Cutting tool of polycrystalline diamond and method of manufacturing the same. |
摘要 |
<p>A polycrystalline diamond cutting tool is prepared by employing polycrystalline diamond, which is synthesized on a mirror-finished surface of a base material by a low-pressure vapor phase method, as a tool material. A surface, which has been in contact with the base material, of the polycrystalline diamond layer is utilized as a tool rake face. A flank of the tool is formed by laser processing. The flank is covered with a graphite coating layer in one embodiment, while such a graphite coating layer is removed by acid treatment or the like in another embodiment. In still another embodiment, a flank is formed by grinding, and a cutting edge portion is honed by laser processing. <IMAGE></p> |
