Abstract
A method of polishing a metallic workpiece includes: mounting the workpiece in a hopper; loading the hopper with a polishing media comprising, by weight percent, more than 98% metallic chips, less than 2% liquid, and less than 0.05% abrasive; and oscillating the hopper for a run time, thereby generating a flow of the polishing media over the workpiece, until a predetermined surface finish is achieved on the workpiece.
