Aluminum CNC Machining Services
Manufacturer of custom aluminum parts
Aluminum is most used materials in CNC machining, thanks to its excellent strength-to-weight ratio, corrosion resistance, and ease of machinability.
At RJC, we offer custom aluminum parts from rapid prototyping, low volume production, and mass production.
Our CNC Aluminum Machining Capabilities
We offer comprehensive CNC machining services for aluminum, ensuring tight tolerances and smooth surface finishes:
- Processes: CNC milling, CNC turning, 5 Axis CNC machining
- Tolerance: Up to ±0.005mm for critical dimensions
- Part Size: Up to 1200 × 800 × 500mm
- Volume: 1 to 10,000+ parts
- Lead Time: 3–5 days for prototypes; 7–12 days for production
All parts are inspected using precision metrology tools and supported by engineer-led design for manufacturability (DFM) feedback.
