Polycrystalline Cubic Boron Nitride (PCBN) is created through the sintering of cBN powders with a mix of ceramic and metallic binders. CBN, ranking as the second hardest material after diamond, boasts remarkable thermal and chemical resistance. PCBN tools, designed for machining hardened steels, irons, and powder metals, find widespread application across industries. EHWA's PCBN tools stand out as the preferred solution in sectors like automobiles, general machinery, and bearings where the machining of hardened steel is prevalent.
