CNC Machining FAQs
What is CNC Machining?
CNC (Computer Numerical Control) machining is an automated manufacturing process that precisely cuts and shapes materials using computer-controlled tools. It ensures high accuracy, repeatability, and efficiency, making it ideal for metal and plastic parts in various industries.
What’s the difference between CNC machining and 3D printing?
CNC machining is a subtractive manufacturing process, where material is removed to create parts, suitable for high-precision metal and plastic machining.
3D printing is an additive manufacturing process, building up layers of material, ideal for rapid prototyping and complex geometries.
| Feature | CNC Machining | 3D Printing |
|---|---|---|
| Material | Suitable for metals, plastics, and composites | Mainly for plastics, some metals |
| Precision | High precision, typically ±0.01mm | Lower precision, usually ±0.1mm |
| Strength | High mechanical strength, ideal for functional parts | Suitable for prototypes, but weaker structural strength |
| Production Speed | Best for batch production | Ideal for single or small-batch manufacturing |
| Cost | Higher per-unit cost, but cost-effective for mass production | Lower cost for small batches, but material costs may be higher |
CNC Machining or 3D Printing, which one to choose?
CNC machining is ideal for high-precision, strong functional parts, while 3D printing works well for rapid prototyping and complex designs.
How much does CNC machining cost?
The cost of CNC machining depends on several factors, including:
- Material selection (Aluminum, steel, titanium—each with different costs)
- Part complexity (The more intricate the design, the longer the machining time)
- Production quantity (Larger batches reduce unit costs)
- Surface finishing (e.g., anodizing, electroplating)
Generally, the more complex the part structure and the higher the precision requirements, the longer the machining time, leading to higher costs.

What is the minimum tolerance for CNC machining?
CNC machining tolerances depend on machine accuracy, material properties, and the machining process.
Tolerance Levels:
- Standard CNC machining: ±0.05mm
- High-precision CNC machining: ±0.01mm
- Ultra-precision machining (aerospace, medical): ±0.005mm or smaller
Â
Factors Affecting Tolerance:
- Thermal expansion – Some metals deform under heat
- Machine precision – 5-axis CNC machines are generally more accurate than 3-axis
- Tool wear – Long-term use may reduce accuracy

What types of products are suitable for CNC machining?
CNC machining is widely used for high-precision, high-strength parts, including:
- Industrial machinery: Gears, fixtures, precision components
- Automotive: Engine parts, chassis components
- Aerospace: Structural brackets, turbine blades
- Medical devices: Implants, surgical tools
- Electronics: Heatsinks, enclosures
What surface finishing options are available for CNC machining?
CNC machined parts can undergo various surface treatments to enhance durability, appearance, and functionality:
- Anodizing – Ideal for aluminum, improves corrosion resistance
- Electroplating – Nickel, zinc, and other coatings for wear resistance
- Polishing – Creates a mirror finish, often used for medical devices
- Passivation – Enhances corrosion resistance, especially for stainless steel
- Nitriding – Hardens the surface, improving wear resistance
- Black Oxide – Enhances oxidation resistance for steel parts
