Turbine blades are the key components of aero-engines, and their size accuracy and surface quality directly affect the performance of the engine. Turbine blades are usually made of refractory materials such as high-temperature alloys, the surface of which is free surface of space, the processing technology is complex, and polishing is the final process of blade processing, and the polishing process directly affects the surface quality and processing efficiency. The whole turbocharged turbine is polished using a one-design fixture polishing process, which can squeeze the abrasive into the turbine cavity, polishing evenly without dead corners, effectively improving the turbine's air pressure efficiency.
