Grinding of PCBN cutting inserts

International Journal of Refractory Metals and Hard Materials, 2014
Abstract PCBN cutting inserts have been more often used in order to attend to the demands of an economically viable process and to lead to a proper workpiece surface quality. A proper application of this cutting material requires its adequate processing. Plunge-face grinding is used for finishing the inserts after sintering.

Development of Low PcBN Composites by SPS

Euro PM2023 Proceedings, 2023
Cubic boron nitride (cBN) is normally used as the hardest phase of composites, together with ceramic and/or metallic matrixes, to form PcBN (Polycrystalline cubic Boron Nitride) materials applied in machining and finishing operations. While high PcBN (70–90 vol% cBN) is only produced by HPHT (High Pressure High Temperature) techniques, low PcBN (40–70 ...

Wear Mechanisms in Grinding of PCBN

Advanced Materials Research, 2015
PCBN-inserts have a high potential in the cutting of hardened steel, cast iron and super alloys due to their high hardness and heat resistance. Nevertheless they have a high purchase price, which lowers the economic benefits for the end user compared to other cutting materials. This is caused by the high production costs of the inserts. The grinding of
