Product Overview

Robot joints serve as the core motion units of robotic arms. This aluminum CNC joint housing is integrally machined from 6061 / 7075 aluminum alloy on 5-axis CNC equipment. It features lightweight design and high rigidity, with anodized finish for anti-corrosion and wear resistance, ideal for collaborative robots and small industrial robotic arms. Customization from drawings or samples available, supporting rapid prototyping & mass production.

 Key Advantages

1. Precision: Tolerance up to ±0.005mm. Curved surfaces and mounting holes formed in one operation for smooth joint rotation without jamming.

2. Material: Optional 6061 / 7075 aluminum, light weight and good thermal conductivity to reduce self-load of robots.

3. Processing workflow: 5-axis CNC milling → deburring → sandblasting → hard anodizing to enhance surface hardness.

4. Lead time: 3–7 days for prototype sampling, small & medium batch production supported.

Applications

Collaborative robots, 6-axis industrial robotic arms, educational robots, light-duty robotic arm joint modules
