One of the key properties of abrasives is their hardness; they must be harder than the materials being machined. The hardness of various abrasives is commonly measured using the Mohs scale. Another important property of abrasives is toughness, which can be tailored by adjusting factors such as the composition, purity, particle size, and crystal structure of the raw materials, thereby optimizing performance for diverse applications.

Cubic boron nitride abrasives are used for gear grinding.
The process capabilities of modern gear grinding machines can increase the volume of hardened gears that can be produced. However, surface defects arising when grinding with conventional abrasive tools remain a significant barrier, preventing the full realization of productivity potential. Surface‑subsurface tempering burns and quench‑induced tempering burns reduce the post‑grinding strength of gears by 20% to 40%, thereby compromising their service performance.

Introduction to the Main Properties of Cubic Boron Nitride (CBN)
In cubic boron nitride (CBN) crystals, nitrogen and boron atoms are sp³-hybridized to form CBN, with a structure analogous to that of diamond. Polycrystalline cubic boron nitride (PCBN) is produced by sintering CBN single crystals—either with or without a binder—under high temperature and high pressure.
