Research on Forming and Polishing Technology Based on Belt Flap Wheel

Abstract

Belt flap wheel is a kind of special-shaped coated abrasives with the advantages of good polishing quality, long life, high efficiency, low cost and so on. It is suitable for polishing various curved surface parts such as shaft, large aperture and large plane. Combined with these polishing characteristics of belt flap wheel, this paper provides a new polishing method of smooth spiral surface forming polishing method based on belt flap wheel with high precision, high efficiency and low cost. This paper analysed the polishing mechanism of spiral curved surface, establishing a mathematical model of screw helical surface. The space contact between the flap wheel and the helical surface was determined. The profile of the flap wheel was designed. The dressing technology of the profile of the belt flap wheel was studied, and a simple dressing test device was set up to complete the finishing test of the flap wheel. The results show that it is feasible to use the belt flap wheel to polish the screw surface.
