Electro-permanent magnetic chuck PRF series

In all manufacturing processes involving wheel turning, bearings, rings and flanges, a common problem is how to clamp the workpiece without deforming it. The traditional mechanical clamping tools can cause ‘ovalization’ and the deformation of the piece. radialpole-15Radial Pole clamps the piece from its base surface. There are no obstacles to the tool path; the complete machining operation can be made in a single setup. Using the pole extensions allows you to raise the piece from the magnet surface, making both inner and outer diameters fully machinable. The uniformity of clamping, a typical characteristic of the magnetic system, removes vibrations with consequently enormous advantages in terms of machining tolerances, tool life, chip removal and machine productivity. The new PRF series in monolithic technology is equipped with a totally metallic surface; this guarantees a great robustness and a perfect isolation of the components located within the system. The rectangular pole offers, compared to alternative trapezoidal-pole solutions, consistent performance along the radius (then on pieces independently from the diameter) and constant depth of the magnetic flux.
