Systems

3 Clamping

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 on ground workpiece clamping surface. Application: Designed for heavy chip removal. For machining on lathes and grinding machines. Note: Further dimensions and round chucks with parallel pitch upon request.

Design: With radial pole pitch. A particularly strong high- energy neodymium-iron-boron (NdFeB) magnet system 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 on ground workpiece clamping surface. Application: For machining on grinding machines. Note: Further dimensions upon request. BM permanent-magnetic round chuck
