This study is focused on research in the field of grinding cermet materials. Different grinding conditions in terms of several cutting speeds were used for grinding two cermets with different chemical compositions. A diamond grinding wheel and the same grinding strategy was used for each test. The influence of the cutting speed on the spindle load and the calculated cutting force was observed. It was found that higher cutting speed causes lower calculated cutting force but higher spindle load because of the higher RPM of the grinding wheel. This affects the grinding process and the resulting quality of the ground surface. Cracks and breakout occurred on the surface when the higher grinding wheel speed was used. The grinding wheel was dressed before each test to ensure the same grinding ability. The profile of the grinding wheel was scanned during grinding using an optical device to see the effect of the cutting speed and dressing on the wheel wear. The results of this work will be used for a better understanding of the process of grinding cermet.
