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.
