Mandrini autocentranti

The rotating hydraulic cylinders type OVR and OVRK are designed for actuating power operated chucks.

With the maximum permissible pressure of 80 bar, large operating forces can be produced at considerably lower mass and inertia forces than in the past. At the same time, due to a wide pressure setting range, it is possible to actuate several chuck sizes using one cylinder size without any limitations.

OVRK hydraulic cylinders are equipped with a rotating coolant union KDE8-1 for fluid supply into the chip removal area. The maximum permissible coolant lubricant pressure pK is 70 bar. No additional control system is required for a dry run.
