Water-based working solution for wire electrical discharge machining and preparation method thereof

Abstract

The invention provides a water-based working solution for wire electrical discharge machining. The water-based working solution for wire electrical discharge machining comprises the following components in parts by mass: 10-15 parts of triethanolamine, 2-3 parts of sodium borate, 1-2 parts of petroleum sodium sulfonate, 5-10 parts of acrylamide, 5-8 parts of sodium stearate, 2-3 parts of polyvinyl alcohol, 1-2 parts of polyacrylamide, 1-2 parts of fatty acid polyoxyethylene ether methyl ester, 0.5-0.8 part of glycerin, 8-10 parts of ethanol and 40-45 parts of distilled water. The invention also provides a preparation method of the working solution. The water-based working solution for wire electrical discharge machining has the beneficial effects that the service life of the working solution is 12-15 days; the working solution has good processing properties; the surface finish of machined workpieces is improved; the working solution is low in environmental pollution, can not produce oil mist, does not corrode machine tools or machine elements and can not cause bad contact of equipment or mildew and rot damages.

Description

technical field [0001] The invention relates to a water-based wire cutting working fluid. Background technique [0002] The performance of machine tool machining fluid not only affects the processing technology indicators that people can intuitively feel, such as cutting speed, surface quality, and surface uniformity, but also affects the stability of processing and the service life of workpieces. [0003] Traditional machine tool processing fluids, especially wire cutting fluids, usually use emulsified oil, but traditional emulsified oil has the following disadvantages: 1) The process performance is poor, for example, the surface finish of the workpiece processed with emulsified oil is average; 2) The service life is long Short, must be replaced once every 7-9 days; 3) Environmental pollution, traditional emulsified oil will turn black and smelly after use, produce a pungent smell, and sodium nitrite and sulfonate, etc., are very harmful to the environment ; 4) The impact ...
