Under the high temperature in grinding, abrasive particles will be worn due to plastic deformation. Plastic damage mainly depends on the hot hardness of the workpiece. The abrasive grinding wheel plastic wear occurs if the hot hardness on the rake face of abrasive grain is greater than where in the abrasive contact area. 5. Thermal stress damage.

Nov 01, 1971· An investigation of attritious and fracture wear of grinding wheels in precision grinding is described in a two paper sequence. Attritious wear, the subject of this first paper, refers to the dulling of the abrasive grain due to rubbing against the workpiece surface. The amount of dulling, measured by the area of the wear flats on the surface of …
