Summary
Magnetic workholding has become a viable alternative for a broader range of operations due to recent advances in magnetic chuck technology. Among these developments are better permanent magnet materials; pole extensions and other instruments that permit five-side machining and chucking of uncommon workpiece configurations as well as reduce distortion; and controls that allow variable magnetic power and reduce residual magnetism.

Magnetic chucks attract new users.
Magnetic chucks have long been almost standard equipment on many types of grinders. Recent developments in magnetic chuck technology, however, are making magnetic work-holding an option for machining operations from milling to EDM--and saving users time and money compared with mechanical workholding fixtures.
Advances in chuck technology include improved permanent magnet materials; pole extensions and other devices that allow five-side machining, chucking of unusual workpiece configurations, and minimiz...See the full content of this document
