Definition About the Strength of Diamond Grinding Wheel

Diamond grinding wheels are grinding wheels with industrial diamonds bonded to the periphery that are used for grinding extremely hard materials. The strength of diamond grinding wheels includes tensile strength, flexural strength, compressive strength and the strength of resistance to chicken out. The tensile strength of abrasives shows the strength of abrasives under the maximum tensile stress, which is a secondary indicator in abrasives manufacturing, and is directly related with the strength of abrasives rotating in high speed.

The flexural strength of diamond abrasives shows the maximum bending stress or permissible bending limit. When abrasives are forming grinding way, they are required with good flexural strength that is able to resist the bending stress when grinding, such as thread grinding, crankshaft grinding and all types of plunge grinding, etc. 

The compressive strength of abrasives shows the ultimate strength under the pressure. For example, when the radial load of diamond grinding wheel is growing, the fracture and fracture degree of abrasive grain are related to the compressive strength.

The strength of resistance to chicken out of diamond abrasives shows its performance of the resistance to chicken out under dynamic load. The strength of abrasive comes from abrasives manufacturing technology, coupling agent and abrasives specifications. The factors that are related with the strength of abrasives are: types of abrasive, grain size, the varieties of coupling agent and the performance, organization, density, mixing and heat treatment conditions of the abrasives, shape of abrasives, the ratio of diamond grinding wheel diameter and pore diameter, etc.
