[0032] The components and contents of emulsified wire cutting working fluid are shown in Table 2.

Embodiment 12

[0037] The emulsified wire-cutting working fluids of [Examples 1-10] were configured into oil-in-water emulsions with deionized water to evaluate their performance. The concentration of the emulsion is 5% by weight, the volume of the liquid tank is 200 liters, the processing current is 2A, the processing voltage is 75V, and the electrode wire is molybdenum wire. The properties are shown in Table 3.

Abstract

The invention relates to an emulsifying-type linear cutting operating fluid and uses thereof, and mainly solves the problem of short service life of the emulsifying-type electric-spark linear cutting operating fluid in the prior art. The emulsifying-type linear cutting operating fluid comprises the following components: by weight, a) 1-20 parts of a modified rosin blasting agent; b) 2-40 parts of a vegetable oilness agent; c) 0.2-5 parts of a pH adjustment agent; d) 0.1-10 parts of a coupling agent; e) 0.1-8 parts of an emulsifier; and f) 25-80 parts of base oil; the modified rosin blasting agent is selected from at least one from modified rosin prepared by esterification reaction or neutralization reaction of carboxyl in a molecular structure of rosin, or by addition reaction, hydrogenation reaction, disproportionation reaction or polymerization of double bonds of the molecular structure of the rosin, and the technical scheme solves the problem well, and can be used in the industrial production of the emulsifying-type electric-spark linear cutting operating fluid.

Description

technical field [0001] The invention relates to an emulsified wire cutting working fluid and its application. Background technique [0002] With the continuous advancement of industrial technologies such as electronics and automatic control, WEDM has developed into an extremely important processing method and plays an irreplaceable role in the industry. According to statistics, more than 60% of domestic automobiles, tractors, motors, instruments, light industrial electronic products, etc. need mold processing, and a considerable part of them are manufactured by wire electric discharge cutting process. Wire-cut electric discharge machining technology has strong practical value and broad application prospects. It can process conductive materials with almost any hardness, and the machining process is not affected by macroscopic forces, which can ensure better machining accuracy and surface quality. [0003] Different from ordinary cutting, WEDM uses moving thin metal wire (cop...
