The choice of particle size mainly depends on the requirements for the machining accuracy and production efficiency of the workpiece surface. Coarse-grained and medium-grained abrasives are suitable for rough machining and semi-finishing, while fine-grained abrasives are used for finishing and super-finishing. The physical and mechanical properties of the workpiece being ground are also factors that determine the particle size. Coarse-grained abrasives are suitable for materials with low hardness, high ductility and toughness, while fine-grained abrasives are suitable for materials with high hardness and brittleness.
