PCBN blade, also known as polycrystalline cubic boron nitride blade, is a kind of ultra-high hardness CNC tool. When cutting wear-resistant materials, its wear resistance is about 50 times that of cemented carbide tools. It is especially suitable for processing. The grinding of high-hardness workpieces realizes the effect of using cars instead of grinding.

　　So, how are PCBN blades made? What is the manufacturing principle of PCBN blades? Today Bot Tool will reveal the secrets for everyone, and talk about the manufacturing process and classification of PCBN blades.

　　Generally, there are two main methods for making PCBN blades: ①The primary polymerization method, that is, directly use hexagonal boron nitride (HBN) to polymerize into a high-density sintered body; ②The secondary polymerization method, first synthesize high-density cubic boron nitride ( CBN), and then sintered into polycrystalline cubic boron nitride (PCBN) by high temperature and pressure sintering with it as a raw material.
