Safety measures for grinding machines are, in particular, characterized by guards with interlocking and guard locking, to effectively counteract risks of fracture of ceramic tools. In some special cases of grinding operations, guards can be regarded as disturbing by the operator because they obstruct process monitoring.

This process is known as Dressing of grinding wheel and the whole process takes 15 to 20 minutes to operate. The life of the grinding wheel is described as the time period between two successive dressings. Grinding operation is one of the machining processes which consume the highest specific cutting energy with very less material removal rate.

In grinding process, the process of breaking of abrasive grains & exposing sharp edges is called as friability. When the grains break down under pressure, the new edges for cutting emerge or are exposed. During this process, the binding material also gets removed and the grains which have become blunt get free and are removed.
