Other Finishing

Surface finishing is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property. Finishing processes act on the surface of the part to prepare it as the finished surface or as pre-coating preparation. Common finishing processes, such as cleaning, striping, or polishing require the use of chemicals, surfactants, detergents, acids, or abrasives. Deburring removes sharp edges from parts and is accomplished by tumbling parts together, vibrating parts with an abrasive agent, or sandblasting parts. Honing and lapping are accomplished with tools. These processes serve to finish edges and surfaces, and to flatten or straighten parts. The purpose of surface finishing is to improve appearance, adhesion or wettability, solderability, corrosion resistance, tarnish resistance, chemical resistance, wear resistance, hardness, modify electrical conductivity, remove burrs and other surface flaws, and control the surface friction. In limited cases some of these techniques can be used to restore original dimensions to salvage or repair an item.
