The five-axis machining center is a high-precision, high-efficiency machining equipment that can operate on five axes (usually three linear axes of X, Y, and Z and two rotary axes) to process complex parts. The surface treatment after five-axis machining mainly includes the following:

Mechanical treatment:

Grinding: Use a grinder to polish the machined surface to obtain higher precision and smoother surface.

Polishing: Improve the surface finish and aesthetics through mechanical polishing or manual polishing.

Deburring: Remove burrs generated during the machining process to ensure the dimensional accuracy and appearance of parts.

Chemical treatment:

Pickling: Remove the oxide layer and dirt on the surface through pickling to prepare for subsequent processing.

Passivation: Form a protective film on the surface of materials such as stainless steel to improve corrosion resistance.

Electrochemical treatment:

Electrolytic polishing: Polish the metal surface using the principle of electrolysis to obtain a uniform and bright surface.

Anodizing: Mainly used for aluminum and its alloys to form an oxide film to improve corrosion resistance and hardness.

Coating treatment:
Electroplating: A layer of metal is plated on the surface of the part, such as nickel plating, chrome plating, zinc plating, etc., to improve wear resistance and corrosion resistance.
Spraying: Including painting, powder spraying, etc., providing different colors and surface effects.
Vacuum coating: Such as physical vapor deposition (PVD), chemical vapor deposition (CVD), etc., to form a wear-resistant and corrosion-resistant film on the surface.
 

Heat treatment:
Quenching, tempering, annealing: By changing the internal structure of the metal, the hardness and wear resistance of the parts are improved.
 

Laser processing:
Laser engraving: Carve text, patterns or marks on the surface of the part.
Laser cladding: A layer of material is clad on the surface of the part to repair or improve the surface properties.
The choice of surface treatment method depends on factors such as the material of the part, design requirements, application environment, and cost budget. Surface treatment after five-axis machining is crucial to improving the quality and service life of the parts.
