Understanding Aluminum CNC Machining

CNC machining aluminum plates is one of the most common manufacturing processes across industries due to aluminum's excellent machinability, strength-to-weight ratio, and corrosion resistance. As a CNC machining expert at EMAR, we specialize in transforming aluminum plates into precision components for aerospace, automotive, electronics, and more.

Key Methods for CNC Machining Aluminum Plates

There are several fundamental methods we employ when working with aluminum plates:

• Milling: Our 3-5 axis CNC milling machines create complex geometries with tight tolerances (±.005mm)
• Turning: For cylindrical parts, our CNC lathes deliver exceptional surface finishes
• Drilling & Tapping: Precision hole-making with optimized tool paths to prevent burring
• Contouring: Creating intricate 2D and 3D profiles from aluminum plate stock

Material Considerations

We work with various aluminum grades, each offering unique benefits:

• 6061-T6: Most common, excellent all-around properties
• 7075: Higher strength for aerospace applications
• 5052: Superior corrosion resistance
• 2024: High fatigue resistance
