Method for Manufacturing a Continuous Drill Ring for a Core Drill Bit

摘要

A method for manufacturing a continuous drill ring for a core drill bit is disclosed. The method includes forming at least two green compacts in layers in a direction of formation between a bottom side and a top side by successively applying powder layers containing a powder mixture and diamond layers containing diamond particles that are arranged in a set pattern. The green compacts are shaped into ring segments under the effect of pressure. The ring segments are joined in a circular manner and they are sintered under the effect of heat so as to obtain a continuous drill ring.
