Belt Polishing – Produces a high luster finish using grits from 180 to 640. The material can have the smoothness/ brightness improved by conditioning the tubing using a belt polisher. The higher the number the finer the grit and the smoother the surface finish. Belt polishing allows for precise control over the amount of the material removed.
