Clamping Mandrel

The clamping mandrel is designed for a turning operation of the outer contour, as well as for milling and drilling the workpiece.

Functional description:

Clamping is initiated via two drawbars on the machine side. The inner drawbar actuates the collet (system SZ) by exceeding the idle stroke via a clamping bolt (system SZ) The clamping diameter of the collet is conical. The face clamping is initiated via the outer draw bar and a thrust piece. This triggers a turning and pulling movement that swings out the face clamping fingers and pulls them flat against the workpiece. Both clamping functions are released via integrated disc spring assemblies.

Advantages:

- pre-centring via collet
- face clamping in very small spaces due to swivelling clamping fingers
