What Is CNC Machining?
CNC machining (Computer Numerical Control machining) is a subtractive manufacturing process in which pre-programmed computer software controls machine tools to remove material from a solid workpiece. CNC machining is widely used to produce high-precision parts with consistent quality, repeatability, and excellent surface finishes. Compared with manual machining, CNC machining offers:

Our experienced professionals specialize in product surface treatment.
| Name | Description | Materials | Color | Texture | More |
|---|---|---|---|---|---|
Brushing |
Brushing is a surface treatment that grinds the workpiece to create decorative lines, enhancing its aesthetic appeal. | Aluminum, Brass, Stainless Steel, Steel, ABS,etc | N/A | Satin | |
Sand Blast |
Sandblasting uses high-speed sand flow to clean and roughen surfaces, ensuring desired cleanliness and texture. | All Metal Materials, Plastic | N/A | Matte | |
Tumbling |
Tumbling smooths surfaces, deburrs edges, and enhances uniformity by rotating materials with abrasive media. | All Materials | N/A | Smooth, Matte | |
Polishing |
Polishing removes imperfections, smooths surfaces, and enhances appearance, creating a shiny, reflective finish. | All Materials | N/A | Smooth | |
Anodizing |
Anodizing enhances aluminum by adding a protective layer for improved corrosion resistance, hardness, and appearance. | Aluminum, Titanium | Clear, Yellow, Green, Blue, Black, etc |
Smooth, matte finish. | |
Painting |
Mount the product on a rotating bracket, secure it on the assembly line, and apply paint evenly. This improves texture but may increase scratch susceptibility. | All Materials | Clear, Yellow, Green, Blue, Black, Multiple | Gloss, semi-gloss, flat, metallic, textured | |
Black Oxide |
Black oxide forms a protective film that enhances corrosion resistance, appearance, and reduces light reflection, ideal for steel and stainless steel. | Steel, Stainless Steel | Black | Smooth, matte | |
Electroplating |
Electroplating enhances function, aesthetics, and corrosion resistance, widely used in industries like automotive for chrome-plated steel parts. | Aluminum, Steel, Stainless Steel | Gold, Silver, Nickel, Copper, Brass, Zinc, Chrome | Smooth, glossy finish | |
Powder Coating |
Powder coating electrostatically applies dry powder to metal, then cures it with heat or UV light for a durable, attractive finish. | Aluminum, Stainless Steel, Steel,etc | Custom | Gloss, matte or semi-gloss | |
Alodine |
An alodine finish forms a thin protective coating on aluminum, preventing corrosion and serving as a paint primer. | Aluminum, Stainess Steel | Clear, Gold | As machined | |
Passivation |
Passivation improves stainless steel's corrosion resistance by immersing it in an acid solution, removing contaminants, and forming a protective oxide layer. | Stainess Steel | N/A | Matte | |
Electroless Plating |
Electroless plating deposits metal onto a substrate through a chemical reaction, creating a uniform, adherent coating without the need for an external electrical current. | Metal, Plastic | Gold, Silver, Nickel, Copper, Brass, Zinc, Chrome | Smooth, glossy finish |
