The electropolishing process may improve a surface finish by up to 50 . The electropolishing reaction removes material while it improves surface roughness. Because of the material removal process runtimes are often limited to maintain dimensional tolerances. Limited runtimes result in real world surface roughness improvements from 10 to 35 .
