Burnishing or burnish metal is a plastic deformation that enhances outer appearance and texture of any metal.
It is a plastic deformation that enhances outer appearance and texture of any metal.
Burnishing is eminently used manufacturing for improving surface hardness, finish, shape, and size of the workpiece. It considerably a forming operation that is occurring on a small scale. This plastic deformation process, if done in a controlled manner, can have desirable effects and benefits including: prevents corrosion and stress fatigue, creates compressive residual stress to the surface, combats fatigue failure, closes porosity, and produces textures surfaces for eliminating visual defects.
Upon our operations, we use abrasive tools that can bring out tough, work-hardened and mirror-like surface finish along with load-carrying characteristics. That is how the burnished surface is considered superior to finished components that are achieved through abrasive metal-removing procedures. To burnish cold drawn steel bars imparts a brighter and smoother surface to the material. Our one-of-a-kind machining methods are applied to a whole variety of part configurations:
