CNC machining plays a crucial role in the manufacturing of robotic parts. Five-axis linkage and high-speed milling technology enable precise machining of joint structures (±0.005mm), servo motor housings (coaxiality ≤0.01mm), and harmonic reducer components (tooth profile accuracy Ra 0.4μm). This ensures collaborative robots meet the dual requirements of lightweight construction (aluminum alloy/titanium alloy) and high strength (tensile strength ≥1200MPa).
