摘要

Hardened steels (45~68HRC) are utilized in a multitude of applications ranging from power traincomponents, bearings, and gear shafts etc.The exceptional hardness, good thermal resistance, and high thermal conductivity of polycrystalline cubic boron nitride (PCBN) have helped it thrive in machining of hardened steels for several years.A new series of PCBN grades focused on hard part turning is presented in this paper.The emphasis of the research was on improvement in tool life, productivity and hence reduced part cost for hard part turning applications.The new PCBN grades demonstrate improved crater wear resistance and edge toughness corresponding to applications ranging from continuous to interrupted turning.
