Product Description
What are CBN Grinding Wheels?
At a glance, CBN grinding wheels grind the hardest materials known to man. CBN is an acronym for "cubic boron nitride" and is the second hardest material known to man, right behind diamond. It has high abrasion resistance and thermal conductivity against high temperatures - making it better than diamond when grinding for long periods in high temperatures.
It has a cubic crystal lattice, with its atoms arranged in a symmetrical, cube-shaped structure, very much like the crystalline structure of a diamond. Its material properties include extreme hardness, stability under heat, and superior chemical resistance.

About Vitrified Bonds
The bond of a CBN grinding wheel is what holds the abrasive material in place. Most vitrified wheel bonds consist mainly of naturally occurring raw materials like kaolin, feldspar and glass frits - all of which are subject to variations in quality. That's why we use fully synthetic recrystallized glasses in the bonding systems of our vitrified CBN grinding wheels.
Our partially crystallized glass bonds have higher inherent strength than bonds of naturally occurring raw materials and can be used in smaller quantities. This allows for a 10% overall reduction in bond material and a simultaneous equal increase in porosity - without any loss of wheel strength.
Vitrified Diamond and Vitrified CBN grinding wheels combine the hardest known superabrasives held mechanically and chemically in glass (ceramic bond) to form some of the most highly efficient grinding products available on the market.
The combination of the vitrified bond's high thermal stability and its ability to control wheel structures allows for more effective coolant delivery to the grinding zone, resulting in minimization of thermal damage to the work piece.
Most commonly employed in the grinding of PCD and PCBN tools, Vitrifed Diamond grinding wheels have enabled polycrystalline tool fabricators to obtain excellent surface finishes, quickly and productively. Vitrified grinding wheels can also be used in the fabrication of natural diamond, as well as many dense ceramic materials.
The very nature of vitrified bonds allows for the custom tailoring of a grinding wheel structure specific to a customer's material and grinding process, resulting in an efficient grinding process where wheel life and cycle times are optimized for lowest costs and highest work piece quality.
