POLYCRYSTALLINE CUBIC BORON NITRIDE
The present disclosure relates to polycrystalline cubic boron nitride (PCBN) with improved fracturing-resistance and wear-resistance. The polycrystalline cubic boron nitride is prepared using CBN particles of different particle sizes. In this way, the bonding force was increased by heat treatment of the second group CBN particles and binder. At the same time, improvements of the dispersion of the CBN particles of the first and second groups and the bonding force between the binder and cubic boron nitrides were achieved at the same time. Thus, the wear-resistance and fracturing-resistance of the PCBN can be effectively improved. Further, according to the present disclosure, preparing the polycrystalline cubic boron nitride by regulating the volume ratio between the charged CBN particles may allow the wear-resistance and fracturing-resistance of the PCBN to be improved. Thus, the machining tools with excellent lifetime can be manufactured using the PCBN.
