Roller Burnishing Tools

Roller Burnishing Toolis a non-cutting machine process with aim of producing mirror-like surface finishes with low roughness Ra-0.05um to Ra-0.35um, consistantly accurate size and increased hardness of the skin layer through cold working operation. It removes no metal, but rather compresses or "irons out" the peaks of a metal's surface into the valleys.
