CNC Aluminum Milling

CNC aluminum milling is one of our most mature precision machining services. Aluminum alloy offers light weight, excellent machinability, and good strength after heat treatment. It is the most widely used structural material in aerospace, automotive, electronics, medical devices, and automation equipment. Our CNC aluminum milling service covers the entire process from prototyping to mass production. We machine all common aluminum grades including 6061, 6082, 7075, 5083, and 2024. Our CNC aluminum milling delivers consistent quality across every batch.

Our CNC milling workshop has over 60 machines including 3-axis, 4-axis, and 5-axis machining centers. 5-axis simultaneous machining completes complex curved surfaces, angled holes, and special structures in a single setup. This avoids cumulative errors from multiple setups. Our CNC aluminum milling capability covers parts from a few millimeters to large aluminum frames over 1 meter. We consistently achieve dimensional tolerances of ±0.01mm. Coaxiality and position accuracy are within 0.02mm. Surface roughness is controlled at Ra≤0.8μm for standard milling and Ra≤0.2μm for mirror finish milling.

Quality control for CNC aluminum milling is as strict as all our products. First-piece inspection uses a HEXAGON CMM for full dimension check. Mass production only starts after the first piece passes. During production, operators self-inspect every 15 minutes. Quality inspectors do patrol checks every 2 hours. We focus on tool wear that causes dimensional deviation. Our red ruby probe online measurement system provides real-time compensation for critical dimensions. This ensures batch-to-batch consistency. Our CNC aluminum milling batch defect rate is below 200ppm. We accept orders starting from 1 piece. Prototyping takes 3-7 days depending on complexity. Batch production takes 15-30 days. Standard warranty is 1 year. If your project requires high-precision, high-consistency CNC aluminum milling, send us your drawing. Our process engineers will provide DFM evaluation and quotation within 24 hours. We also offer surface treatment services including anodizing, sandblasting, and powder coating. This provides one-stop delivery from blank to finished part.
