Analysis of abrasive grain size effect of abrasive belt on material removal performance of GCr15 bearing steel

The effect of abrasive grain size on the material removal performances of the grinding surface was studied by theoretical modeling and grinding experiments. The results indicted that a smaller abrasive grain size of the abrasive belts led to smaller microscopic contour height and surface roughness of the ground surfaces, fewer curl chips, and more spherical chips. The smaller grain size also led to smaller macroscopic grinding depth and material removal rate. There was an approximately linear relationship between the macroscopic grinding depth and material removal rate during plane grinding. The slope was related to the abrasive grain size. Grinding force, vibration, vision, and sound signals could distinguish the macroscopic material removal changes caused by abrasive belt particle sizes.
