On the honing of fine ceramics, the influence of concentration and grain size of the diamond stick on honing performance is investigated theoretically and experimentally. The workpieces are alumina Al2O3, silicon nitride Si3N4 and silicon carbide SiC, which are sintered under atmospheric pressure. The results are as follows. The effects of concentration and grain size on the cutting ability can be expressed by a simple equation. This equation can explain the tendency of experimental results. The diamond stick of lower concentration of grain is superior in the cutting ability, but it cannot have the higher finishing ratio. On the other hand, since the stick of higher concentration has many grits on its working surface, it is superior in finishing ratio but inferior in the cutting ability. Therefore, SiC and Si3N4 which have poor machinability should be honed with the stick of low concentration, but then the high finishing ratio cannot be obtained. For Al2O3 having good machinability, the stick of high concentration should be used to obtain the high finishing ratio. The stick with fine diamond grains improves the surface roughness, for example, #1 200 stick can make the surface of Si3N4 to the mirror finish, but it is not economical for material removing.
