Several Common Machining Surface Treatment Methods

Grinding: Using grinding processes to remove surface irregularities and burrs, improving surface roughness, commonly used for precision machining and finishing of metal parts.

Polishing: Through grinding or polishing processes, the surface is smoothed and gloss is increased, suitable for parts requiring high surface smoothness and aesthetics, such as jewelry, automotive parts, etc.

Sandblasting: Using high-pressure airflow to blast sand particles onto the surface, creating a rough surface texture, commonly used to improve surface roughness and increase adhesion, such as pre-treatment before painting, increasing coating adhesion, etc.

Anodizing: Forming an oxide layer on the metal surface to improve corrosion resistance, hardness, and surface color, commonly used for aluminum alloy parts.

Plating: Covering the metal with a layer of metal or non-metallic surface treatment method, commonly used plating includes chrome plating, nickel plating, zinc plating, etc., used to improve corrosion resistance, increase hardness, beautify the surface, etc.

Painting: Spraying paint onto the surface of the part to form a protective film, improving surface corrosion resistance, aesthetics, and color selectivity.

Heat Treatment: By controlling the heating and cooling process of the material, its structure and performance are changed to improve hardness, strength, wear resistance, etc.

Chemical Treatment: Using chemical solutions or etchants to treat the surface, such as acid pickling, degreasing, rust removal, etc., to remove surface oxide layers, dirt, and defects.

Choosing the appropriate surface treatment method depends on factors such as the material, application, environmental conditions, cost, and processing complexity of the parts, to meet the performance and aesthetic requirements of the parts.
