A reliable CNC milling manufacturer in China, providing high-quality precision CNC milling services for customers across the United States and Europe. We specialize in producing custom CNC milled parts with tight tolerances, consistent quality, and fast global delivery.
Our experienced engineering team works closely with customers to optimize part designs for manufacturability (DFM), reduce machining costs, and ensure stable performance from prototype development to high-volume production.
Whether you need rapid prototypes, low-volume batches, or long-term production supply, MW+ delivers flexible and dependable CNC milling solutions tailored to your project requirements.
CNC milling is a computer-controlled machining process that removes material from a solid block using high-speed rotating cutting tools. Programmed toolpaths enable the creation of precise features such as:
- Slots, pockets, and cavities
- Precision holes and threaded features
- Complex contours and 3D surfaces
- Multi-face and multi-angle geometries
CNC milling is widely used for aluminum, stainless steel, titanium, copper alloys, and engineering plastics. Its excellent accuracy, repeatability, and scalability make it ideal for industries requiring high precision and consistent performance.
High precision available based on material and geometry requirements.

CNC Milling Design Guidelines (DFM Tips)
Following proper design practices improves machining efficiency, reduces costs by up to 30%, and ensures better part quality. Our engineering team provides Design for Manufacturability (DFM) support.
Minimum Wall Thickness
Aluminum: ≥ 0.8–1.0 mm | Steel: ≥ 1.5 mm | Plastics: ≥ 1.5–2.0 mm
Thin walls may cause vibration, deformation, or dimensional instability during machining.
Hole Depth Recommendations
Maximum depth: 4–6 × hole diameter
Deep holes increase machining time and tool wear by up to 40%. For deeper holes, consider specialized drilling techniques or redesign.
Corner Radius Guidelines
Internal corners: Should include a radius (≥ 0.5–1.0 mm)
Sharp internal corners require special tools and increase machining costs by 25–50%. Adding radii improves tool life and part strength.
Tolerance Best Practices
Standard tolerance: ±0.01 mm
Tight tolerances (±0.005mm) should only be specified where functionally necessary to reduce machining cost. Each additional decimal place increases cost by 20–30%.
