Abstract
An apparatus and method especially adapted for electropolishing reactive metal workpieces which require aggressive electrolytes. It incorporates a single, closed, pressure-tight polishing chamber into which metal workpieces are placed for a multi-step operation. All electrolyte cleaning and rinse fluids are pumped in and out of the chamber as required for sequential operations, and vacuum assisted purging and dying removes the electrolyte or polishing residue from the chamber after each step.
