Clamping Mandrel

For clamping of drive shafts.

Article number HD400064

  • Mounting position: vertically suspended with tailstock
    Clamping system SK

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

Functional description:

Clamping is initiated via two drawbars on the machine side. The inner draw bar actuates the wedge-shaped clamping jaws (system SK) via a clamping bolt on the small clamping diameter. The outer draw bar actuates the wedge-shaped clamping jaws (system SK) via a second clamping bolt on the larger clamping diameter. It clamps the workpiece in the partial circle diameter of the internal gearing. The workpiece is axially clamped in the rounding of the gearing bottom via a toothed stop disc. In addition, the clamping mandrel is supported on the tailstock side via a fixed centre point.

Advantages:

- two independent clamping points for accurate and repeatable workpiece alignment
- additional protection against soiling due to sealing air in the clamping mandrel
- a toothed end stop ring in the centre between the two clamping points enables machining of both workpiece ends in one clamping setup.
