    The grit size is mesh no. 320 for the coarse grinding wheel and mesh no. 2000 for the fine-grinding wheel. The radius of the wheels is 140 mm. Single crystal silicon wafers of 200 mm in diameter with (1 0 0) plane as the major surface (the front or back surface of the wafer) are used for this investigation.
