Abstract

The purpose of the cutting fluids is to minimize the friction and heat apart from flush away the chips that are generated during machining operation. Further, these fluids are the mixtures of various synthetic, semi –synthetics, straight oils, emulsifiers, additives and biocides. There is also a possibility of contamination of the fluids in any manufacturing concern because of tramp oils, particulate matter etc. Apart from this a serious problem involves with these water based metal working fluids is the development of microbial contamination and its related other products like exo and endotoxins. Foul odor generation, appearance as a sticky substance and unpleasant nature to touch the fluids causes severe health effects to the workers involved in machining operations. In this paper, samples of graphite nano particle suspended fluids prepared with different weight percentages meant to be used in Minimum Quantity Lubrication. These samples stored for one month and then tested during this period to find the type of bacteria present in the cutting fluids and the growth of microorganisms.
