The JCB CBN Micro-powder refers to CBN particles with a grain size finer than 60/40 microns. It is produced using high-quality JCB CBN single crystals as raw material, through processes such as crushing, shaping, purification, and classification. JCB CBN Micro-powder is suitable for resin bond, ceramic bond, and metal bond applications. It is widely used for grinding and polishing ferrous metals, as well as for producing high-quality PCBN (polycrystalline Cubic Boron Nitride) polycrystalline sheets and PCBN composite sheets.
