Abstract: The composition and content of emulsifier and antirusting agent were investigated in grinding fluid by investigating the influence of kind and amount of surfactants and antirusting agent on the performance of microemulsion grinding fluid. Microemulsion grinding fluid was prepared and measured. The results showed that the oil removal rate is 95% with emulsifier formed from a mixture of four non-ionic surfactant of 6%. And the optimal composition of antirusting agent is as follows：monoethanolamine 8%，triethanolamine 8%，benzotriazole 0.3%. The antirust performance of microemulsion grinding fluid has reached the Chinese National Standard-the Synthesized Cutting Fluid (GB6144—85).
