This paper presents that the high-speed steel tools with solid lubrication material coating can cut without fluid because it has the quality of self-lubrication. With the help of M-2 friction and wearing testing machine and KYKY2800 scan electron microscope, the coating preparation technology and mixture ratio of solid lubrication material in complex coating can be optimized. The results show: phosphate treatment can increase the power of the tools’ surface adsorbing solid lubricant, and the frictional behaviour of solid lubrication coating is excellent when surface roughness of phosphate coating is Ra 2μm~Ra 4μm; molybdenum bisulfide, graphite and trioxid aluminium are mixed together and form a kind of complex coating which has better antifriction effect. The cutting test shows that the solid lubricant coating on the high-speed steel tools can be helpful in increasing the service life of the tools, decreasing the cutting resistance, and reducing the chip deformation and surface roughness of finished work.
