Products Description
CNC precision machining parts are core metal cutting solutions for lightweight structures, thermal management needs, electromagnetic shielding, and industrial aesthetic expression. As the second largest metal engineering material after steel, aluminum alloys are transformed from raw blanks into functional components with complex geometries through CNC milling, turning, and composite machining technologies. Their unique anodizing surface transformation capability further endows products with a leap from functional gray-white metallic texture to colorful industrial aesthetics.
Design and Manufacturing Advantages
High Structural Adaptability
Capable of aluminum machined parts with complex internal structures and irregular shapes, especially machined parts (such as shafts and sleeves) with extremely high precision requirements.
Lightweight and High-Strength
The aluminium machining parts material itself possesses high-strength properties, enabling it to withstand significant mechanical loads while remaining lightweight.
Long-Term Durability
The hard anodized film has an extremely long lifespan, ensuring stable performance for custom machined aluminum parts even in harsh environments.
Production Process
CNC Precision Machining
The pre-treated aluminium CNC parts substrate is sent to the CNC machining workshop. Based on the design drawings, suitable equipment and tools are selected. Milling, drilling, and other processes are completed through closed-loop control and multi-axis linkage technology. The entire process is automated, with real-time monitoring of machining parameters and temperature.
Surface Polishing
After CNC machining, the custom machined aluminum parts is finely polished to remove minor burrs and scratches, ensuring a smooth surface (roughness Ra≤0.4μm) and flatness. This provides a uniform substrate for hard anodizing, avoiding uneven oxide film and color difference issues.
Hard Anodizing and Multi-Color Coloring
The polished aluminium machining parts is sent to the anodizing workshop. Strict process parameters ensure an oxide film thickness of 50μm. Subsequently, multi-color colors are customized using environmentally friendly colorants according to requirements. Color uniformity is strictly controlled. After coloring, a sealing treatment is performed to improve adhesion and color durability.
Customer reviews
Based on customer feedback, our aluminum machined parts demonstrate consistent dimensional consistency and surface quality, high assembly fit, and significantly reduced on-site rework rates. They have received particular praise for their excellent wear resistance and color difference control after hard anodizing. Long-term clients generally commend our timely delivery response and professional technical communication, which helps shorten the overall project development cycle.
