摘要：
Surface quality and profile precision of the blisk have a great influence on the air flow dynamics and performance of the aeroengine, and the polishing technology is the key to guarantee the final surface quality and profile precision. The polishing technology and equipment for the blisk abroad are strictly kept secret, while, the method of manual polishing is still widely used in domestic aviation enterprises; therefore, it is of necessity to make a summary of the current situation and development trend of polishing technology for blisk to provide a reference for the development of blisk polishing technology and its automation. Firstly, the necessity and importance of the blisk polishing process are summarized and the polishing process of the blisk is analyzed separately with the aspects of the structure characteristics, material properties and surface characteristics, and at the same time, the requirements of the blisk polishing process are introduced. Secondly, the current situation of polishing technology for blisk at home and abroad is summarized from the aspects of electrochemical machining, abrasive flow machining, belt grinding and so on. And then, the research content of and solution to the key problems for the blisk polishing technology are proposed based on the analysis. Finally, the development trend of polishing technology for blisk is generalized according to the technical status and key problems of the blisk. © 2016, Press of Chinese Journal of Aeronautics.
