Today's modern industrial society continues to push the development and uses of new, advanced materials and high precision machining to new heights. Along with the improvements in production processes and difficulties that arise from machining new and advanced materials, there is an increasing demand for new forms of cutting tools that go beyond the performance of conventional tools made of high speed steel, tungsten carbides, cermets, and ceramics. Polycrystalline Diamond (PCD) and Polycrystalline Cubic Boron Nitride (PCBN) are a synthetic superabrasive products that are produced by sintering together selected diamond or CBN particles with a metal matrix using very sophisticated high- temperature and high- pressure technology. PCD, PCBN are by their nature high in hardness and more abrasive and shock resistant in all directions as compared to natural diamond. These wear resistant materials are combined into a cutting tool. That provides outstanding life and excellent quality of cut.
