Abstract In order to solve the problem of finishing ultra-rough ZrO2 ceramics, the magnetic shear thickening and finishing medium was prepared. The influence of processing with different abrasive types and particle sizes was investigated using the designed magnetic field generator under the experimental parameters of spindle speed of 900 r/min, X axis feed speed of 10 000 mm/min and processing clearance of 0.7 mm. The surface roughness of the workpiece was increased by 38% within 180 min with 250 μm green silicon carbide magnetic shear thickening finishing medium. The roughness of the workpiece surface was increased by 41% in 210 min with 10 μm cubic boron nitride as magnetic shear thickening finishing medium. The processing efficiency increased with the increase of abrasive hardness under the condition of same abrasive particle size. Moreover, under the condition of the same abrasive mass fraction, the smaller abrasive particle size was, the smaller surface roughness value was obtained. The results showed that the processed surface became smooth and the material was removed, which verified the effectiveness of the proposed method compared with the orignal surface.
