摘要：
The present disclosure relates to cubic boron nitride (cBN) cutting elements that have high cBN content and that are cuttable by electric discharge machining (EDM). A cutting element according to an embodiment includes a self-sintered polycrystalline cubic boron nitride (PCBN) compact, having a first phase of cubic boron nitride (cBN) particles and a ceramic binder phase with titanium compounds. The first phase occupies greater than 80% by volume of the self-sintered PCBN compact. The self-sintered PCBN compact has an electrical conductivity sufficient to be cuttable by electrical discharge machining.
