Description
Version:
- Slim design (4.5° contour, identical to shrink contour according to DIN 69882-8)
- With RFID/Balluffchip bore.
- Axial length adjustment, adjustment travel 10 mm.
- Reducing adapters can be used.
- Temperature resistant up to 120°C for 4 hours.
- Up to 10× more clamping operations possible compared to a standard hydraulic chuck.
- Very low tightening torque of the clamping screw – easy handling.
- Patented new hydraulic clamping system – reliable and durable premium radial run-out.
Advantage:
Same properties as shrink-fit chucks:
- Accuracy
- Extremely slim, identical interference contour
- Better damping
- Simpler to use
- Flexibility (through reducing adapters)
- No shrink-fit units required (costs, energy consumption)
Application:
Particularly for use in tool and mould making and wherever a reduced interference contour is required.
For drilling, reaming and milling.
For clamping tools with shank tolerance h6.
For drilling, reaming and milling.
For clamping tools with shank tolerance h6.
Supplied with:
Hexagon socket drive with T-handle.
