Hydraulic Clamping Tools

Coronieren® (Coronating)

Workpiece clamping for Coronating
The high machining forces of Coronating impose extreme requirements on the clamping devices. Due to the high run-out precision, the enormous achievable torque and optimal stability Königdorn® tools are particularly suitable for this machining process.

In this example the clamping mandrel is directly mounted on the workpiece spindle and is actuated via machine hydraulics.

The built-in pressure transducer generates the necessary clamping pressure. In addition, the workpiece is pressed against a coated contact ring via an axial clamping device in order to achieve the required torque. Run-out accuracy: 0.003 mm. An integrated operation indicator increases the operating safety of machine and Königdorn® tooling.
