The main finishing processes are:

• Polishing, which provides a very smooth and shiny appearance or very thin surface finishes.
• The principle is to remove small bits of material, by mechanical abrasion using very fine millstones or liquids with fine abrasives.
• In contrast, micro beading gives a "rougher" appearance.
• Very hard, small beads (sand or glass) are projected at high speed to modify the treated surface.
• Tribofinishing is a form of polishing which gives a very thin surface gloss finish and also rounds off any sharp edges.
• Reproduction, in a workshop, of a well-known natural process which is the abrasion of workpieces in a liquid and abrasive mixture which is stirred over many hours.
• Engraving, which is used for decoration, identification or traceability.
• Engraving is generally performed with a laser and can be superficial or very deep.
• Deposits of various forms such as paints or lacquers, PVDs, etc. They are used for decoration but also to provide specific properties, such as making a ceramic conductive in certain places, for example.
