Two types of cubic boron nitride tools, BZN6000 (high CBN content) and BZN8100 (low CBN content), have been tested. Overall, BZN8100 shows better performance in finish turning of hardened steel than BZN6000. The results suggest that BZN8100 has greater wear resistance under higher cutting speeds than BZN6000 because of favorable chemical characteristics.(plate) Assessment of Tool Life and Wear Intensity of CBN Tools in wear of cbn tools in ultra(steel) In this paper the formulation developed for CBN tools, applied for the machining of 100Cr6 bearing steel is presented.
