摘要:
Polycrystalline diamond cutters have a substrate (110), a diamond body (120) including a planar oriented portion (240) and a projecting portion (250), and a passage (130) extending through the cutter along an axis (140) from an opening in a lower side of the substrate to an opening in a first side of a diamond body. The planar oriented portion of the diamond body is attached to the upper side of the substrate and the projecting portion of the diamond body forms at least a portion of an inner wall surface of the first passage. When mounted on drilling tools, heat generated in the cutters by drilling action is transported away from heat generating regions through the diamond body's contact with fluid medium in the passage as well as through the diamond body itself with the body of the drilling tool functioning as a heat sink. Methods of production of the cutter are also disclosed.
摘要(中):
多晶金刚石刀具具有衬底(110),包括平面定向部分(240)和突出部分(250)的金刚石本体(120),以及延伸穿过刀具(130)的通道(130) 沿着从衬底的下侧的开口到金刚石本体的第一侧中的开口的轴线(140)。 金刚石体的平面取向部分连接到基底的上侧,金刚石体的突出部分形成第一通道的内壁表面的至少一部分。 当安装在钻孔工具上时,通过钻孔作用在切刀中产生的热量通过金刚石体与通道中的流体介质接触并通过金刚石体本身从钻孔工具的主体作为 散热器。 该刀具的生产方法也被公开。 p>
