In order to optimize the surface quality of ultra-precision cutting pure tin,this paper determines that the cutting liquid type of cutting pure tin material is a mixture of alcohol and isomeric alkane through the evaluation and study of various types of cutting fluid. Then,cutting experiments are conducted on different cutting liquid ratios,and real-time ob-servation of surface morphology and surface roughness is carried out by white light interferometer. The data of surface de-fects and surface roughness are analyzed statistically. The experimental results show that under the same cutting parameters,the optimal cutting fluid ratio of ultra-precision turning pure tin with diamond tool is within the range of 20％ alcohol con-tent and 80％ iso-paraffin cutting fluid content. The optimal cutting fluid ratio of ultra-precision turning pure tin with car-bide cutting tool is in the range of 60％ to 80％ alcohol content and 20％ to 40％ iso-paraffin cutting fluid content.
