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%.
