Abstract: In order to study the effect of the intensified grinding target shooting distance on the plastic deformation of GCr15 bearing steel, simulation analysis was conducted for different target shooting distances (60 mm, 90 mm, 120 mm, and 150 mm). The target shooting distance was a single variable in the simulation process, and the simulation software used was the discrete element software EDEM. The results show that with the increase of the target distance, the plastic deformation of the bearing steel in the X-axis and Z-axis directions first gradually increases and then gradually decreases, showing an approximate parabolic variation pattern. The steel plate with a target distance of 90 mm has the largest deformation, while the steel plate with a target distance of 60 mm has the smallest deformation. According to the increase in deformation of bearing steel, it helps to form a thicker strengthening layer on the surface, and it can be inferred that the best machining effect of bearing steel is achieved when the target shooting distance is 60~120 mm.
