Grinding is a surface finishing operation, which is capable of producing surface finish as good as less than 1 µm (say, 0.75 µm). In grinding operation (Figure 4.1), abrasive particles remove very thin layer of material producing discontinuous chips like that in milling operation. The abrasive particles held by the bonding material act as ...Web
