Solid CBN Inserts For Hard Turning

PCBN tool is an artificial cubic boron nitride tool, which can maintain high hardness at high temperature, and is mainly used for processing iron parts. Cubic Boron Nitride CBN (Cubic Boron Nitride) was first synthesized by General Electric (GE) in the United States in the 1950s using artificial methods under high temperature and high pressure conditions. Its hardness is second only to diamond and much higher than other materials. Therefore, It and diamond are collectively referred to as superhard materials.

Features:
CBN has high hardness, chemical inertness and thermal stability at high temperature, so it is widely used in grinding as an abrasive CBN grinding wheel. Because CBN has better properties than other tool materials, people have tried to apply it to cutting at the beginning, but the particles of single crystal CBN are small, making it difficult to make tools, and CBN has poor sintering properties, making it difficult to make relatively For large CBN sintered bodies, it was not until the 1970s that the former Soviet Union, China, the United States, the United Kingdom and other countries successively developed CBN sintered bodies as cutting tools—Polycrystalline Cubic Boron Nitride PCBN (Polycrystalline Cubic Boron Nitride). Since then, PCBN has been used in various fields of machining with its superior cutting performance, especially in the machining of high-hardness materials and difficult-to-machine materials. After more than 30 years of development and application, PCBN tool grades for machining different materials have emerged.
