Technical Demands for Grinding Materials

The following discussion is focused on grinding materials for machining steel and cast iron, because these are most important industrially. Two different requirements are to increase working efficiency and to minimize undesirable interactions of the tool with the ground surface. 

In Fig. 8, the improved technical performance of the polycrystalline grinding materials in spite of their almost unchanged hardness seems to disagree with the
