Often the last step in the manufacturing process, electropolishing is a “reverse plating” process that removes the outer skin of metal instead of depositing metal on the surface. . The process removes a uniform layer of metal from parts’ surface to remove surface defects. Using a combination of chemicals and electrical current, electropolishing carefully removes surface imperfections and contaminants from metal parts removing as little as .0002”” up to .003”” (.0001” to .0015” per surface) to produce the desired surface finish
