In this work it was performed a fluid flow study of lubricant and cooling systems in machining process. In machine tools industry is very important to reduce the costs when are using the lubricant and coolant fluids to increase the productivity. It was been performed a simulation of the fluid flow through a nozzle, that nozzle type is commonly used for pressure cooling of the machined area. In these types of nozzles can be made a mixture of two types of fluids, such as air and water, to increase machined productivity and decrease the quantity of lubricant used for cooling systems.
