PCD PCBN 84 / NORTON WINTER PRECISION TECHNOLOGY TOOL GRINDING Diamond is the hardest known material and is used as MCD (monocrystalline diamond) and PCD (polycrystalline diamond) in the tools industry in a multitude of ways. The machining of diamond is not only difficult due to its hardness. Diamond is very brittle and therefore needs very free-cutting grinding wheels to generate good cutting edge qualities. The second hardest known cutting material is polycrystalline boron nitride (PcBN). When turning and milling hardened steels, cast iron and sintered metals, PcBN grinding tools provide enormous tool life advantages over conventional carbide tools.
