what is pcbn material?

PCBN is made of polycrystalline cbn that is produced in a high temperature-pressure procedure, Cubic Boron Nitride (CBN) Inserts are high-performance tools used for cutting hard materials. Usually, they are very hard, hence suitable for machining materials that can’t be machined by mono-crystalline diamond.

This study provides a proportioning design method for the polycrystalline cubic boron nitride (PcBN) composite based on dense packing theory with the use of the Horsfield dense filling theory and Dinger–Funk equation. Subsequently, three proportioning schemes of the cBN–TiN system were designed with different titanium nitride content.
