Description

Technical Field

[0001] The utility model relates to the field of aviation, in particular to an automatic polishing device for the leading and trailing edges of blades. Background Art

[0002] In the aviation industry, high-pressure rotor blades are key engine components, and their quality and performance are directly linked to the overall efficiency and safety of the engine. The leading and trailing edges of the blades require precision polishing to meet stringent surface finish and dimensional accuracy requirements. Traditional polishing methods, which mostly rely on manual labor, are not only inefficient but also difficult to ensure polishing quality. Furthermore, prolonged exposure to dust can negatively impact operator health.
