Characteristics Of PCBN Cutter
- Apr 27, 2017 -

CBN has high hardness, chemical inertia and thermal stability under high temperature, so as abrasive CBN grinding wheels are widely used in grinding. Since the CBN has a characteristic superior to other tool materials, people are trying to apply it to cutting machining at the outset, but the small crystal CBN particles, it is difficult to make knives, and CBN sintering is very poor, difficult to make larger CBN sintering, until in the 1970 of the 20th century, the former Soviet Union, China, the United States, the United Kingdom and other countries have developed successfully as a cutting tool of CBN sintering-poly-crystalline cubic boron nitride PCBN (Polycrystalline Cubic Boron Nitride. Since then, PCBN with its superior cutting performance applied in various fields of cutting machining, especially in high-hardness materials, difficult-processing materials in the cutting process is unique. After more than 30 years of development and application, now has emerged for the processing of different materials of the PCBN cutter material.
