Abstract For complex surface structure and difficult to machining materials for aeroengine blisk, the surface roughness
is outer design requirements by precision milling, and the milling texture is obvious. The experiment on the computer
numerical control (CNC) of belt grinding technology for blisk is proposed for the surface quality and profile accuracy requirements,
which is difficult to meet by the method of manual polishing. Firstly, the current belt polishing for blisk is studied,
and then, the CNC belt grinding for blisk is studied from the new belt grinding technology, force adaptive belt grinding
technology and six-axis principle. Secondly, the CNC belt grinding equipment and software are introduced. Finally, four
different blisks are used to experiment research. The results show that the surface roughness is less than 0.4μm, the profile
accuracy is less than 0.05mm and the precision consistency is significantly improved.
