Problems solved by technology

At present, kerosene is still widely used in EDM in my country. Its main advantages are high dielectric strength, low viscosity and good fluidity. Its disadvantages are low flash point, high volatility, poor safety, and easy to cause fire accidents. Harmful gases, etc. are decomposed during processing
Special mineral oil can overcome some shortcomings of kerosene, but this type of mineral oil contains a certain amount of aromatic hydrocarbons, which leads to poor safety of oil products, odor, and irritating effect on the skin
Deionized water has the advantages of low cost, non-flammability, and no pollution to the environment. Many scholars at home and abroad have studied deionized water or deionized water with certain additives as EDM working fluid. At present, this type of working fluid is mainly suitable for Micro electric discharge machining is not suitable for electric discharge forming processing, the main reason is that the processing efficiency is low, and it is easy to corrode the machine tool and workpiece

Abstract

The invention relates to a water-in-oil type electric spark machining working solution in the field of non-traditional machining, comprising compound emulsifying agent, engine oil and deionized water. The working solution is prepared by the following steps: sorbitan monoleate and polyoxyethylene sorbitan monostearate are put together in proportion, stirring for the sorbitan monoleate and the polyoxyethylene sorbitan monostearate to mix and react and form the compound emulsifying agent; the prepared compound emulsifying agent is added into the engine oil according to a required proportion, stirring for the compound emulsifying agent to be dissolved into the engine oil and form an engine oil colliquefaction solution; and the deionized water is added into the engine oil colliquefaction solution, stirring to obtain the water-in-oil type electric spark machining working solution. The water-in-oil type electric spark machining working solution has the advantages of high dielectric strength, safe use, no pollution and high electric spark machining efficiency.

Description

technical field [0001] The invention relates to a water-in-oil type electrical discharge machining working fluid in the field of special machining. Background technique [0002] At present, the working fluids commonly used in EDM at home and abroad include oil-based working fluids and water-based working fluids. [0003] Oil working fluids mainly include kerosene, special mineral oil, synthetic oil, etc. At present, kerosene is still widely used in EDM in my country. Its main advantages are high dielectric strength, low viscosity and good fluidity. Its disadvantages are low flash point, high volatility, poor safety, and easy to cause fire accidents. Harmful gases are decomposed during processing. Special mineral oil can overcome some shortcomings of kerosene, but this type of mineral oil contains a certain amount of aromatic hydrocarbons, which leads to poor safety of oil products, odor, and skin irritation. Synthetic oil mainly refers to normal alkanes and isoparaffins. S...
