5-Axis CNC Machined Stainless Steel & Aluminum Mechanical Parts
Product Spotlights
Established in 1990, Ningbo Changfeng Mechanical Factory is a trusted manufacturer specializing in high-precision machined components. With an annual export value ranging between US$10 Million and US$50 Million, we serve diverse global markets including North America, Europe, Asia, and beyond. Our advanced 5-axis CNC machining capabilities enable us to produce exceptionally complex and accurate stainless steel and aluminum mechanical parts, meeting the stringent demands of modern industries.
Unmatched Precision & Complexity: Our state-of-the-art 5-axis CNC machining centers allow for simultaneous movement along five different axes. This capability is crucial for manufacturing parts with intricate geometries, undercuts, and compound angles that are impossible or inefficient with 3-axis machines. Benefits include:
- Reduced setup times and increased production efficiency.
- Superior surface finishes and exceptional dimensional accuracy (±0.01mm achievable).
- Ability to machine complex contours and features in a single setup, minimizing errors.
- Optimized tool paths for longer tool life and better chip evacuation.
Material Expertise: We expertly machine a range of materials, focusing on:
- Stainless Steel (e.g., 303, 304, 316, 17-4PH): Chosen for its excellent corrosion resistance, high strength, and durability in demanding environments (chemical, marine, food processing).
- Aluminum (e.g., 6061, 7075): Selected for its lightweight properties, good strength-to-weight ratio, excellent machinability, thermal conductivity, and corrosion resistance (ideal for aerospace, automotive, robotics).
Key Technical Specifications & Capabilities:
| Feature | Capability |

Frequently Asked Questions (FAQ):
-
Q: What is the typical lead time for custom 5-axis CNC parts?
A: Standard lead times range from 2 to 4 weeks, depending on part complexity, quantity, and required secondary operations. Prototyping can often be expedited. -
Q: What materials do you offer besides Stainless Steel and Aluminum?
A: While SS and Al are our core focus, we also machine brass, copper, titanium, and various engineering plastics (like PEEK, Delrin). Inquire about specific material needs. -
Q: Do you provide material certifications?
A> Yes, material certifications (Mill Test Reports - MTRs) are available upon request for traceability and quality assurance. -
Q: What file format is best for submitting my part design?
A> We prefer 3D solid models in STEP (.stp) or IGES (.igs) format. 2D drawings in PDF or DWG/DXF are also helpful for critical dimensions and tolerances. -
Q: Can you handle both prototyping and large-volume production?
A> Absolutely. We are equipped for low-volume, high-mix prototyping runs as well as high-volume production batches, offering scalability for your project needs. -
Q: What surface finishing options do you provide for Aluminum parts?
A> Common options include bead blasting, anodizing (clear, black, color), powder coating, chemical film (chromate conversion), and painting. We can advise on the best finish for your application. -
Q: How do you ensure the dimensional accuracy of complex parts?
A> We utilize advanced CMM (Coordinate Measuring Machine) inspection, laser scanners, and precision gauges to verify critical dimensions and geometries against your CAD models and drawings throughout the machining process. -
Q: Is there a minimum order quantity (MOQ)?
A> Our MOQ is flexible. We work with clients on prototypes (even single pieces) and small batches, scaling up seamlessly to larger production volumes.
