Description

technical field [0001] The invention relates to an electric spark oil, in particular to an electric spark oil used for electric spark mirror processing and a preparation method thereof. Background technique [0002] EDM oil is a special cooling medium for mold forming machine tools (EDM machine tools, also called electric pulse machine tools). As early as the 1980s and 1990s, most of the traditional EDM used kerosene as the processing medium. Later, from Taiwan, South China to the coast of the mainland and other plastic mold making areas, special EDM oil was used. This is a kind of EDM oil with a viscosity of 1.5 - CH mixture of low viscosity, solvent-based low aromatic hydrocarbons around 3.0. [0003] Currently in mainland China, Hong Kong, and Taiwan, the common EDM oils on the market are complicated in variety and low in quality, and the color tends to turn dark and yellow after use; Sulfide and sludge are generated quickly, and the risk of mold rusting increases, whic...
