Abstract. Point grinding is an abrasive machining process that utilizes small diameter superabrasive single-layer grinding tools for accurate machining of complex 3D geometries. Due to the small nature of these tools, high wear-rates and uneven wear around the tool circumference present a challenge for their successful application for the finish …

Profiling and dressing methods may be divided into two classes: stationary methods and methods with rotation of the dressing tool. For grinding wheels based on superabrasive materials, stationary dressing is inapplicable, since the hardness of the abrasive materials—100 GPa for diamond, 80–90 GPa for cubic boron nitride (CBN), …

CBN grains have two main wear modes in high-speed grinding: the macro fracture caused by crack propagation from the rake surface, and the micro fracture near the cutting nose area. The micro fracture occurs more frequently, while the macro fracture requires aggressive overload and enough crack propagation.

Boron carbide powder is a starting material for sintering and hot pressing in the manufacture of boron carbide sintered parts. In this form it can be found, among other things, in dressing and grinding stones and as a lining for ball mills and mortars. Boron carbide powder is also used as a sintering additive for high-performance SiC ceramics.
