CNC Machining Precision Aluminum Parts

As a leading CNC Machining service provider, EMAR specializes in manufacturing high-precision aluminum components for industries ranging from aerospace to electronics. This article explores the technical process, quality control measures, and why precision matters in aluminum part fabrication.

Why Choose CNC for Precision Aluminum Parts?

Aluminum's excellent machinability and strength-to-weight ratio make it ideal for precision components. CNC technology achieves tolerances as tight as ±.005mm, with surface finishes down to Ra .4μm. Our 5-axis machines at EMAR can create complex geometries impossible with conventional machining.

The Precision Machining Process

1. Material Selection: We use 6061, 7075, and other aerospace-grade aluminum alloys

2. CAD/CAM Programming: Our engineers optimize tool paths for precision and efficiency

3. Machining: Multi-axis CNC centers perform milling, drilling, and tapping operations

4. Quality Inspection: CMM and optical comparators verify dimensional accuracy
