ABSTRACT:
A method and apparatus for electro-polishing surfaces of metal objects, which is immersionless and containerless, includes a simplified frame, a cathode mounted on the frame and adapted to be positioned a predetermined distance from the surface to be polished, and a sheet of liquid-retaining material positioned between the cathode and the surface to be polished. When the cathode is negatively charged, the anode is positively charged, and electrolytic bath is introduced to the liquid-retaining material, a circuit is completed between the cathode and anode and an electro-polishing action takes place on the anode. This material retains the electrolyte and allows the gases generated to escape. Various portable adaptations of the invention enhance its use for specific polishing operations.
