Bonds:
In addition to the grit size and concentration, the bond decisively determines the performance and behaviour of the Diamond and cBN wheel. Various adapted bonds rovide optimum solutions for numerous different grinding tasks. They are distinguished based on their binder materials, which in turn contain numerous alloy types.
Grinding Agents:
Diamond is the hardest material known (8000 Knoop hardness) and is suited for grinding of material with at least part of crystaline content. cBN is the second hardest material known (4500 Knoop hardness) and is suited for grinding material without crystalline content.
