Cogsdill Roller Burnishing Tools explained
"Roller Burnishing is a surface finishing technique in which hardened, highly polished steel rollers are brought into contact with a softer component"
As the pressure generated through the rollers exceeds the yield point of the piece part material, the surface is plastically deformed by cold flowing of the sub-surface material. The result is a mirror-like finish and a tough, work hardened surface with increased load carrying characteristics which makes roller burnishing superior to finishes obtained by abrasive metal-removal methods.
A roller burnished surface is smoother and more
wear-resistant than an abraded surface of the same reading.
Roller Burnishing DISPLACES material rather than removing it.
Material in microscopic "peaks" on the machined surface is caused to cold flow into the "valleys", creating a plateau-like profile in which sharpness is reduced or eliminated in the contact plane.
The Burnished surface will last longer under working conditions in contact with a mating part.
