PURPOSE:To make machining easier, give a longer tool life, and reduce the time required for regrinding by utilizing the anisotropy of diamond when forming a single crystal diamond tool. CONSTITUTION:A single crystal diamond is held on a tool shank in such a way that a crystal face, which is inclined in the direction of a face (110) from a face (100) at an angle alpha deg. of 12 deg., is used as the face, a face (010) side is used for the front flank, and the face (110) side becomes the bottom of the shank. Thus, when the machining is made, in forming the face, from the shank side toward the fron flank side, the machining efficiency is improved about 1.5 times more than in the case of using the conventional longitudinal edge tool which has provided easy machining of faces, while a slick surface is also provided. |
