Impeller
Blades, impellers and turbine discs are the key parts of aero engines, which account for about one-third of the manufacturing volume of the whole machine, and are the largest number of parts in the engine. The impeller is a typical overall complex structural parts, the parts are large in size, thin in wall, high in dimensional accuracy and surface quality, the selection of difficult-to-machine materials, poor overall manufacturability, difficult processing, the machining process should be mat...
