Problems solved by technology

[0002] When using CNC cutting machine tools for machining, it is necessary to configure and use working fluid. The use of working fluid can make the processed parts obtain better processing smoothness and correspondingly improve processing efficiency. The traditional working fluid is composed of mineral oil, surfactants and additives. The mineral oil in it is not less than 60%. When used, it is mixed with clean water and diluted to 5%-10% emulsion. The working fluid has good lubricating and antirust functions, and has the effects of dielectric strength, deionization and arc extinguishing. , but the traditional working fluid uses a large amount of mineral oil, resulting in high cost, poor cooling effect, low cutting efficiency, difficult to deal with waste liquid and residue, and easy to cause environmental pollution and other problems

Abstract

The invention provides a cutting working fluid of a numerically controlled line-cutting machine, and a preparation method thereof. The cutting working fluid of the numerically controlled line-cutting machine comprises, by weight, 5-30% of rosin soap, 1-10% of sodium petroleum sulfonate, 5-10% of sodium oleate, 5-20% of triethanolamine, 0.1-2% of sodium citrate, 1-5% of sodium carbonate, 1-5% of trisodium phosphate, 1-10% of phosphate ester, and the balance being clear water. The preparation method comprises a first step of measuring a proportional amount of the clear water according to a formula, putting the clear water in a container and heating to a temperature of 60-80 DEG C; a second step of stirring in the container with a stirrer, adding a formula amount of the phosphate ester under a stirring state and keeping a temperature at 50-60 DEG C to dissolve the phosphate ester; a third step of adding formula amounts of the rosin soap, sodium oleate and sodium petroleum sulfonate under stirring, mixing uniformly and continuously keeping the temperature for 30 minutes; and a fourth step of closing temperature preservation, adding formula amounts of triethanolamine, sodium citrate, sodium carbonate and trisodium phosphate under stirring, and stirring for 5-10 minutes to obtain a brownish red and transparent finished product of the cutting working fluid. The working fluid produced by the method is simple in process and low in cost, and has no discharge of pollution wastes.
