FAQ

1、Q: What is the difference between electropolishing and mechanical polishing?

A: 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.

2. Q: What is black oxide coating?

A: Black oxide coating is a process which provides a conversion coating on iron which changes the surface of the material to a naturally occurring black iron oxide. It provides a pleasing aesthetic finish as well as a minimal change in surface dimensions,0.0005”(5 millionths of an inch). Though the black oxide plating does provide some corrosion protection by itself it is necessary to put a protective oil on this finish to keep it from rusting.
