Metal finishing refers to the process of altering a material’s surface to enhance its quality and aesthetic. Metal can also be finished to prepare its surface for paint adhesion or achieving a specific micro-inch finish.

The most common type of metal finish is a straight-line or grain finish for decorative purposes. In most cases, this process can be accomplished using standard abrasive belts. However, depending on the type of material, the desired result may require a combination of abrasive belts and brush heads.
