Hydraulic Clamping Tools

Machine Elements

The Königdorn® as tool clamping device
The illustration below shows the grinding spindle of a gear grinding machine. This grinding spindle has an expansion chamber with a run-out accuracy of 0.002 mm to the bearing locations for centering the CBN grinding wheel.

Similar spindles are also manufactured for mounting diamond dressing wheels. These are used in grinding machines for dressing grinding wheels with high-precision profiles.

The clamping system of Königdorn® devices can easily be transferred to elements of general machine construction.

The clamping force is initiated here, as with most Königdorn® devices, manually with a tool at the most accessible locations.

The illustration on the right shows a Königdorn® chuck for backlashfree centering of a tailstock center.
