As we all know, the three factors that determine the performance of cutting tools are the base material, tool coating and geometric geometry. Because of this, although China is a resource country of cemented carbide minerals, in terms of finished tool products, due to the technical gap in coating technology and groove design at home and abroad, although the bars and knife blanks are of the same material, domestic hard alloy The performance of alloys has always been restricted by large foreign tool brands. At present, according to the physical properties of cubic boron nitride materials and the preparation process of cubic boron nitride blades, it does not require any coating or complex grooves, and its performance is completely determined by its matrix properties, and its own physical properties determine that it has unsurpassed Advantage! Therefore, it will definitely bring about a new cutting technology revolution and serve as a pioneer in the localization of cutting tools.
