In this paper, new polishing machine was developed to make the more excellent surface after ultra-precision grinding of aspherical glass lens mold. Our design concept adopts two strategy of eccentric motion mechanism and airbag polishing tool. All machine movements including eccentric polishing motion were controlled by PC-NC motion controller. Airbag tool was modified using spindle and can be inflated by air pressure to fit with aspherical surface. Further verification study can be expected to get the more uniform and better surface roughness by polishing machine.
