Pallet Clamping and Zero-Point Clamping Systems
BERG Spanntechnik pallet clamping heads are used in machining centers for highly accurate and rapid workpiece change.
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.
BERG Spanntechnik series SPH clamping heads are primarily used for horizontal pallet clamping. The heads form the basis of a highly rigid, high precision repeatable workholding solution. In addition to clamping heads, non-active units are available for setup and storage stations. Heads are supplied as a matched set with 0.005mm accuracy.
Clamping heads of the series SPH-V are principally used in machining centers for vertical pallet clamping. The series SPH-V is based on the basic principle of the SPH. The additional internal self-locking system retains the clamping force even when hydraulic pressure is not present. It is possible to machine workpieces on a vertical pallet after clamping without a hydraulic connection - without any reduction in safety!
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.
Clamping force measuring gauges for pallets are intended to quickly measure the holding force of individual clamping heads. Pallet clamping adapters are per-application based, and are fitted according to the specifications of the customer's pallet system. Clamping adapters can be or have been provided for various pallet systems: BERG, Rohm, Mazak, OTT, Schunk, Erowa, and others.
