantly more internal cooling directly on the tool than conventional synchro chucks (for ER8).
- Concentricity is twice as good, for the lowest flank pressure.
- Damping when reversing the direction of rotation ensures fewer tool breakages.
Supplied with:
Spanner
Note:
Products No. 338131 – 338135 only when used with CENTRO/P collets (No. 309365 – 309372). The weaker the axial force, the better the quality, the lower the wear, the longer the service life, and the safer the process.
