Aluminum Parts CNC Machining Process

As a professional CNC Machining service provider, EMAR specializes in delivering high-precision aluminum components for industries ranging from aerospace to automotive. This article delves into the critical aspects of aluminum CNC machining, addressing key concerns for procurement managers and engineers.

Understanding Aluminum CNC Machining

Aluminum is one of the most machinable metals due to its excellent strength-to-weight ratio and corrosion resistance. The CNC machining process for aluminum involves computer-controlled milling, turning, or drilling to create complex geometries with tight tolerances (typically ±.005 inches).

Key Process Steps

1. Material Selection: Choosing the right aluminum alloy (6061, 7075, etc.) based on application requirements.
2. CAD/CAM Programming: Converting 3D models into machine instructions.
3. Precision Machining: Using advanced CNC mills/lathes with high-speed spindles (up to 20,000 RPM).
4. Surface Finishing: Options include anodizing, powder coating, or chemical conversion.
