摘要

Based on an analyses of the factors affecting the performance and life of a blisk, and in light of the theory of its structure and material features as well as the characteristics of its manual polishing process, this paper proposes an adaptive polishing implementation method. The flexible grinding head for the blisk, the working principle and the adaptive region of the flexible grinding head are studied, and the control technology is discussed. The feasibility of the flexible polishing method is verified so as to achieve the automatic mechanical polishing of a blisk. Preliminary polishing test results show that the automatic process raises polishing efficiency by more than 50 percent as compared with the manual polishing process, and the production cycle of a blisk is shortened obviously, while the surface roughness of the blisk is as low as Ra 0.4. The polishing method also satisfies the demands of consistency, stability and surface quality, reduces labor intensity and production cost.
