Performance Evaluation of Natural Additives Coolant for Grinding Process

Arul Nicholas .T, V.E.Annamalai

In grinding process, to remove small quantity of material it consumes high specific energy and produces high temperature in the cutting zone. Heat generation in grinding is due to the shearing of material and friction, which directly influences the workpiece quality. This heat should be controlled within the limit by proper lubrication and cooling. For this purpose cutting fluid is applied during grinding. The main function of cutting fluid is to lubricate as well as to remove the heat. In most of the industries, synthetic cutting fluid is used due to its good lubricating and cooling properties. But on the other hand, they have a significant health and environmental hazard throughout their life cycle. The main aim of this work is to develop an eco-friendly coolant based on bio-degradable additives with water as base coolant. Performance of this novel coolant is compared with existing conventional coolant in grinding application.
