GRINDING PROCESS

Grinding Process Grinding is a surface finishing operation where very thin layer of material is removed in the form of dust particles. Thickness of material removed is in range of 0.25 to 0.50 mm. Tool used is a abrasive wheel Grinding machine is a power operated machine tool where, the work piece is fed

Grinding Brittle Materials

The concentration of grit defines the number of diamond particles in the wheel for a particular grit size. A concentration of 75-100 is com-mon for wheels used in grinding brittle materials. This concentration is ideal for maintaining minimal surface damage and optimal wheel performance. Table 1
