In general terms, when properly applied, electropolishing can reduce microfinish values by 50% with a removal of .0005 in. from each surface. Chart B clearly shows that maximum benefit is achieved in this area, and that removing much more metal does not continue to improve surface finish.

It is important to note that electropolishing is best suited for improving microfinish values on complex or fragile parts. Many other microfinish improvement methods such as grinding, lapping or harperizing are not suitable on multi-faceted parts or fragile stampings.
