Development of Solid PCBN Grades with Low CBN Content

摘要：

　　The value of low CBN content PCBN tool materials has long been recognized in hardened steels machining, and is increasingly seen as a leading solution for nickel and cobaltbased superalloys.This research presents the development of low CBN content PCBN disks in large solid formats, of up to 91 mm diameter and 12 mm thickness, and presents benchmark machining tests and results which show that the new solid grades can significantly outperform their carbide-backed counterparts.Discussion of the brazing methods and flexibility in tool geometry afforded by these unique formats andthe electrical conductivity of the new materials is also presented.
