Grinding of PCBN cutting inserts
International Journal of Refractory Metals and Hard Materials, 2014Abstract 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, 2023Cubic 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, 2015PCBN-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

Numerical Investigation into Dynamic Fracture of PCBN
Key Engineering Materials, 2011Polycrystalline Cubic Boron Nitride (PCBN) is a super-hard material, which is used in some of the most demanding material removal operations today. PCBN cutting tools are employed in turning of hardened steels as well as machining of other abrasive and aerospace grade alloys. In these applications the tools are subjected to high operating temperatures,

Cutting Edge Preparation of PCBN Inserts
Advanced Materials Research, 2013In order to increase tool life and workpiece surface quality, cutting processes with geometrically defined cutting edges demand inserts with a targeted prepared edge. For example, chamfers are largely used in many processes to provide edge strengthening without damaging the chip flow. In order to achieve a stable and reliable cutting process, small and

Hard turning of GCr15 steel with chamfered PCBN tools
International Journal of Manufacturing Research, 2013This work investigates the cutting performance of chamfered PCBN tools in hard turning of GCr15 bearing steel. Experimental study was performed on a NC lathe. Cutting forces were measured by using a dynamometer. Cutting temperature was measured by using an infrared thermal imager. The variation of cutting forces and cutting temperature with the chamfer
