What is burnishing and burnishing?
Burnishing is the process of flattening the surface of the workpiece plastically by using a smooth but hard tool that is rubbed on the surface of the workpiece by applying a certain amount of pressure. This pressure exceeds the yield strength of the material to undergo plastic deformation. Burnishing makes the surface flat, smooth and shiny.

What is roller burnishing?
Roller burnishing is a surface finishing technique in which hardened, highly polished steel rollers are brought into pressure contact with a softer piece part. 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 sub-surface material. The result is a mirror-like finish and a tough, work-hardened surface with load-carrying characteristics that are superior to finishes obtained by abrasive metal-removal methods.
What is roller burnished surface?
A roller burnished surface is smoother and more wear-resistant than an abraded surface of the same profilometer reading. Profilometers measure roughness height. Abrasive finishing processes remove metal by cutting or tearing it away, and while this usually lowers the roughness profile, it leaves sharp projections in the contact plane of the machined surface.

Why is burnishing metal important?from accubrass.com
The process condenses the metal’s structure, increasing its resistance to fatigue. Burnishing also reduces the risk of corrosion. The metal burnishing process decreases roughness and removes tiny burrs and dents which can attract rust.
Why is burnishing undesirable?from en.wikipedia.org
Burnishing is normally undesirable in mechanical components for a variety of reasons, sometimes simply because its effects are unpredictable. Even light burnishing will significantly alter the surface finish of a part. Initially the finish will be smoother, but with repetitive sliding action, grooves will develop on the surface along the sliding direction. The plastic deformation associated with burnishing will harden the surface and generate compressive residual stresses. Although these properties are usually advantageous, excessive burnishing leads to sub-surface cracks which cause spalling, a phenomenon where the upper layer of a surface flakes off of the bulk material.
