What is Burnishing ?
Roller Burnishing is a Super-finishing process. It is a Cold Working process which produces a fine surface finish by the planetary rotation of hardened rollers over a bored or turned metal surface.
Since all machined surfaces consist of a series of peaks and valleys of
irregular height and spacing, the plastic deformation created by roller
burnishing is a displacement of the material in the peaks which cold flows under
pressure into the valleys. The result is a mirror-like finish with a tough, work
hardened, wear and corrosion resistant surface. Lapping and Honing is
eliminated.
