Bolt chuck with hydraulic compensation

For sensitive workpieces in large-scale production

The chuck is used for unround, deformation-sensitive workpieces that are to be clamped radially and with planar pull.

Technical features

Finishing thin-walled cams

With this clamping method, thin-walled cams can be clamped on the raw contour and the bore and flat surface 5µm can be produced.
Achieving final precision for sensitive brake discs

In many cases, the surfaces of sensitive brake discs do not reach the necessary flatness after the final machining operation, because the clamping diameters are not sufficiently round. In this case we can help with our hydraulic compensation principle.
Hard turning of ball bearing rings

Not all diameters of a bearing need to be grinded, but the roundness requirements are in grinding quality range. You can achieve this quality thanks to our hydraulic clamping principle, this leads to enormous cost savings.
