Description
Version:
- Particularly suitable for highly dynamic milling applications.
- Optimised outer contour using FEM (finite element method) –> robustness thanks to max. rigidity, longer tool life, higher metal removal rate, suitable for all machining strategies.
- With RFID/Balluffchip bore.
- Axial length adjustment, adjustment travel 10mm.
- Reducing adapters can be used.
- Temperature resistant up to 170°C for 4 hours.
- Allows for up to 10x more clamping operations compared with a standard hydraulic chuck.
- Very low tightening torque of the clamping screw – easy handling.
- Patented new hydraulic clamping system – reliable, durable premium concentricity.
Application:
Universally designed for roughing and finishing operations. For clamping tools with shank tolerance h6.
Supplied with:
Hexagon socket drive with T-handle.
