1.What is Aluminum CNC Machining?
Aluminum CNC machining involves shaping aluminum alloys into functional components using computer-controlled milling, turning, or drilling. Renowned for its lightweight properties, corrosion resistance, and excellent thermal conductivity, aluminum is ideal for applications demanding durability and precision. Common uses include automotive brackets, electronic housings, and medical device components.
2.Aluminum CNC Machining Processes
5-Axis CNC Milling: Ideal for complex geometries like heat sinks or engine blocks, achieving tolerances up to ±0.005 mm. Our HAAS and Okuma machines ensure precision in 3D contours.
CNC Turning: Perfect for cylindrical parts such as bushings and valve stems, with Swiss-type lathes handling high-tolerance designs.
Wire EDM: For intricate cuts in thin-walled components without heat distortion, commonly used in electronics and medical devices.
Surface Finishing: Options include hard anodizing (for wear resistance) and electropolishing (to enhance conductivity).
3.Common Aluminum Alloys for Machining
6061-T6: High strength-to-weight ratio for structural components like automotive frames.
