Precision Metal Fabrication Using 5-Axis CNC Milling

CNC Milling Parts Production Process

1. CAD/CAM Programming (3D modeling and tool path optimization)
2. Material Preparation (selecting suitable metals or engineering plastics)
3. Precision Machining (rough machining → semi-precision machining → precision machining)
4. Post Processing (deburring, anodizing, sandblasting, etc.)

The key to Precision Milling Service is minimizing clamping operations and ensuring consistent machining quality.

Equipment Selection & Processing Capability

Different industries require tailored equipment solutions:

• 3-Axis CNC Milling Machine: Ideal for simple geometries and cost-effective production
• 5-Axis CNC Milling: Capable of machining complex surfaces such as impellers and turbine blades
• High-Speed Milling Machine: Optimized for efficient cutting of soft metals like aluminum and copper

For example, a metal fabrication service provider reduced turbine housing machining time by 40% after implementing 5-axis machine tools.

Processing Range & Material Adaptability

CNC milling services support a wide range of materials:

• Metal Categories: Aluminum alloy, stainless steel, titanium alloy
• Plastic Categories: PEEK, Nylon, ABS
• Composite Materials: Carbon Fiber Reinforced Polymer (CFRP)

Part sizes can range from micro components (<1mm) to large structural frames (>2m).

Surface Treatment & Functional Optimization

Based on application needs, high-precision CNC-machined parts can undergo:

• Anodizing (enhances corrosion resistance of aluminum alloys)
• Electroplating (improves conductivity or wear resistance)
• Shot Peening Strengthening (extends fatigue life)

By optimizing processes and equipment configurations, custom metal fabrication services achieve higher efficiency and precision.
