BM permanent-magnetic round chuck

Systems

Design: With parallel pole pitch in enhanced magnetic design. An especially strong, permanent-ceramic magnet system with high, evenly distributed holding force across the whole clamping surface ensures the deployment on lathes and grinding machines. The worked-in centring grooves facilitate aligning the workpieces. All round chucks can receive centring (see table, size D and H, for dimension) as required. Machining of the upper plate without impairing the holding force is possible up to a depth of 15 mm in steel and 7 mm in NFM materials. The clamping force can be continuously regulated from zero to maximum. Holding force: max. 120–150 N/cm 2 with ground workpiece clamping surface. Application: Designed for heavy chip removal. For machining on lathes and grinding machines. Note: Further dimensions available on request.

BM permanent-magnetic round chuck

Design: With radial pole pitch. An especially strong, high-energy magnet system made from neodymium-iron-boron (NdFeB) with high, evenly distributed holding force across the whole clamping surface. The round chucks can be equipped with a through-hole to mount centring devices and coolant supply. Holding force: max. 160–180 N/cm 2 with ground workpiece clamping surface.

Application: For machining on grinding machines. Note: Further dimensions available on request.
