Abstract: Grinding plays the critical role in manufacturing the aero-engine components composed of nickel-based superalloys. In order to further improve the material removal rate and workpiece quality, a large number of researches on grinding technology of nickel-based superalloys are conducted in terms of the fundamental theory and process expending. In this review article, the basic principle and development process of grinding are firstly introduced briefly. Then, the technologies are reviewed detailed concerning the material removal mechanism, the grinding characteristics, and the novel application type of grinding for nickel-based superalloys. Finally, the development trends during grinding of nickel-based superalloys are proposed as well as the difficulties in grinding of such materials.

Key words: grinding, grinding wheel, material removal mechanism, nickel-based superalloy
