Roller Burnishing Tool
Roller Burnishing Tools for All Applications
Roller burnishing improves surface finish of parts, eliminating processes such as grinding and honing. 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.
