Different workpiece materials, and its fracture toughness, hardness, and are quite different, so the nature of the material of the workpiece is also affect the wear of the abrasive tools.  studied different stone diamond saw cutting tool wear and pointed out: When cutting hard

Granite, Diamond Saw wear abrasive macro broken and fall off, the reason is not enough holding force, cutting conditions; when cutting softer granite, the complete crystalline form and abrasive micro crushing accounting a large proportion of abrasive off

Off the still high proportion of such wear the blade to keep cutting disc. Xu Xipeng: the nature of the different minerals in the granite and deformation mechanism is to determine the key diamond failure mode. Quartz content is higher, the diamond the more severe wear; syenite

Stone content was significantly higher, the sawing process is relatively difficult to be carried out; under the same cutting conditions, the coarse granularity granite fine granularity than granite it more difficult for cleavage fracture occurs.
