Surface Finishes for CNC Turning
CNC machining leaves visible tool marks during the process of removing portions of the block's surface to create desired shapes. If you don't want as-machined parts, select a surface finishing for your custom parts. At NOBLE, we offer several common surface finishes that help improve functionality and aesthetics.
Name | Description | Materials | Color | Texture | |
---|---|---|---|---|---|
![]() |
Anodizing | Anodizing improves corrosion resistance, enhancing wear resistance and hardness, and protecting the metal surface. Widely used in mechanical parts, aircraft, and automobile parts, precision instruments, etc. | Aluminum | Clear, black, grey, red, blue, gold. | Smooth, matte finish |
![]() |
Sand Blasting | Sand blasting results in parts with a smooth surface with a matte texture. Used mainly for visual applications and can be followed by other surface treatments. | ABS, Aluminum, Brass | N/A | Matte |
![]() |
Powder Coating | Powder coating is a type of coating that is applied as a free-flowing, dry powder. Unlike conventional liquid paint which is delivered via an evaporating solvent, powder coating is typically applied electrostatically and then cured under heat or with ultraviolet light. | Aluminum, Stainless Steel, Steel | Black, any RAL code or Pantone number | Gloss or semi-gloss |
![]() |
Electroplating | Electroplating can be functional, decorative or corrosion-related. Many industries use the process, including the automotive sector, in which chrome-plating of steel automobile parts is common. | Aluminum, steel, Stainless Steel | N/A | Smooth, Glossy finish |
![]() |
Polishing | Polishing is the process of creating a smooth and shiny surface, either through physical rubbing of the part or by chemical interference. The process produces a surface with significant specular reflection, but in some materials is able to reduce diffuse reflection. | Aluminum, Brass, Stainless Steel, Steel | N/A | Glossy |
![]() |
Brushing | Brushing is a surface treatment process in which abrasive belts are used to draw traces on the surface of a material, usually for aesthetic purposes. | ABS, Aluminum, Brass, Stainless Steel, Steel | N/A | Satin |

5 Steps for Producing CNC Turned Parts
- Prepare the G-Code
Convert your 3D CAD model into a G-code file using CAM software. This code provides the CNC lathe with precise machining instructions.
- Load the Material
Select a solid bar of plastic or metal and load it into the CNC lathe, ensuring it's securely clamped to avoid movement during machining.
- Secure the Workpiece
The chuck grips the workpiece as the spindle rotates, ensuring stability and precision throughout the process.
- Engage the Cutting Tool
Once the spindle reaches speed, a stationary cutting tool contacts the rotating workpiece, removing material according to the G-code until the desired shape is achieved.
- Finalize the Part
After machining, cut the finished part from the raw stock. Apply finishing processes like deburring or polishing to enhance appearance and durability before delivery.
By following these steps, we ensure an efficient CNC turning process that produces high-quality, precision-engineered parts. For more information about our CNC turning services, please contact us!
