CBN inserts is the use of artificial methods used in high temperature and pressure conditions, cubic boron nitride powder and a small amount of binding agent synthetic, its hardness only to diamond which is much synthetic diamond other materials, so it is with the diamond tool referred to as super-hard tool. It has high hardness, thermal stability and chemical inertness, thermal stability, which is much higher than diamond, abrasive grinding metal element has a greater Polycrystalline diamond, so commonly used in the cutting of ferrous metals. CBN inserts used metalworking is a major contribution, resulting in revolutionary changes cutting, cutting technology is the second leap.
