Problems solved by technology

The disadvantages of the former are: the service life is only about 3 months; the flash point is 50°C, the aromatic content is large, above 10%; the viscosity is 1.5
The disadvantages of the latter: Compared with the former, the flash point is high, up to 100°C, but it is easy to form carbon; the content of aromatics is high, below 10%; the service life is still not ideal, about 6 months; sports Viscosity is too high, around 3
[0005] In the literature, for example, in the patent literature, the applicant only retrieved an authorized announcement number of CN1038732C, the name is the electric discharge machining liquid and the electric discharge machining method using this liquid. The technical problem to be solved by the patent technical solution is to improve the The finishing quality of the workpiece makes the surface of the workpiece smooth like a mirror, so it is not as good as the rest of the teaching

Abstract

An electric spark processing liquor belongs to the technical field of electric discharge processing liquor which is formed by mixing solvent oil and tetradecane alkane according to a weight percentage of 1:1 to 2.5. One advantage of the electric spark processing liquor provided by the invention is that the service life can reach 16 to 30 months; a second advantage is that a flash point (cut) can reach 105 to 110 DEG C; a third advantage is that content of aromatic hydrocarbon is low which is equal to or lower than 0.5 percent and the viscosity is suitable with movable viscosity of 2.1mm<2>s.

Description

technical field [0001] The invention belongs to the technical field of electrical discharge machining fluid, and in particular relates to an electrical discharge machining fluid. Background technique [0002] EDM fluid is also called electrical discharge machining fluid, and the English abbreviation for electrical discharge machining is EDM. With the development of industrial production and the progress of science and technology, EDM has been widely used in the processing of products such as aerospace, military industry, electronics, machinery, molds and so on. The mechanism of EDM is a special processing method that controls the formation of conductive workpieces through the electric erosion operation generated when the workpieces immersed in the processing fluid pass through the pulse discharge between the electrodes. When the conductive workpieces are formed, the two electrodes The space must be filled with a liquid medium, which is the aforementioned EDM fluid. The pro...
