Used for device and workpiece clamping on machine tools Application

Berg Pneumatic zero point clamping systems NSM-PV series find application for device and workpiece clamping on machine tools. With the clamping systems and attendant clamping bolts, maximum repeat precision of the clamping position is achieved. In the version with blowing-off device, lock and lift-out stroke, the clamping system is safe even when it is in use without personnel.

Due to the mechanical clamping principle with integrated force intensification and locking feature, the clamping system is also suitable for pallets, clamping towers, swivel tables and vertical applications. The installation of the clamping system can be as double, quadruple or as per customer design for multiple application.

Design features

The shape and positional accuracy of the centring cone and horizontal support surfaces guarantee maximum repeat precision during a device and pallet change. The central, spring supported cover and blowing-off of the support surfaces, cover as well as cone make the clamping system insensitive to soiling. A spring draws the clamping bolt into the clamping system. A collet actuates the spring. During this process, the spring force is intensified by an integrated gearing. The blowing air acts as actuating air during clamping. It is necessary to briefly switch off the blowing air during unclamping. The integrated actuating piston unclamps the locking device and releases or ejects the pull stud. Modified versions, e.g. with integrated media transfer are available upon request.
