When honing high hardness and toughness materials, the Diamond /CBN Efficiency of honing stone( stick) is 3-75 times higher than that of ordinary abrasive stone, and the honing efficiency of ordinary materials is also improved about 10 times. since Diamond/CBN honing stone (stick) wear is less, the shape retention is better, therefore, the higher honing accuracy and economic effect can be obtained.
