Abstract

This paper presents a low temperature nano-lubrication method, using a vortex tube to generate a low temperature grinding environment for increasing heat transfer with a mixture of nanoparticles as a nano-lubricant for reducing friction in ultra-precision grinding of tungsten carbide. The results show the method significantly reduces wheel deterioration and improves workpiece surface integrity. The arithmetical mean height (Sa) and maximum height (Sz) were reduced by 50.8% and 65.3% respectively, with wheel deterioration 57.8% lower than traditional minimum quantity lubrication. These results were obtained by optimized low temperature gas at −20 °C and MoS2/Fe3O4 nano-lubricant with mix-ratio 1:2.
