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.
- Axial length adjustment, adjustment travel 10 mm.
- Reducing adapters can be used.
- Resistant to temperatures 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.
Optional extras:
Pull studs (AB) No. 308600 − 308802, AB pull stud wrenches No. 308820 / 308835, Reducing sleeves No. 302135 − 302187.
Warning:
Intended use
Reasonably foreseeable misuse
- Hydraulic chuck for clamping rotationally symmetrical tools.
- For work in industrial environments.
- Observe minimum clamping depth.
- If using custom designs, observe the specifications in the applicable drawings.
- Observe the maximum operating speed and adapt it to individual conditions if necessary.
Reasonably foreseeable misuse
- Do not use in explosion hazard areas.
- Not for use in areas where high concentrations of dust, flammable gases, vapours or solvents are present.
- Do not combine extensions.
- Not to be used for workpiece clamping.
- Do not heat with a shrink-fit unit.
