High-flash-point electric spark working fluid

Abstract

The invention relates to a high-flash-point electric spark working fluid. The invention is characterized in that the working fluid is prepared from the following steps: (1) dissolving 1 part of trisodium phosphate, 5 parts of ammonium borate, 3 parts of magnesium oxide, 1 part of sodium metasilicate, 1 part of polypropylene glycol and 4 parts of lauric acid in deionized water; (2) uniformly stirring 23 parts of coconut oil fatty acid, adding into the solution in the step (1) while stirring, and stirring uniformly; (3) adding 2 parts of N-amidoamino acid into the solution in the step (2), continuing stirring for 20 minutes, finally adding 0.5 part of polyoxyethylene polyoxypropylene pentaerythritol ether, and inspecting to obtain the qualified electric spark wire working fluid. The working fluid has the function of environment protection, can not cause the problem of environmental pollution, does not have physiological toxicity, and is an ideal environment-pollution-free novel complete-synthesis electric spark wire cutting metal working fluid.

Description

technical field [0001] The invention belongs to the field of special lubricating oil for the metal processing industry, and relates to a wire electric discharge cutting metal processing fluid, in particular to a high flash point electric discharge working fluid. Background technique [0002] Wire cutting electrical discharge machining (Wirecut Electrical Discharge Machining, referred to as WEDM), sometimes also known as wire cutting. Its basic working principle is to use a continuously moving thin metal wire (called an electrode wire) as an electrode to perform pulse spark discharge on the workpiece to etch the metal and cut it into shape. [0003] With the development of metal processing industry, wire electric discharge cutting technology is more widely used. The wire electric discharge cutting tool has many unique advantages, and it can process various workpieces with complex shapes that other tools cannot process or are difficult to process. However, WEDM needs to be c...
