    • PROBLEM TO BE SOLVED: To provide a PCD cutting insert for a machine tool which is improved to be manufactured more economically.SOLUTION: In the cutting insert (20) for a machine tool which constitutes a flat-blade formed of polycrystalline diamond materials, and of which the surface has a front face (21) formed of a PCD phase (23), and a rear face formed of a second phase substrate (24). The insert is provided, on its rear face, with a serration (25) formed in the second phase substrate (24), more preferably, substantially perpendicular to each cutting end. The cutting insert (20) is rectangular in a plane view, and is held by a recess formed at a tip of a cutting tool, and the serration at the rear is engaged with a plurality of serrations of the recess. The cutting insert (20) is configured to rotate at 90° from a first holding position in the recess so as to be held by the recess, and in this case, the serration on the rear face is also engaged with the serrations of the cutting tool.
    • 要解决的问题:提供一种改进以更经济地制造的用于机床的PCD切削刀片。 解决方案:在用于构成由多晶金刚石材料形成的平面刀片并且其表面具有由PCD相(23)形成的前表面(21)的机床的切削刀片(20)中,以及 由第二相衬底(24)形成的后表面。 插入件在其后表面上设置有形成在第二相衬底(24)中的锯齿(25),更优选地,基本垂直于每个切割端。 切削刀片(20)在平面图中为矩形,并且由形成在切割工具的尖端处的凹部保持,并且后部的锯齿形与凹部的多个锯齿接合。 切削刀片(20)构造成从凹部中的第一保持位置以90°旋转,以便被凹部保持,并且在这种情况下,后表面上的锯齿也与切割锯齿接合 工具。 版权所有(C)2013,JPO&INPIT
