A Comparative Study of Grinding Performance Using Different Fluid Delivery Techniques

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.
