CNC Machining of Extruded Aluminum: Precision Milling, Turning, and Broaching

CNC machining of extruded aluminum parts is an integrated manufacturing solution for industries requiring a combination of complex profiles and absolute mechanical precision. At modern facilities in Bac Ninh, Vietnam, the production process is optimized from 6000 Series aluminum extrusion to refined stages using multi-axis CNC milling-turning machines and specialized broaching techniques. This synergy allows for the fabrication of spare parts with hollow structures, internal keyways, or splines with perfect repeatability. VINACNC is proud to offer an enclosed production workflow that meets rigorous standards for tolerances and aesthetics for the global export market.

Multi-Technology Aluminum Machining Expertise at VINACNC

The coordination between forming and subtractive machining methods provides superior technical advantages for components:

Aluminum Profile Extrusion: Creates long aluminum blanks with material consistency, significantly reducing residual waste and machining time.
Multi-axis CNC Turning and Milling: Finishing 3D profiles, flanges, and assembly holes with micron tolerances. Controlling ultra-fine surface roughness at thermal or motion contact points enhances component operational performance.
Precision Broaching Techniques (Broaching Type): This is a specialized technology for machining internal keyways, square holes, or splines within aluminum parts that conventional milling bits cannot easily reach. Broaching ensures absolute flatness and dimensional precision throughout the entire length of the groove.

Professional Export Packaging and Preservation Process

Machined aluminum components require strict protection to maintain surface finish and mechanical precision. VINACNC implements a rigorous international standard packaging process for shipping from Vietnam:

Ultrasonic Cleaning: Thoroughly removes aluminum dust, cutting oils, and impurities from crevices or threaded holes using industrial ultrasonic systems.
Surface Anti-Oxidation: Utilizing specialized VCI anti-rust paper or PE protective film to prevent salt-air humidity impacts during long-duration transit.
Multi-layer Cushioning: Each component is wrapped in thick bubble wrap and placed in shaped foam trays or separated compartments to eliminate mechanical vibration and impact.
International Standard Crating: Products are packed in fumigated wooden crates (ISPM 15 standard) or high-grammage reinforced cartons with secure strapping.
Traceability Labeling: Clear labeling displaying part codes, specifications, and barcodes for efficient destination logistics control.
