Including: polycrystalline cubic boron nitride (PCBN) and CVD cubic boron nitride coating.

Among them, artificial diamond composite sheet (PCD) cutter and cubic boron nitride composite sheet (PCBN) cutter dominates.

Many machining concepts, such as green machining, car grinding, milling, hard machining, high-speed cutting, dry cutting and so on are all due to the application of super-hard tools, so super-hard cutting tools have become cutting Lack of important means. PCD and PCBN cutting tools have been widely used in various sectors of machining, such as cutting of automotive parts, laminate flooring processing, which greatly promoted the rapid development of cutting and advanced manufacturing technology.
