Precision Aluminum CNC Milling Components for Industrial Applications

High-Precision Custom Aluminum CNC Machined Components

The material selected is AL6061-T6 aluminum alloy, renowned for its exceptional combination of high strength, excellent machinability, and superior corrosion resistance. This makes it the preferred choice for premium automotive components, especially in high-performance applications.

The raw material dimensions measure 125mm × 85mm × 30mm, providing ample machining allowance to ensure precision and dimensional accuracy throughout the manufacturing process.

Designed as the standard charger housing for Porsche’s latest vehicle models, this component serves as a critical structural and aesthetic element. It must not only fulfill rigorous functional requirements—such as mechanical protection, installation compatibility, and electrical insulation—but also meet exacting visual standards that align with the luxury brand identity of premium vehicles.

Our machining process leverages advanced High Precision CNC Milling technology, utilizing Brother high-speed CNC machining centers to guarantee consistent quality and tight tolerances. During rough machining, spindle speed is set at 12,000 rpm with a feed rate of F0.2 for efficient material removal. In the finishing stage, spindle speed increases to 15,000 rpm while the feed rate is reduced to F0.06, enabling micron-level control for flawless contour definition.

Given that the final surface undergoes 150# sandblasting followed by anodizing, and conventional CNC milling marks cannot be fully concealed by these treatments, a specialized polishing step is integrated into the workflow. After CNC milling, the housing surfaces are subjected to fine polishing to completely eliminate machining artifacts, ensuring optimal flatness, smoothness, and surface integrity.

For logo details during the prototype phase, EDM (Electrical Discharge Machining) cutting is employed to achieve unparalleled precision in intricate features. In mass production, the process can seamlessly transition to mold stamping, offering a balance between efficiency, consistency, and scalability—highlighting the adaptability and flexibility of our Precision CNC Milling Service.

Surface treatment options are highly customizable. The primary solution is glass bead blasting followed by anodizing, delivering a uniform texture with outstanding wear resistance, scratch resistance, and stain resistance. Available standard colors include bright silver, glossy black, red, blue, and purple. Custom color matching is also available to meet specific client requirements, ensuring perfect alignment with diverse vehicle design languages and individualized branding needs.
