What Is CNC Aluminum Machining?
Aluminum CNC machining refers to the process of shaping aluminum workpieces into precise parts using computer-controlled cutting tools. This includes CNC milling, CNC turning, drilling, and tapping. CNC aluminum machining offers high accuracy, repeatability, and scalability, making it ideal for complex components with tight tolerances.
The process is suitable for a wide range of aluminum grades such as 6061-T6, 7075, and 5052, depending on the required strength, weight, and corrosion resistance. With the help of multi-axis CNC equipment, aluminum parts can be machined into intricate shapes for critical applications.
