Our CNC Machining Capabilities
Metal CNC Machining Products
Metal CNC Product Processing: We prepare the raw materials and set up machine programs. This is followed by rough machining, fine machining, and second-side machining. The process is wrapped up by completing machining, and 3D inspection. We can produce 200 pieces in 7 days.
Machining Precision: ±0.1mm/100mm
Maximum Part Size: 2000×800×580mm
Materials: Aluminum alloy, titanium alloy, copper (purple luster), stainless steel, zinc alloy, magnesium alloy
Plastic CNC Machining Products
Plastic CNC Product Processing: We fix the raw materials, set up machine programs, rough machine the first side, and fine machine of the first side. Then, we rough machine the second side and fine machine the second side. Finally, we complete machining, conduct manual finishing, and complete both manual inspection and 3D inspection. We can produce 200 sets in 3 days.

What are the Common Surface Finish Options?
Surface finishes refer to the process of applying treatments to the surface after the manufacturing process to change the appearance, hardness, surface roughness, and other properties. Common surface finishes for CNC include as-machined, polishing, bead blasting, painting, plating, anodizing, silk screen, and powder coating.
Standard Surface Finishing for Plastic Products
Machining Precision: ±0.05mm/100mm
Surface Finishing Options: Standard surface finishing services for plastics include grinding, polishing, electroplating, wire drawing, spraying painting, laser engraving, and screen printing. Additionally, transparent PMMA and transparent PC finishes can achieve a fully transparent effect by spraying transparent oil. Spraying options include normal gloss and matte oil, spraying with sand, and rubber oil (UV gloss and matte oil, which provides stronger protection).
Standard Surface Finishing for Metal Products
Machining Precision: ±0.05mm/100mm
Surface Finishing Options: Deburring, grinding, polishing, sandblasting, oxidation, electroplating, black oxide, wire drawing, screen printing, laser engraving, spraying metal paint, spraying powder, chromate, spraying rubber paint, heat treatment, passivation, etc.
What are the Benefits and Limitations of Using CNC Machining?
Advantages
- Precision: CNC machines can produce highly precise and accurate parts with tight tolerances, leading to high-quality surface finish products.
- Repetitive Tasks: CNC machining is ideal for repetitive tasks, as it ensures consistent quality across multiple parts or components.
- Various Production Volumes: CNC machining is suitable for prototyping, low-volume and large-scale manufacturing.
- Flexibility and Versatility: CNC machines can be programmed to produce a wide range of shapes and designs, from simple to highly complex designs, making them suitable for diverse manufacturing needs.

CNC Machining Services FAQs
What is CNC Machining?
Computer numerical control (CNC) machining is a manufacturing process that dictates the movement of factory tools and machinery with pre-programmed computer software. This process can control a variety of complex machines, such as CNC millings, CNC lathes, CNC plasma cutting machines, CNC electric discharge machines (EDM), and printed circuit board fabrication 3D printers. It can produce parts and components with complex geometries and high accuracy for prototyping and low-to-high volume end-use.
CNC Machining vs. 3D Printing: What are the Differences?
CNC machining and 3D printing are both manufacturing technologies, but they have some key differences.
| CNC Machining | 3D Printing |
|---|---|
| Subtractive Manufacturing: It cuts away material from solid blocks to create the final shape | Additive Manufacturing: It adds materials layer by layer to form final products based on digital files |
| CNC machining can process various materials, including metals, plastics, wood, stone, and composite materials | Limited layering materials such as plastics (like PLA, ABS), resins, metals (like stainless steel, titanium), and ceramics |
| High precision and excellent surface finish | Lower accuracy and rougher surface finish compared to CNC machining |
| Suitable for both prototyping and large-volume production | Suitable for prototyping and producing small batches or personalized parts |
| Widely used in various industries such as aerospace, automotive, machinery, and mold making | Can manufacture models with complex shapes and unique structures, making it suitable for fields such as health care and artistic design |
| Higher initial setup costs but lower per-unit costs | Lower initial setup costs but higher per-unit costs |
However, the choice between CNC machining vs. 3D printing ultimately depends on your specific project requirements, such as component complexity, volume, and material properties.
If you’re unsure about whether to choose CNC machining or 3D printing for your project, reach out to us. We’ll help assess your specific requirements and provide expert advice on the best manufacturing method for your needs.
