Magnetic work-holding device

摘要

A magnetic work-holding device with at least two pole shoes defining a work surface, and a main magnetic core interposed between the two aforementioned shoes; the other sides of the pole shoes are fed by secondary magnetic elements whose poles facing the same pole shoe, have the same sign as the pole corresponding to the main magnetic core. A ferromagnetic yoke encircles the base and the sides of the equipment, short-circuiting the remaining poles of the secondary magnetic elements.
