Grinding being a operation in which the cutting takes place by abrasion the heat produced is much higher. This heat when goes to the component surface it leads for the problems like surface cracks, Re-hardened & tempered layers, which are no good for the life of the component. Hard Turning being single point turning & CBN being an excellent thermal conductive material negligible heat is transmitted to the component surface. So many a times Hard Turning is preferred to solve the surface Integrity Problems faced in Grinding.
