CBN suitable for machining ferrous metals such as iron and nickel

Because of its iron, nickel, and other high-temperature alloys, which is insoluble, so the CBN for processing iron and nickel and other ferrous metals, the diamond will react with these materials and cause rapid wear of grinding wheel. Polycrystalline c-BN drilling and grinding tools used for machine steel, while diamond drilling and grinding tools and more for aluminum alloys, ceramics and glass. Such as diamonds, abrasive grinding as phonons with high thermal conductivity. Contact with oxygen at elevated temperatures, boron oxide, boron nitride will form a passivation layer. Boron nitride, and metal can be Synthetic diamond well, because the boron or nitrogen alloy interleaved layer. Cubic boron nitride crystal materials often used in cutting tools, cutting head. For abrasives, generally synthetic resin, made ​​of porous ceramics adhesives.
