Aiming at the polishing of compressor blade mounting plate, this paper carries out the applied research based on the automatic polishing technology proposed by Beihang University. Combined with the complex surface or structural features of blade mounting plate area, the polishing accuracy and surface roughness can meet the design requirements by the optimization of polishing wheel granularity, polishing process and contact pressure. The test results show that the purpose of replacing manual polishing has been realized, with the surface roughness Ra being less than 0.4μm and material removal amount less than 0.03mm. The polishing efficiency has also been matched with the production cycle of several NC milling machines. The process system is stable during the trial production (200 blades). It is proposed that the polishing technology will be widely used in the development and production of compressor blades.
