In the experiment, the surface of SUS304 stainless steel was ground and polished with the parameter setting of polishing liquids of different concentrations, different magnetic pole rotation speeds, different vibration platform rotation speeds, different grit weights and numbers, and different silicon carbide and boron carbide particle sizes to discuss the surface roughness and observe the surface morphology of the test piece after grinding and polishing. 　　According to the experimental results, with 1 g of boron carbide powder having a particle diameter of 0.7 µm, 4 g of grit with a grit number of #120, 3 g of grinding liquid, a magnetic pole rotation speed of 550 rpm and a platform rotation speed of 1500 rpm, the roughness of the SUS304 stainles steel can be lowered from 0.19μm to 0.024μm in 15 minutes, and the improvement rate is 87.37%. Could effectively remove markings in the surface of SUS304 stainless steel, and the surface cracks and knife marks of the test piece were significantly reduced. The experimental results show that the best parameters have a better improvement effect on the surface.
