    • A mandrel for use in an arc-jet spinning diamond deposition process for coating cutting tool inserts is disclosed. The mandrel has a plurality of cutouts or wells for receiving cutting tool inserts. The receiving wells are machined or otherwise provided to have the same contour as the cutting tool inserts that are placed in the wells. The receiving wells may all have an identical geometry, or different geometries. In one embodiment, the mandrel comprises a single element with the receiving wells machined into the upper surface of the mandrel. In another embodiment, the mandrel comprises a separate upper plate with the receiving wells cut through the plate to form a grid, and a lower base plate which is attached to the upper plate. An intermediate layer of a low melting metal foil may be placed between the grid and base plate to aid adhesion and to provide an interface of high thermal conductivity.
    • 公开了一种用于电弧喷射纺丝金刚石沉积工艺中用于涂覆刀具刀片的心轴。 心轴具有用于接收切削刀具插入件的多个切口或孔。 接收井被加工或以其他方式提供以具有与放置在井中的切削工具插入件相同的轮廓。 接收井都可以具有相同的几何形状或不同的几何形状。 在一个实施例中,心轴包括单个元件,其中接收孔被加工成心轴的上表面。 在另一个实施例中,心轴包括单独的上板,其中接收井切穿板以形成格栅,以及附接到上板的下基板。 低熔点金属箔的中间层可以放置在栅格和基板之间以辅助粘附并提供高导热性的界面。
