Grinding is a more universally known process. Most workpieces can be ground, independent of their shape. Hard turning, on the other hand, has geometric limitations, as is the case with long and thin components. Wide surfaces can be finished effectively, often with a single plunge grind operation. In addition, with grinding a turn-free surface ...

Grinding. Machining is one bulk material removal process (i.e. high MRR). Thus it is economical and suitable to give proper size and also for semi-finishing. Grinding has low material removal rate and is preferred only for finishing. Accuracy and tolerance achieved by conventional machining operations are not so good.

The principle of internal grinding is shown in Fig. 3. Internal grinding helps to grind the surface of bores whether they are plain or tapered with the help of a small grinding wheel. This process improves the geometry of the hole as well as the surface finish. A softer wheel is used for internal grinding. 8.
