Products Description
Custom CNC Aluminum Parts, with their lightweight and high strength characteristics, are widely used in industries such as aerospace, automotive, electronics, and high-end equipment. Made of aerospace-grade aluminum alloy, the product has a grayish-white appearance and can be finished in various colors such as red, green, and black through a hard anodizing process (50μm film thickness), combining functionality and aesthetics.
Manufacturing Process
Raw Material Selection
ABased on customer product requirements, suitable aluminum alloy grades are selected from 1050A, 5052, 6061, 6063, 7075, and LY12 (2A12). Each batch of raw materials undergoes spectral analysis to ensure custom machined aluminum parts' material performance meets standards and is uniform. Impure, contaminated, or cracked raw materials are discarded, controlling product quality from the source.
CNC Milling
High-precision CNC milling equipment is used. Detailed processing procedures are developed based on custom billet aluminum parts drawings, strictly controlling key parameters: turning roundness ≤ 0.01 mm, ensuring smooth, burr-free edges; milling flatness ≤ 0.02 mm, ensuring a flat surface; grinding ensures a surface roughness of Ra 0.4 μm, improving surface texture and compatibility, enabling precise machining of complex structures and ensuring stable dimensional accuracy.
Multi-process collaborative processing
For CNC machined aluminum parts that require stamping and welding, the post-processing of stamping parts and CNC milling are seamlessly connected, with positioning accuracy strictly controlled at ±0.05mm; welding adopts deformation compensation technology, and the machining allowance is controlled at 0.1-0.3mm, taking into account connection accuracy, welding strength and processing efficiency, ensuring that the part dimensions meet the standards and the structure is robust.
Surface Treatment Processes
Hard anodizing can generate a dense, hard oxide film on the aluminum machined parts surface, with a standard film thickness of up to 50 μm. This treatment not only provides excellent wear resistance, corrosion resistance, and electrical insulation, but also achieves a variety of stable decorative colors such as black, military green, and red, meeting both functional and aesthetic requirements.
