Preparation of the electric spark working fluid is characterized by comprising the specific steps of (1), dissolving ammonium borate of 5 parts, magnesium oxide of 3 parts, sodium metasilicate of 1 part, sodium phosphate of 1 part, trisodium phosphate of 1 part, lauric acid of 4 parts and alcohol amine of 1 part into deionized water; (2), making fatty acid of 20 parts compatible, stirring the fatty acid uniformly, adding the fatty acid into the solution in the step (1) in a stirring mode and stirring the mixture uniformly; (3), adding stearic acid of 2 parts into the solution in the step (2), stirring the solution for 20 minutes continuously, adding polyoxypropylene and polyoxyethylene glyceryl ether of 0.3 part into the mixture and finally obtaining the electric spark working fluid if quality inspection is qualified. The electric spark working fluid is friendly to the environment, does not cause environmental pollution and is free of physiological toxicity, thereby being an ideal kind of novel total synthesis wire cut electrical discharge machining metal machining liquid avoiding pollution to the environment.

Description

A kind of to-and-fro thread feed electric spark wire-electrode cutting machine electric spark working solution

Technical field

The invention belongs to metal-working industry special lube field, relate to a kind of Wire EDM metal working fluid, especially a kind of to-and-fro thread feed electric spark wire-electrode cutting machine electric spark working solution.

Background technology

Wire-cut Electrical Discharge Machining (WirecutElectricalDischargeMachining is called for short WEDM), sometimes also known as Linear cut.Its basic functional principle utilizes the fine wire of continuous moving (being called wire electrode) to make electrode, carries out pulse spark electric discharge removal metal, excision forming to workpiece.

Along with the development of metal-processing industry, Electric Discharge Wire-cutting Technology application is more extensive.Wire EDM instrument has the advantage of many uniquenesses, and it can be processed other instruments and cannot process or unmanageable various complex-shaped workpiece.But Wire EDM needs to carry out in Wire-cut Electrical Discharge Machining liquid, and its performance could be stablized, otherwise the technic indexs such as its cutting speed, machining accuracy, surface roughness are all greatly affected.Therefore, also more and more higher to the requirement of Wire-cut Electrical Discharge Machining liquid.Wire-cut Electrical Discharge Machining liquid is primarily of compositions such as lubricant, antirust agent, surfactant, burster and oxidation and corrosion inhibitors, and its main performance requirements is: possess certain insulating properties, fast electric from deionization, good rust-preventing characteristic, good lubricity, good stickiness, good cooling, good washing performance and good oxidation corrosion resistance.

CN102784976A discloses a kind of electric spark processing liquid, and it comprises following component and content: oleic acid: 5-10wt%, fatty acid distribution of coconut oil: 8-12wt%, hydramine: 3-5wt%, additive: 0.5-1.5wt%, and the 68# machinery oil of surplus.Working fluid flash-point of the present invention is high, process industrial art performance good, uses long service life, and does not all have harmful effect to human body and machine.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, a kind of environmental protection, the nontoxic and simple a kind of to-and-fro thread feed electric spark wire-electrode cutting machine electric spark working solution of preparation method are provided.

It is as follows that the present invention realizes object technical scheme:

A kind of to-and-fro thread feed electric spark wire-electrode cutting machine electric spark working solution, concrete steps are as follows:

(1), by ammonium borate 5 parts, 3 parts, magnesia, sodium metasilicate 1 part, sodium phosphate 1 part, tertiary sodium phosphate 1 part, dodecylic acid 4 parts and hydramine 1 part are dissolved in deionized water;

(2), by after compatible for 20 parts of aliphatic acid stirring, under agitation join step (1) in solution, be stirred to evenly;

(3) in step (2) solution, add 2 parts of stearic acid, continue stirring 20 minutes, finally add 0.3 part of polyoxyethylene polyoxypropylene glycerin ether, after quality inspection is qualified, namely obtain wire electric discharge working fluid.Advantage of the present invention and beneficial effect are:

In spark cutting liquid prepared by the preparation method of environmental protection environmental protection electric spark line working fluid of the present invention, additive is biodegradation rate additive faster; this working fluid is made to have the effect of environmental protection; the generation of problem of environmental pollution can not be caused; and this working fluid does not have physiological-toxicity, it is the novel full synthesis Wire EDM metal working fluid of the comparatively ideal environmentally safe of a class.

Detailed description of the invention

Below by specific embodiment, the invention will be further described, and following examples are descriptive, is not determinate, can not limit protection scope of the present invention with this.

A kind of to-and-fro thread feed electric spark wire-electrode cutting machine electric spark working solution, concrete steps are as follows:

(1), by ammonium borate 5 parts, 3 parts, magnesia, sodium metasilicate 1 part, sodium phosphate 1 part, tertiary sodium phosphate 1 part, dodecylic acid 4 parts and hydramine 1 part are dissolved in deionized water;

(2), by after compatible for 20 parts of aliphatic acid stirring, under agitation join step (1) in solution, be stirred to evenly;

(3) in step (2) solution, add 2 parts of stearic acid, continue stirring 20 minutes, finally add 0.3 part of polyoxyethylene polyoxypropylene glycerin ether, after quality inspection is qualified, namely obtain wire electric discharge working fluid.

The using method of this product:

The working solution using producer before use this working fluid concentrate to be deployed into 5% (m/m) can carry out Linear cut production and processing.

Wire EDM metal working fluid of the present invention, integrated performance index all reaches advanced international level, and does not have physiological-toxicity and problem of environmental pollution, is the water base full synthesis Wire EDM metal working fluid of the comparatively ideal environmentally safe of a class.
