Abstract: When grinding titanium alloys with green silicon carbide wheel, the wheel achesion is serious and the grinding ratio is very low. In order to improve the grindability of titantium alloys, the main reasons causing severe wear of grinding wheel are analysed. The wear of grinding wheel caused by the adhension diffusion and fracture is discussed, and the influence of grinding conditions on the wheel wear is studied. Based on the experimental studies and theoretical analyses, the main ways to rais egrinding ratio and to decrease the wear of grinding wheel are proposed.

Key words: titanium alloys, grinding, grinding wheel wear
