Method for manufacturing a continuous drill ring for a core drill bit

摘要

Method for manufacturing a continuous drill ring (51) for a core drill bit, involving the steps of: 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; shaping the green compounds into ring segments (62, 63) under the effect of pressure; and joining the ring segments (62, 63) in a circular manner and sintering same under the effect of heat so as to obtain a continuous drill ring (51).
