Custom 5-Axis CNC Machining for Complex Aluminum Stainless Steel Brass Parts
Product Spotlights
Since 1990, Ningbo Changfeng Mechanical Factory has delivered precision manufacturing solutions to global clients across North America, Europe, Asia and beyond. Our custom 5-axis CNC machining services transform aluminum, stainless steel, and brass into complex functional components with micron-level accuracy. With over three decades of expertise and US$10-50 million annual export volume, we provide seamless production from prototype to bulk orders while reducing your assembly costs by up to 40%.
Key technical advantages include:
- Simultaneous 5-axis capability enables undercut machining and compound angles in single setup
- Material-specific toolpaths for optimal surface integrity on aluminum alloys (6061, 7075), stainless (303, 316), and brass
- Advanced CAM programming for thin-wall structures (
| Parameter | Capability |
|---|---|
| Max Part Dimensions | 800 x 500 x 400 mm |
| Standard Tolerances | ISO 2768 medium |
| Surface Roughness | Ra 0.4 - 3.2 μm achievable |
Clients in medical and aerospace sectors benefit from our first-article inspection protocols and digital twin verification. For automotive applications, we achieve 15% weight reduction through topology optimization without compromising structural integrity. All components undergo coordinate measuring machine (CMM) validation with comprehensive reports available.
With established supply chains to 15 global markets including Western Europe and North America, our Ningbo-based facility guarantees 30-day lead times for most orders. Backed by US$10-50 million annual export volume since 1990, we maintain inventory buffers for urgent replacements and provide DFM feedback within 24 hours of design submission.
