The final surface is a variety of industrial processes that alter the surface of an item created to reach a particular property. The finishing process can be used to: improve appearance, adhesion or wettability, solderability, corrosion resistance, tarnish resistance, chemical resistance, wear resistance, hardness, modify electrical conductivity, remove burrs and other surface defects, and control surface friction. In some cases, some of these techniques can be used to restore the original dimension to save or repair items. Unfinished surfaces are often called mill finish .
The surface finishing process can be categorized by how they affect the workpiece:
- Delete or reshape finishing
- Add or change end
The mechanical process can also be categorized together because of the ultimate surface end similarity.

Mechanical finishing process includes:
The use of abrasives in metal polishing results in what is considered a "mechanical solution".
Metal end tag
Also known as grinding, roughing or coarse grinding. This final result is crude and is usually the initial solution applied before the manufacturing. An example would be to grind the gate from casting, deburring or disposing of excessive weld material. It is rugged in appearance and applied with a 36-100 abrasive grit.
When finished set as # 3, the material is polished to 60-80 grit uniform.
Also known as brushed, directional or satin finish. An architectural finish # 4 is marked by a smooth polishing grit line that is uniform and directed in appearance. It is manufactured with metal polish with a 120-180 grit belt or completed wheel and then softened with 80-120 grit of greaseless compound or medium non woven abrasive belt or pad.
The finish is commonly used for the medical and food industries and is almost exclusively used in stainless steels. This final result is much better than the final result of architecture # 4. This final result improves the physical appearance of the metal as well as improves the benefits of sanitation. One is very careful to remove surface defects in metals, such as holes, which allow bacteria to grow. Dairy # 4 or sanitary napkins are manufactured with polish with a 180-240 grit belt or a softened wheel folding with 120-240 grit greaseless compound or fine non woven abrasive belt or pad.
Also known as fine satin. This final result is produced by polishing with a 220-280 wrinkled belt or wheel that is softened with a 220-230 berkeratin or a very fine abrasive non woven belt or pad. The polishing line will be soft and less bouncing than the finish of architecture # 4.
Completed # 7 is produced by polishing with a 280-320 belt or wheel and sisal buffing with cut and color compounds. This is a semi-bright result that still has some polishing lines but will be very boring. The carbon and iron steels are generally polished until the end of # 7 before chrome plating. Completed # 7 can be made light by buffing colors with dye compounds and cotton buffs. This is usually applied to keep the cost of polishing when the parts should be shiny but not perfect.
Also known as mirror results. This final result is produced by polishing at least 320 grit belt or wheel wheel. Care will be taken to ensure all surface defects are removed. The sisal part is rubbed and then the color is rubbed to achieve the final result of the mirror. The quality of the finish depends on the quality of the polished metal. Some alloys of steel and aluminum can not be brought into the mirror. Casting that has a slag or hole will also be difficult, if not impossible, to polish to # 8.
