Zero Point Clamping Systems
BERG Spannetechnik NSM zero-point clamping systems are ideally suited for retrofit applications, as well as other situations where a compact yet highly precise pallet changing system is needed.
NSM-HV series zero point clamping heads are used for workholding pallet clamping as well as other applications on machine tools. With the clamping heads and matching retention bolts, extremely tight tolerance clamping position repeat precision can be achieved.
NSM PV zero point clamping heads are used for fixture and pallet clamping on machine tools. With the clamping heads and the associated clamping bolts provide for the highest levels of clamping position repeatability. Due to the mechanical integrated booster and lock, the clamping head is also suitable for pallets, tombstones, pivot tables and vertical applications. The chuck can be configured as double, 4-fold and custom multi-application.
Pull studs are the interface between devices, pallets and the clamping systems of the machine tool. For applications with two, four or more clamping heads, solid bolts are used for center position, sword bolts are used to determine the angled position and retaining bolts are exclusively used for vertical positioning. Versions are available for both front and rear installation. Parallel to the applications of the BERG clamping heads with support cone, screw-in bolts are available as solid bolts and retaining bolts with screw thread. These are used for very high drawing-in forces and maximum stability in a minimum amount of space.
