Hydraulic Clamping Tools

Tool Grinding

Königdorn® chuck for use on
tool grinding machines

The drawing above shows the example of a hydraulic chuck for clamping of a waver hob with tapers on the end.

The operational area is the manufacturing, grinding and resharpening of this hob profile on high-precise tool grinding machines.

  The clamping pressure is actuated by axial pushing of the waver hob by the tailstock of the machine.

Beside the clamping function, the hydraulic expanding process equalizes the angle tolerances.

An integrated ejector allows a more ergonomic tooling set-up. Run-out accuracy: 0.003 mm.

Automatic chuck for grinding and sharpening tools. The chuck is used on CNC tool grinding machines with automatic loading. The cylinder is clamped with two pistons. In addition, a cleaning device can be connected in the center so the Königdorn® chuck can be flushed by air or coolant after each machining cycle.
