According to the processing requirements of petroleum drilling pipe screw-thread,the base oil,emulsifier,oily agent,extreme-pressure agent,anti-rust agent and additives required by a micro-emulsion cutting fluid for thread machining were selected.The formula was optimized by orthogonal tests.The extreme pressure and lubrication performances were test-ed by four-ball test method and tapping torque method,and practical application was studied.The results show that the mi-cro-emulsion developed for thread machining possesses excellent performances on lubricity,extreme pressure,anti-rust, cooling and cleaning.The developed product has the equivalent of all indicators with the imported similar product,which can meet the machining requirements of different grades of steels,and show obvious advantage in improving the surface quality of drilling pipe and extending tool life and reducing reject ratio.It has replaced the imported similar product suc-cessfully.
