“Roller burnishing is a surface finishing process used for precision finishing of a work piece surface. It is a chipless machining method which cold works the metal without cutting or abrading the surface. It removes no metal but rather compresses, or “irons out”, the peaks of a metal surface into the valleys, generating a dense and uniform surface.” Tools can be used on any driven machine spindle with the burnishing process being fast, efficient and cost effective. The mirror like surface finish generated by roller burnishing, combined with a hardened and denser surface, substantially increases part wear, life and corrosion resistance. The added strength improves the part’s fatigue resistance, resulting in decreased failures. The cold working condenses the grain structure of metal, producing an increase in surface hardness. By transferring the force applied by the hardened roller to the surface of a work piece, a plastic deformation of the material occurs. Although this force is relatively small, the use of highly polished rotating rolls in the tool generates sufficient force to deform the material beyond its yield point and produce a smooth surface having displaced the high peaks into the low valleys generated by the pre-machining process. The texture generated provides a surface with a high bearing capacity and low abrasion. Take a look at www.bencere.co.uk for information and animation of a tool working.
