<p>IMPROVED PROCESS FOR MAKING DIAMOND AND CUBIC BORON NITRIDE COMPACTS The high pressure/high temperature (HP/HT) process for making diamond or CBN compacts has been modified by placing partitions within the crystal mass before HP/HT processing. Pliable metal shapes are placed in a honeycomb pattern within a shield metal sleeve and a shield metal cup. The abrasive crystals within one set of the tubes and outside another set of the tubes is sintered, and a compact containing the tubes embedded therein results. This compact can be acid leached to give a plurality of small compacts which need little if any additional shaping. The partitions can also be left intact as chip arresters.</p> |
