Application & Detailed Description:

High-precision knuckle components specially designed and manufactured for finger joints of humanoid robots. Made of 7075 aerospace aluminum alloy and precision-machined by 5-axis simultaneous CNC. Equipped with a hollow lightweight internal structure, the parts greatly reduce joint load while maintaining sufficient strength. With black anodized surface treatment, they feature excellent wear resistance and anti-corrosion performance. They are suitable for dexterous hands of humanoid robots and end effectors of collaborative robots.
