Hydraulic Clamping Tools


Workpiece clamping
for rough turning

This Königdorn® mandrel for surfacing hardened workpieces with high axial run-out accuracy, is flanged on a lathe and automatically actuated by means of a pneumatic cylinder.

Königdorn® chuck for the clamping of workpieces with external gear. Clamping on the addendum circle. Turning on the outside diameter and on two inside diameters as well as on the flat surface of the workpiece. Clamping is initiated radially by hand. Run-out accuracy: 0.003 mm.

Clamping mandrels with expansion rates up to 1 % of the diameter
Königdorn® mandrel for clamping a workpiece where the external contour is to be machined by turning on all sides.

Radial clamping via two clamping chambers, axial positioning through positioning pins which are retracted upon initiation of the clamping force via machine hydraulics.

Königdorn® mandrel with highly elastic expanding bushing for expansion rates up to 1 %. In addition, slotted steel bushing to protect against wear and loss of accuracy during serial production.

The expanding mandrel is used for the turning of electrical motors (stators) and is located between centers in the machine. Clamping is performed with the clamping cylinder of the machine through a hollow point.
Run-out accuracy: 0.010 mm.
