Electropermanent plates are used in metalworking for clamping of ferromagnetic metal workpieces during milling, grinding and drilling works either on universal machines or on CNC machining centers. Magnetic eld is distributed evenly upon the plate surface on depth of 16mm. An electropermanent plate consumes power only at the moment of workpiece clamping/unclamping, which lasts for 0,6-3 seconds. Clamping and unclamping of workpieces is eected only with two buttons. The plateshave high environmental and corrosion resistance.
