Problems solved by technology

[0003] However, the WEDM fluids provided on the market for many years are basically emulsified or microemulsified fluids blended with mineral oil as the base oil. However, since this type of wire-cutting machining fluid is prepared with many additives such as sodium nitrite or heavy metals, these substances are not only carcinogenic, but also the discharge of working fluid waste It also causes great pollution to the environment

Abstract

The invention relates to a method for preparing electrical discharge machining liquid. The method includes steps: (1) dissolving 1 part of ammonium borate, 2 parts of sodium carbonate, 1 part of calcium chloride, 4 parts of lauric acid and 1 part of hydroxypropyl methyl cellulose in water; (2) well stirring 22 parts of polypropylene glycol compatibly, and adding into a solution obtained at the step (1); (3) after 30 minutes, adding 2 parts of stearic acid into a solution obtained at the step (2), stirring for 20 minutes, and finally adding 0.1 part of silicone emulsion to obtain the electrical discharge machining liquid after quality inspection is passed. All additives of the novel completely-synthesized wire cut electrical discharge machining liquid are additives high in biodegradation speed, so that the machining liquid is environment friendly and avoids the problem of environment pollution. In addition, the machining liquid is free of physiological toxicity, thereby being novel completely-synthesized wire cut electrical discharge machining liquid which is favorable and free of environment pollution.

Description

technical field [0001] The invention belongs to the field of special lubricating oil for the metal processing industry, and relates to an electric discharge wire cutting metal processing fluid, in particular to a preparation method of the electric discharge machining fluid. Background technique [0002] 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 carried out in WEDM machining fluid so that its performance can be stable. Otherwise, its cutting speed, machining accuracy, surface roughness and other technological indicators will be greatly affected. Therefore, the requirements for EDM machining fluid are getting higher and higher. Wire EDM machining fluid is mainly composed of lubricant, rust inh...
