Abstract

Abstract: To solve the problems of shortlife of abrasive belt in aero-engine titanium alloy blade grinding, experimental research on abrasive belt grinding processes of titanium alloy samples was carried out on a new type of alumina hollow-sphere abrasive belt. The effects of processing parameters on the surface roughness and grinding ratio of titanium alloy sample processed by alumina hollow-sphere abrasive belt were analyzed through single-factor experiments, and the reasonable grinding parameter ranges of titanium alloy with hollow-sphere abrasive belt were determined. Then the influence degrees of grinding force, grinding speed, feed speedand grain size on surface roughness and grinding ratio were studied through orthogonal experiments to determine the optimal combination of processing parameters for titanium alloy grinding with hollow-sphere abrasive belt.

Key words: abrasive belt, hollow-sphere, titanium alloy, grinding ratio, surface roughness
