Water-in-oil Nano Working Fluid for EDM

Abstract

The invention relates to oil pocket water type nano working fluid in the field of electric spark forming machining. The working fluid is composed of white mineral oil, deionized water and compound emulsifier. During preparing, dehydration sorbitol aliphatic ester and lauryl alcohol polyoxyethylene ether are mixed according to the proportion requirement, stirring is conducted till uniform mixing, and accordingly the compound emulsifier is formed. Then, the deionized water, the white mineral oil and the compound emulsifier are mixed according to the proportion requirement, stirring is conductedat the normal temperature till uniform mixing, and accordingly oil pocket water type rough emulsion is formed. Then, the oil pocket water type rough emulsion is arranged in a constant-temperature water bath kettle at the temperature of 80 DEG C, stirring is conducted for 15 min, self-emulsifying of the oil pocket water type rough emulsion is achieved, and finally mixed liquid is arranged at the normal temperature to be naturally cooled. The electric spark forming machining oil pocket water type nano working fluid has the advantages that stability is high, environment friendliness is achieved,usage is safe, the scrap discharging capability is high, machining is efficient, and dielectric strength is high.

Description

technical field [0001] The invention relates to a water-in-oil nano working fluid for electric spark forming processing. Background technique [0002] The working fluid has an important influence on the processing efficiency of EDM, the electrode loss and the surface quality of the processed workpiece and other process indicators. In addition, the modern industry's demand for processing safety and environmental protection also puts forward higher requirements for EDM working fluid. [0003] The working fluids used in the field of EDM can be roughly divided into two categories: oil-based working fluids and water-based working fluids according to their main components. [0004] At present, the more commonly used oil working fluid is kerosene, which has low viscosity and high dielectric strength, which is conducive to the penetration of the working fluid in the processing gap and ensures stable spark discharge. However, from the perspective of safety, kerosene has a low flash...
