Roller burnishing is a method of cold working metal surfaces to induce compressive residual stresses and enhance surface roughness qualities. The tooling typically consists of a hardened sphere or cylindrical roller. These tools are pressed onto/across the part being processed. This process is typically used where surface finish of the surface is critical.

SBOEVN employ a wide range of roller burnishing tools across our lathes, deep hole borers and milling machines to provide burnished surface on surface critical geometries.
