Mechanical electro-spark wire-electrode cutting fluid and preparation method thereof

Abstract

The invention discloses a mechanical electro-spark wire-electrode cutting fluid and a preparation method thereof. The mechanical electro-spark wire-electrode cutting fluid comprises the following raw materials in parts by weight: a spark discharge modifier, an anti-rust agent, sodium carbonate, calcium chloride, dodecanoic acid, hydroxypropyl methyl cellulose, stearic acid, a chip clearing agent, sodium tetraborate, sodium metasilicate, petroleum sodium sulfonate, ricinolein, sulfonated oil, oxalic tetraethylammonium, deionized water and polypropylene glycol. The spark discharge modifier in the mechanical electro-spark wire-electrode cutting fluid can control the spark discharge under large current; the arc extinguishing effect is good; the components of the mechanical electro-spark wire-electrode cutting fluid are not sintered under an instant high temperature; the mechanical electro-spark wire-electrode cutting fluid has excellent cooling property, lubricating property, anti-rust property and chip removal property; the mechanical electro-spark wire-electrode cutting fluid has a function of environmental protection, will not result in environmental pollution problem and is free from physiological toxicity.

Description

technical field [0001] The invention relates to the technical field of electric discharge machining, in particular to a mechanical electric discharge wire cutting fluid and a preparation method thereof. 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. [0003] However, the WEDM fluids provided on the market for many years are basically emulsified or microemulsified fluids blended with mi...

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
