Thermal growth in spindles acting as a barrier in high speed machining technology. As speed of spindle increases, simultaneously heat generated at the tool-work-piece contact tends to elongate the spindle. This elongation effects accuracy and repeatability of high-speed machines. In this paper thermal growth of spindle neutralized upto maximum extent so as to enhance the performance of machines at higher speeds. This paper aims at studying the behavior of CNC machine tools spindle by utilizing different cooling medias like air, water, coolant, hydraulic oils of different grade and different refrigerants. Here, we have studied the behaviour of CNC machine tools spindle by utilizing different cooling medias like air, water, coolant, hydraulic oils of different grade and different refrigerants to reduce thermal growth. First, spindle rotated at various speed cooled by forced air. Second, spindle cooled with water Third, spindle cooled with coolant. Fourth, rotating spindle cooled with hydraulic oils having different viscosity i.e. 23 nos. and 68 nos. Fifth, spindle cooled with different refrigerants i.e. R-134 a and R-717. Finally, an analytical study along with experimental investigations carried out to prove out the validity of the proposed model.
