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 minimize distortion; and controls that permit variable magnetic power and minimize residual magnetism.
Another factor in increasing use of magnetic chucks for ...
