Why Diamond Grinding Wheels Are Super-Abrasives

Diamond grinding wheel manufacturers assign the extent of hardness in a wheel. This is achieved by either allowing the abrasive grains to fracture easily or by restricting the fracture. When abrasives fracture easily the wheel is classified as a soft bond. Hard bond wheels can withstand larger forces since the fracturing is restricted.
