Coolants and their Role in Grinding

Coolants play a decisive role in grinding because of the intense heat generation and the consequent thermal damage associated with the process. Different types of coolants with varying and diverse compositions are used for grinding different types of work material in order to reduce the heat generated due to friction and to carry away the heat produced as well as for efficient swarf disposal. The present paper aims at discussing about the different types and composition of coolants used in grinding. The mechanism of action of coolants, their application on different workpiece materials and their functions are also discussed in the paper.
