High-speed machining has emerged as a contemporary technique for manufacturing automotive parts. Accelerating the production process through milling with nano-fluid cooling via an inter-tool channel introduces a novel method to enhance both the durability and the quality of milling operations. This study examines the application of nano-fluids based on nano-diamonds, water-ethylene glycol, and water-propylene glycol in the intercooling systems of milling tools for automotive part production, Through COMSOL simulation, the results reveal that adding 5% nanofluid enhances the heat transfer coefficient by over 13%. Enhancing the concentration of nanofluid improves heat transfer efficiency, leading to a more rapid reduction in fluid temperature. Specifically, nanodiamond-based nano-fluids yield a 2% increase in the heat transfer coefficient, while ethylene glycol-based and water-propylene glycol-based nano-fluids achieve an 8% improvement. Among the tested options, propylene glycol-based fluids emerge as the optimal choice for tool cooling. By reducing the temperature in the machining zone significantly, these fluids effectively enhance the service life of cutting tools.
