Single crystal diamond or cbn featuring micro fracturing during grinding

摘要

A superabrasive material is provided. The superabrasive material may comprise a superabrasive crystal having an irregular surface. The superabrasive material further comprises a plurality of structure defects within the superabrasive crystal or has a layered or laminar microstructure. The plurality of structure defects may cause micro chipping when used as grinding materials. The superabrasive crystal is selected from a group of cubic boron nitride diamond and diamod composite materials. A method of making boron nitride superabrasive materials is also provided.
