Cubic Boron Nitride - Grits - Parameters

To select the right CBN for tool manufacturers, there are two factors to be taken into consideration. One is strength of the particles, the other is crystal shape.

The strength can be evaluated by the popular TI/TTI test. The TI showed the strength of particles at room temperature. The TTI can reveal reduction in impact strength after heating the abrasive at high temperature. The test could determine the bond to be used for a specific product.

Crystal shape determined the fracture mechanism of different products. Meanwhile, crystal shape could help tool manufacture to choose the bond system of tools.
