Robotics & Automation Aluminum

E Expert Experience

For a 6-axis industrial robot arm manufacturer in Japan, we machined the base mounting plate to a flatness of 0.02mm and a surface finish of Ra 0.8μm—critical for maintaining the robot's positional accuracy over millions of cycles. A single micron of flatness error translates to 0.5mm positional error at the robot's end effector. We also developed a lightweight honeycomb arm cover for a collaborative robot (cobot) application that reduced weight by 40% compared to the previous steel design while maintaining ISO 10218-2 safety margins for human-robot collaboration. Our ISO 9001:2015 certified process includes 100% CMM inspection on critical dimensions before shipment.
