Although generally one pass is sufficient, a second pass may be necessary for improved surface finish. 17.4 Grinding Wheel Wear The wear of a grinding wheel can be caused by three actions: attrition or wearing down, shattering of the grains, breaking of the bond. In most grinding processes, all three mechanisms are active to some extent.Regardless of the mechanical approach, whether it is to beat, grind, shear, or explode cells, they are tools that can be applied in many different ways to sample preparation. For simplicity, the methods used for sample disruption have been divided into four groups: grinding, shearing, beating, and shocking.
