Abstract

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.

Keywords

Coolant, Lubrication, Grinding.

Abstract

Grinding fluids, commonly termed as coolants, play a vital role in controlling the heat produced during the process and the consequent thermal damage associated with it. These fluids are to be applied into the grinding zone in a suitable and effective manner, so as to reduce the heat generated and to carry away the heat produced as well as for efficient chip disposal. In this work, three different methods, namely normal flood cooling, mist cooling and multi-nozzle cooling arrangements are employed for delivering the fluid into the grinding zone. A comparative study is made among the three coolant delivery systems to assess the grinding performance. It is found that the multi-nozzle cooling arrangement produces best results in terms of force requirement and ground surface quality.
