In aerospace, safety and performance are Paramount. CNC precision machining technology is used to manufacture aircraft engine blades, the profile accuracy can reach ±0.03mm, the blade thickness error is controlled at ±0.05mm, in the high temperature, high speed environment, to ensure the stable operation of the engine, reduce the vibration amplitude up to 30%. In the manufacturing of precision components of aerospace instruments, high-precision machining can meet the harsh requirements in extreme environments to ensure the reliable operation of aircraft navigation, communication and other systems.
