How high is the machining accuracy requirement of aircraft forgings?

The machining accuracy of aircraft forgings is very high, because the aircraft forgings, as an important part of the aircraft structure, need to have high strength, high stability and high reliability. The following are some common aircraft forgings processing accuracy requirements: Dimensional accuracy: Aircraft forgings dimensional accuracy requirements are very high, usually need to reach sub-millimeter or even higher accuracy. Precise dimensional control ensures that the geometry and dimensions of the forging meet the design requirements to ensure the interchangeability of parts and assembly accuracy. Surface quality: The surface quality requirements of aircraft forgings are very high, and it is usually necessary to meet the requirements of finish and flatness. This helps to improve the frictional, anti-corrosion and lubricating properties of the parts and reduces aerodynamic drag in flight. Position accuracy: The position accuracy of aircraft forgings is required to be high, including the accurate control of hole position, threaded hole, axial position, etc. This is to ensure that the parts are accurately aligned with other parts during the assembly process to ensure the stability and sealing of the overall structure. Material organization control: The material organization of aircraft forgings also needs to be strictly controlled to ensure its mechanical properties and fatigue properties. Process requirements such as heat treatment, annealing and grain control of materials need to be strictly implemented. In short, the processing accuracy of aircraft forgings is very high, and advanced processing equipment and process technology are needed to ensure that each forging meets the strict design requirements, so as to ensure the safety and reliability of the overall structure of the aircraft.
