    As the hardness of SiC is very close to that of diamond, the diamond grinding wheel will be severely worn, primarily when ultra-fine grains are used. Pan et al. reported that the wheel wore out 1 μm every 6.78 μm grinding in 2-inch SiC wafer grinding with cup diamond grinding wheels. The wear of the grinding wheel leads to severe material
