Problems solved by technology

The variety of oil working fluids is complex and low in quality, and the color tends to turn dark and yellow after use; sometimes there are pungent odors such as burnt and paint smells; acidified sulfides and sludge are produced quickly, and the risk of mold rusting increases. This will result in poor chip removal and carbon deposit removal of the media, making it impossible to guarantee stable machining accuracy.
In addition, although the existing electric discharge machining oil has a relatively fast rough machining and rough corrosion rate, its high aromatic content (5%-26%) also has a dissolving and irritating effect on the skin
[0004] With China's high-end precision manufacturing and aviation industry's requirements for mirror processing of specific new alloy material products, a new generation of high-end EDM mirror processing machine tools has come out. Meet the needs of mirror processing

Abstract

The invention relates to the technical field of grinding oil, and especially relates to a mirror discharge machining oil and a preparation method thereof. The mirror discharge machining oil comprises n-alkane, isoparaffin, sorbitan oleate and benzotriazole. The preparation method of the mirror discharge machining oil comprises the following steps: S1, adding n-alkane into a container, and stirring until the n-alkane is uniform and transparent; S2, putting sorbitan oleate and benzotriazole into the container, and stirring to be uniform and transparent; and S3, adding isoparaffin into the container, and stirring until the isoparaffin is uniform and transparent. The mirror discharge machining oil disclosed by the invention not only can meet the basic requirements of mirror surface products during discharge machining, but also is colorless, odorless, not easy to oxidize and long in service life, has excellent corrosion and corrosion resistance to nonferrous metals and ferrous metals, and ensures the machining precision.

Description

technical field [0001] The invention relates to the technical field of mirror surface machining oil, in particular to a mirror surface electric discharge machining oil and a preparation method thereof. Background technique [0002] EDM oil has a direct impact on process indicators such as machining efficiency, machining accuracy, and electrode loss, and more and more attention has been paid to the environmental protection, safety, and service life of the working fluid itself. [0003] At present, according to its source and composition, EDM oil can be roughly divided into two categories: oil-based working fluid and water-based working fluid. The variety of oil working fluids is complex and low in quality, and the color tends to turn dark and yellow after use; sometimes there are pungent odors such as burnt and paint smells; acidified sulfides and sludge are produced quickly, and the risk of mold rusting increases. This will result in deterioration of chip removal and carbon...
