The surface integrity of the blisk has a great influence on the engine performance and service life

and the polishing technology is the key technology to realize the blisk performance manufacturing. In view of the problem that the blisk does not meet the use requirements after forming and manufacturing

the characteristics of polishing were analyzed from three aspects of material characteristics

structural characteristics and processing requirements. The development history

research status and polishing effect of polishing technology were introduced from the aspects of manual polishing

numerical control polishing

abrasive flow polishing

magnetic abrasive finishing and barrel finishing. And the advantages and limitations of each polishing technology were compared and analyzed. On this basis

the development trend of the blisk polishing technology was put forward

to explore the precision and performance coordination type and multi-process combination type of polishing technology

to realize the intelligent decision making of the polishing process

and to the direction of green environmental protection.
