CNC Machining Surface Finishes
CNC machining inevitably leaves behind visible tool marks as it removes portions of the block’s surface to shape the desired parts. If you seek to avoid the appearance of as-machined parts, opting for a surface finishing is essential for your custom components. At GreatLight, we provide a range of common surface finishes tailored to enhance both the functionality and aesthetics of your parts.
| 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. |
 | Bead Blasting | Bead 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, Stainless Steel, Steel | 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 can 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 |

CNC Machining FAQs
CNC Machining, or Computer Numerical Control Machining, is a manufacturing technique where computer-controlled devices are used to remove layers from a material, creating detailed parts or components. Through a combination of tooling and precise machine movement, it produces parts to exact specifications.
Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Nibh praesent tristique magna sit amet purus. Odio ut sem nulla pharetra diam sit amet nisl. Facilisi cras fermentum odio eu feugiat. Aenean
CNC Machining offers unparalleled precision and repeatability, making it a top choice for industries requiring intricate parts. Its ability to handle a variety of materials, from metals to plastics, combined with fast production times and consistent quality, makes it an essential method in modern manufacturing.
The CNC machining process begins by designing a part in CAD software. This design is then converted into a set of machine commands using CAM software. The CNC machine reads these commands to precisely cut and shape the material, producing a finished part that matches the digital design.
3D printing is an additive manufacturing method, building parts by depositing material layer by layer. In contrast, CNC machining is a subtractive method, starting with a solid block of material and removing sections until the desired part is achieved. While 3D printing is often favored for complex geometries and rapid prototyping, CNC machining excels in durability, precision, and material versatility.
Our engineering and sales teams will provide one-on-one quote support for your project. Typically, for similar parts, CNC lathes cost 15% less to machine than standard 3-axis CNC milling. In contrast, the cost of 5-axis machining increases, continuous 5-axis CNC milling typically costs over 20% higher than an indexed 5-axis machine (also referred to as 3+2 milling), and about double that of a standard 3-axis mill. To achieve the most cost-effective CNC machined parts, larger production runs are recommended to spread the cost of machine setup.
Maximum Dimensions (3-axis milling): 1270×508×635 (mm).
Maximum Dimensions (5-axis milling): 450×700×400 (mm), Worktable Diameter Φ400 mm.
Once the machining process is complete, the CNC parts surface will have slight visible tool marks, called “as-machined” or “as-milled” surface finish. Machined surface roughness (Ra) is standardized at 1.6-3.2 μm, and surface finish requirements can be increased to 0.8-1.6 μm or higher at 0.2-0.8 μm, however, this will require more operating time and higher costs.
