The lapping characteristics of single crystal diamond are studied by considering the crystallographic anisotropy. It is introduced for lapping method to identify crystallographic orientantion by the X-ray diffraction and to measure lapping force ratio, lapping temperature and lapping wear. Diamound bonded wheels are used for lapping under dry condition. On the lapping {110} and {100} planes, it shows remarkable crystallographic anistropy. The lapping force ratio, temperature and wear become gerater with sliding direction along the <100> than along <110>. The results also show that the wear of diamond is influenced by mechanical work(tangential lapping force * lapping distance) as well by lapping speed.
