Clamping Mandrel

The clamping mandrel is designed for grinding the outer contour of the workpiece.

Functional description:

The clamping is initiated by a manually generated torque. The force is transmitted to the clamping sleeve (system SP) via a tilt ring and a clamping bolt. The clamping mandrel is equipped with a pendulum stop to compensate for axial run-out errors. The pendulum stop adapts to the flat face of the workpiece. The workpiece is also supported by a centre point on the machine side. The release of clamping is again initiated via a manually generated torque and is supported by an integrated pressure spring.

Advantages:

- no bending at the clamping mandrel due to inaccurate face at the left end of the workpiece thanks to oscillating end stop
- slim design
- alternative clamping in a partial circle or in a cylindrical bore possible only by replacing the clamping sleeve
