What is the difference between electropolishing and mechanical polishing?
Electropolishing is an electrochemical process while mechanical polishing is a mechanical process. Electropolishing is a surface treatment that can improve surface finish as it dissolves material from the surface. Mechanical polishing, like machining, alters a surface by cutting material away from the surface. Electropolishing can improve a surface finish on a microscopic level while mechanical polishing can improve a surface finish on a macroscopic level.
