Some very useful surface finishes can be developed by using specialized non-abrasive media to burnish parts. This type of processing is normally performed after abrasive smoothing operation. In addition to improving surface quality and reflectivity, these type of operations can add benefits to the part not usually associated with mass finishing processes. This would include beneficial compressive stress generation and cold hardening which can improve wear and fatigue resistance.
Equipment that can be used to produce these effects includes those shown below:
