Abstract

Diamond based grinding or cutting tools usually consist of randomly packed diamond particles inside a metal matrix. Nevertheless, it is known that an ordered arrangement of diamonds shows much better performance with defined wear of the tool, which typically leads to a longer service lifetime. Several approaches and patents were already published on this topic, but due to the high complexity of the manufacturing process the market penetration is still low. Fraunhofer IFAM and DiaBü have developed a modified 3D screen printing process which allows the manufacturing of cutting beads with ordered diamond structure in a mass production process. With 3D screen printing, a user defined 3D arrangement of cavities can be built, into which the diamonds are incorporated. After closing of the cavities, the beads are debound and sintered. In the present work also results of cutting tests of beads with an ordered diamond structure will be presented.
