Radial Pole Magnetic Chuck for Vertical Turning, Grinding

SMW Autoblok’s Radial Pole permanent electromagnetic system from Mag Autoblok, a division of SMW Autoblok, is used for vertical turning and grinding of thin wall parts such as bearings, rings, gears and flanges. 

When using three solid pole extensions and using the remainder with spring-loaded pole extensions, the system enables the chuck to clamp workpieces with nondistortional clamping from the base surface. That means there are no obstacles to the tool path for three sides of the part and no deformation which can occur with mechanical clamping. Parts can be machined with extremely high accuracies of 10 to 20 microns which, in many cases, can eliminate grinding.

Because users are holding the part for the base, setups are dramatically reduced. Pole extensions enable users to raise the piece from the magnet surface making the top, inner and outer diameters fully machinable. This process is said to dramatically reduce part distortion due to clamping with zero distortion and enabling far more accurate part processing. 

Additional features of the Radial Pole Magnetic Chuck include full use of the machine table; complete machining operation in a single setup; and automatic shimming for stress-free operations.

SMW Autoblok’s Mag Autoblok division includes a full line of permanent electromagnetic chucking systems for quick and flexible workholding on horizontal and vertical milling machines, vertical turning centers, FMS systems, grinding machines, EDMs and more. A full line of magnetic lifters for loading and unloading workpieces is also offered.
