High Precision CNC Parts Aluminum Anodizing Machine CNC Milling And Turning Parts Manufacturing Services

Surface treatment after CNC turning can improve the appearance, dimensional accuracy, surface roughness, corrosion resistance and other functional properties of the part. The following are some common surface treatment methods after CNC turning:

Grinding:

Fine grinding: used to improve the dimensional accuracy and surface finish of the part.
Polishing: Improve the smoothness and reflectivity of the surface by using polishing wheels and abrasives.

Deburring:
Manual deburring: Use tools to manually remove burrs from the part.
Mechanical deburring: Use deburring machines and deburring media to automatically remove burrs.

Electrochemical treatment:
Electroplating: Deposit a layer of metal on the surface of the part to improve corrosion resistance and appearance.
Chromium plating: Plate a layer of chrome on the surface of the part to improve hardness and corrosion resistance.
Nickel plating: Provides anti-corrosion and decorative surfaces.

Anodizing:
Applicable to aluminum and aluminum alloys, forming an oxide film to improve corrosion resistance and hardness.

Passivation:
Commonly used for stainless steel, forming a protective film to improve corrosion resistance.

Coating:
Painting: Provides color and protection.
Powder coating: forms a uniform powder coating to improve corrosion resistance and appearance.

Heat treatment:
Quenching: improves the hardness and wear resistance of the material.
Tempering: reduces internal stress and improves toughness and stability.

Laser treatment:
Laser engraving: engraves patterns or text on the surface of the part.
Laser quenching: local hardening of the material surface.

Ultrasonic cleaning:
Used to remove oil, dust and other contaminants from the surface of the part.

Chemical treatment:
Chemical conversion treatment: such as phosphate treatment, provides a base coating for the metal to enhance the adhesion of the coating.
The choice of surface treatment method depends on the end use of the part, the required physical and chemical properties, cost and production cycle. Different surface treatment methods can be used alone or in combination to achieve the best surface quality and performance.

We accept all kinds of parts customization, a variety of materials to choose from: iron, aluminum, copper, stainless steel, etc., a variety of surface treatment options to choose from: polishing, coating, frosted surface, etc., as long as you provide drawings, samples and customized quantities, we can give you a preferential price.
