EPM-G Lifting-Magnets are specifically designed for lifting thin and hard work pieces in the vicinity of the grinding machine. By adjustable holding force even thin-walled workpieces can be removed from the surface of grinding machines without the workpiece through to pull the machine table, as it is the case with conventional lifting magnets. The pole-reversal built on the lifting magnet system allows to demagnetize the workpiece in maximum quality, so that even hard workpieces can be transported without problems. EPM-G Lifting-Magnets are equipped with a high-quality electro-permanent magnet system which keeps the load safely even during a power failure. The use of the EPM-G has thus particularly in the manufacture of guide rails, tool plates bearing rings and so on.
