Compressed air – Hollow clamping cylinders

"Pneumatic power for delicate actuation."

The compressed air hollow cylinders were specially developed as a clamping unit for power clamping devices on machine tools with RPMs up to 8000 min‾¹. Rotating clamping cylinders are attached to the spindle end of a lathe or a grinding machine. They have the task of generating an axial force for the rotating power chucks mounted at the spindle head. This axial force is transmitted via a connecting link, designed as a tube or a drawbar, going through the spindle bore to the respective power chuck used with an adapter.

Integrated safety valves for maintaining the clamping pressure!

The safety valve system integrated into the cylinder enables the clamping pressure to be maintained in the event of a hose rupture or a sudden drop in pressure, thereby preventing premature release of the clamped workpiece in the power chuck until the spindle comes to a standstill.
