Abstract：Abrasive belt abrasive wear will affect the surface quality of the grinding, and then affect the service
performance of the grinding components. This paper uses the surface integrity as the evaluation index to evaluate the grinding quality of the abrasive belt before and after abrasive wear, and analyzes the effect of abrasive wear on the surface roughness, residual stress and surface micro-hardness of the abrasive belt grinding TC17. Results show that: after the abrasive grains are worn, due to the uniformity of the abrasive grains, more abrasive grains per unit area actually involved in cutting, grinding depth reduced. The grinding texture is uniform and fine, and the roughness decreases up to 70.3%. Compared with worn abrasive grains, the machined surface of sharp abrasive belts has undergone significant plastic deformation, and the hardness of abrasive abrasive belt surface can be increased to more than 20% by work hardening. On the other hand, the material plastic flow occurs on the surface processed by wore abrasive belt, so the surface micro-hardness is slightly lower than the matrix hardness. In this experiment, grinding surface has realized the transformation of residual tensile stress (about 400MPa) to residual compressive stress (about –300MPa). The abrasive wear of different abrasive belts has different effects on surface residual stress. Abrasive wear of zirconium corundum abrasive belt increases surface residual compressive stress by 33%, and abrasive wear of diamond abrasive belt reduces surface residual compressive stress by 34%.
