[Introduction] : grinding machine electric permanent magnet sucker is suitable for surface grinding machine, tool grinding machine, EDM machine to absorb all kinds of magnetic permeability workpiece for processing, uniform suction, high processing precision, suitable for processing thin small workpiece. Because there is no power supply in the processing process, there will be no heating phenomenon, no thermal deformation, that is, economic and environmental protection. Even if there is a sudden power failure during the processing, the magnetic field will not be lost, and the workpiece will not move when.
