Application: The pressure medium in the hydraulic system is forced into the narrow space around the clamping part, which then centers and clamps the tool. When the pressure screw in tightened to the end position the system is fully pressurized and maximum clamping power is obtained. Releasing the pressure screw reduces the pressure and the clamping part returns to its original measurements. The tool can then be removed.
