| Abstract: |
| The work aims to improve the surface quality of ZrO2 ceramics by magnetic abrasive finishing, explore the influence of the main process parameters on the surface quality of ZrO2 ceramics, and finally obtain the optimum combination of the process parameters of the magnetic abrasive finishing ceramic material. Magnetic pole manufactured with Mi shape was used. Magnetic abrasive finishing of ZrO2 ceramic material wascarried out by using spherical magnetic abrasives. With the help of XK7136C CNC milling machine, its surface modification ability was explored. With the aid of white light interferometer and scanning electron microscope, the surface morphology of the polished surface was analyzed. The effect of spindle speed, machining gap, filling amount and feed speed on the surface roughness was investigated by single factor experiment method, and a reasonable interact orthogonal experiment was designed to find the best combination of process parameters. In the process of ZrO2 ceramic material processing by magnetic abrasive finishing, when the speed S=1000 r/min, the machining gap=2.5 mm, the filler content m=2.5 g and the feed speed v=15 mm/min, the average surface roughness of the work-piece could be reduced from 1.950 μm before the grinding to 0.493 μm, and the surface roughness decreased obviously. By test of white light interferometer and scanning electron microscope, we could see that the surface burr of the work-piece had been greatly reduced and the surface quality had been improved. The magnetic abrasive finishing technology and the best parameter combination can effectively reduce the surface roughness of ZrO2 ceramic material and obtain high quality surface. |
