CBN or PCBN stands for cubic boron nitride, which is formed from hexagonal boron nitride under high temperature and pressure. It is a super-hard material that is second only to diamond in terms of hardness. CBN cutting tools are widely used for the continuous cutting of high-hardness and hard-to-machine materials. Our full and solid CBN inserts work perfectly with the process of “turning replaced by grinding”, which improves the processing quality and efficiency of hard workpiece materials.

What areCBNinserts used for

Solid CBN inserts have a great advantage in processing all ferrous materials, making them the first choice for hard turning of the following materials:

Because of its stable physical properties, the efficiency of PCBN for hard turning is 5-10 times of carbide and ceramic inserts.

Turning speeds are adjusted to the feed rate of the mini lathe (0.004/rev.), a depth of cut of 0.040, and a tool life of 180 minutes.
