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 with PCBN Tooling
1999Material removal, at economic rates, from hardened workpieces has always presented a challenge and, until quite recently, abrasive machining processes were the only option for hard-facings. However, cutting tools based on polycrystalline cubic boron nitride (PCBN) have opened up the possibility of turning and milling as attractive alternatives for ...

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

Fracture Properties of PCBN as a Function of Loading Rate
Key Engineering Materials, 2009Polycrystalline Cubic Boron Nitride (PCBN) is a superhard material which is used in machining of hardened steels and other abrasive and aerospace grade alloys. In these applications the tools are subjected to high operating temperatures, abrasive and impact loading. Impact loading can lead to the sudden fracture and hence failure of the tool.
