Grinding experiments have been carried out on Al_2O_3, ZrO_2 and Si_3N_4 ceramics using single point diamond tools. Also, the micro plastic flow condition during the grinding test was investigated for clarification regarding various kind ceramics. Next, the relationship between depth of cut and microcracks was examined using the cylindrical grinding machine with a practical diamond wheels. The experimental results showed that micro plastic flow is dependent on a small depth of cut using a lower elastic bond wheel. The formation of the ductile mode grinding in the single point diamond grinding results and cylindrical grinding experimental results showed the possibility of applying the Hertz's formula for microcracks using the equivalent radius of the abrasive cutting edge.
