Hydraulic Clamping Tools

Worm and Rotor Grinding

Hydraulic mandrels and chucks
for worm and rotor grinding
During this application of a clamping mandrel for worm grinding, a worm with two different internal diameters is clamped on a flanged mandrel. The clamping mandrel, which is firmly mounted on the machine spindle, is clamped via the clamping cylinder of the machine. Automatic loading of workpieces is possible.




The opposite Königdorn® mandrel is loaded outside the machine. Automatic clamping by means of an electrical or pneumatic screwing device is also possible here. The clamping mandrel is clamped on the shaft in a chuck and supported via the tailstock center. Run-out accuracy: 0.003 mm.


Chuck for grinding of rotors for compressed air as well as refrigeration technology. The chuck is mounted on the machine spindle via an intermediate flange which is configured as a hydraulic chuck. The pressure pistons are actuated and the necessary clamping pressure is generated via pressure rods integrated into the intermediate flange. A spring-loaded locating center allows the automatic exchange of workpieces. The rotors are supported via the tailstock center. Workpiece exchange as well as workpiece clamping are monitored via an air inlet control device.
