CNC in the field of aviation, the precision of aircraft parts is extremely high. For example, the precision of aircraft flaps directly affects the flight performance and safety of the aircraft. Aluminum alloy non-standard parts are widely used in aircraft manufacturing, the machining accuracy requirements are usually within a few hundredths of a millimeter or even smaller dimensional deviation, CNC machining technology can meet this high demand for accuracy through precise programming and control. Such as in the processing of aircraft engine turbine blades, intake guide blades and turbine disk and other components, CNC machining can produce complex shapes of parts, and to ensure its dimensional accuracy and surface quality. At the same time, for aircraft fuselage connectors, support structures and fuel tanks and other aerospace structural parts, CNC machining can also ensure their accuracy, improve the strength and rigidity of the structure, so that the aircraft has better flight performance and fuel efficiency.
