This paper deals with the lapping characteristics for crystallographic orientation of single crystal diamond. The rough diamonds were lapped by cast iron lap as well as steel lap and diamond wheels. The lapping removal depth, lapping force ratio (tangential force / normal force) and lapping temperature for lapping direction on the typical three planes were measured. Experimental results are as follows : the relationship between lapping removal depth and lapping force ratio was devided into the following two trend. In the lapping by cast iron lap and steel lap, at the easy lapping direction (i. e. {110}, <100>) lapping force ratio was small and lapping temperature was low, at the hard lapping direction ({110}, <110>) the former value was large and the latter was high respectively. On the other hand, in the lapping by diamond wheel, at the easy and hard lapping direction these two values changed conversely in the tendency of the cases by cast iron and steel lap.
