ダイヤモンド工具の研磨に関する研究 Ｉ 鋳鉄円板による基礎的研磨実験

Abstract

In order to obtain the single crystal diamond tools which have clear crystallographical orientation of the tool faces, the lapping method with identifying technique by the X-ray diffraction is studied. The lapping temperature is measured as well as the lapping forces and the total lapping depth to consider a lapping mechanism of the diamond tool. The addition of oscillation to the lapping operation lowers all the tangential lapping force, the lapping temperature and the total lapping depth, which have more effect on so called card to lap direction on {110} plane than on easy to lap direction on {110} plane. It is also found that the lapping temperature increases with the normal force to the lap, but the lapping force ratio (tangential force/normal force) decreases, and that the lapping surface roughness of diamond by the oscillatory lapping is superior to one by the non-oscillatory lapping.
