Abstract:
The present invention provides a new and improved method for differentially polishing the surface of metallic materials in a dry tumbling operation. The process involves providing a finish of a first type on a metallic object. A protective coating is then placed over the first area. The object is then placed into a tumbling drum with a dry polishing media and tumbled to provide a polished finish on the unprotected surface. A secondary feature of the present invention provides the ability to flash off the polishing compounds between polishing batches to prevent build up of polishing residue and provide more consistent results.
