Aspects in the grinding of ceramics have been investigated. Si[sub 3]N[sub 4], ZrO[sub 2], SiC, and Al[sub 2]O[sub 3] were ground with resin-bonded diamond wheels of grit numbers ranging from 80 to 800. Microstructural observations of ground surfaces show that grinding occurs predominantly by flow mode in Si[sub 3]N[sub 4] and ZrO[sub 2], and by fracture and grain pullout in SiC and Al[sub 2]O[sub 3]. The measurement of grinding force shows that grinding resistances in Si[sub 3]N[sub 4] and ZrO[sub 2] are significantly larger than those in SiC and Al[sub 2]O[sub 3]. As the grit number of the grinding wheel increases, maximum surface roughness significantly decreases in Si[sub 3]N[sub 4], ZrO[sub 2], and SiC, but it apparently does not change in Al[sub 2]O[sub 3]. This unexpected result in Al[sub 2]O[sub 3] is discussed in terms of the observed grinding mode and microstructure.
