Hydraulic Clamping Tools

Boring, Hobbing and Spindling

Multiple clamping device for vertical machining center
The workpieces are mounted in 2 bores without backlash and clamped.

8 workpieces are clamped in one cycle by means of a central clamping cylinder.

The flat surfaces of the workpieces are hobbed at right angles. In addition, a kidney-shaped slot is cut true to the position of the two bores.

This clamping device guarantees very exact position tolerances.
























Combined centering and clamping device for planetary wheel supports
Königdorn® device on a high-precision vertical machining center for boring and spindling of a planetary wheel support.

The workpiece is centered in the Königdorn® chuck by means of a sizing diameter and clamped via 2 hydraulic swivel clamping elements.

Via a tracing device, the planetary wheel support is aligned after the bore has been pre-machined.
