Precision CNC Machining Service for Aluminum Parts

Product Summary: Unionfab delivers high-precision CNC machining services for aluminum components using 3-, 4-, and 5-axis machining centers. With tolerances down to ±0.0002" (±0.005mm) and surface finishes up to Ra 0.4µm, our aluminum parts are trusted by automotive, robotics, and industrial equipment manufacturers. Supported by ISO 9001:2015 certified processes and a 100+ engineer R&D team, we ensure fast turnaround and consistent quality.

Key Selling Points

• Tolerance ±0.0002": Achieve tight dimensional accuracy for critical aluminum components, ensuring interchangeability and assembly fit.
• Materials: Aluminum 6061-T6 & 7075: High strength-to-weight ratio with excellent machinability, ideal for structural and dynamic parts.
• Multi-Axis Machining (3/4/5-Axis): Complex geometries, undercuts, and thin-wall features milled in a single setup.
• No MOQ, 1-5 Day Lead Time: Low-volume prototypes to high-volume production with rapid turnaround.
• 100% CMM Inspection: Full dimensional verification with inspection reports provided per batch.
