Diamond and CBN (Cubic Boron Nitride) abrasives

Diamonds and CBN (Cubic Boron Nitride) are the two main cutting crystals used in super abrasive honing stones. They have their own specific advantages and the choice of cutting abrasive can make a significant difference to the honing process. Selecting the right abrasive for the application is part of the expertise we bring.


CBN (Cubic Boron Nitride)

CBN is the second hardest material, after synthetic diamond, and is particularly suitable for machining ferrous materials. Desirable characteristics of a super abrasive include hardness, strength, abrasion resistance, and thermal and chemical resistance. Essential is the ability to maintain sharp cutting edges during use. These characteristics far exceed the values of conventional abrasives, such as silicon carbide and aluminium oxide.

Hardness is a crucial property of any abrasive. However, most abrasives suffer a loss in hardness at the elevated temperatures experienced during application. One of the physical advantages of CBN, compared to conventional abrasives, is that, in addition to being harder at ambient temperature, it maintains its harness over a wide temperature range.
