Investigating adhesion wear on belt and its effects on dry belt finishing

Abstract

Adhesion wear on abrasive belt sometimes occurs as an abnormal abrasion way because of an improper selecting on working conditions during the belt finishing. In this paper, the forming process of the adhesion wear and its effects on the finished surface is investigated through a series of experiments. The results reveal that the applied pressure and the belt feed rate are supposed to be the two sensitive variables for forming the adhesion wear. A certain amount of accumulated chips is a trigger to cause adhesion wear initially, and then, the sufficient heat accumulation becomes the main factor for the following adhesion wear. Thus, shortening the finishing duration, decreasing applied pressure, rotating speed and introducing cooling/lubrication system are recommended to avoid adhesion wear. The belt finishing process with adhesion presents a potential to further decrease surface roughness by 30% maximum, improve bearing characteristics and obtain equivalently high compressive residual stresses; however, this merit has to go with the sacrifice of belt’s cutting ability.
