Custom Precision CNC Machining Surface Finishing Options
We provide a wide range of surface finishing solutions to improve the performance and aesthetics of CNC machined parts. These finishes enhance properties such as texture, hardness, smoothness, chemical resistance, and corrosion resistance. In addition to improving functionality, they effectively conceal tool marks left by the machining process, resulting in a clean, high-quality appearance. Below are some of the most commonly used finishing options:
As Machined
CNC machined metal, natural color, no need for any surface treatment.
Sand Blasting
Cleans the CNC Machining Parts surface and increases the roughness to improve the adhesion of the coating.
Electropolishing
Smooths the surface through electrochemical dissolution, suitable for parts with complex shapes.
Anodizing + Dyeing
Used for surface treatment of metal materials such as aluminum alloy to enhance their decorative properties and corrosion resistance.
Anodizing
Applicable to aluminum-titanium-magnesium alloys, forming an oxide film to enhance corrosion resistance and hardness, such as hard oxidation (Type III) for aviation parts.
Passivation
Make the surface of CNC machined metal parts inactive, thereby slowing down the corrosion rate of the metal.
Polishing
Polishing CNC machined parts improves surface smoothness, removes tool marks, enhances assembly fit, increases corrosion and wear resistance, and elevates overall appearance.
Brushing
Brushing forms linear textures and is used for electronic product housings.
Powder Coating
Curing after electrostatic spraying provides a variety of colors and wear-resistant surfaces.
Laser Marking
Use laser to engrave information such as marks, text, patterns, etc. on the surface of the material onto the object. Applicable to metal, plastic, ceramic, glass, etc.
