Fullerene-based wire cut electrical discharge machining water-soluble composite working solution and preparation method thereof

Abstract

The invention discloses a fullerene-based wire cut electrical discharge machining water-soluble composite working solution and a preparation method thereof. The working solution is prepared from the following raw materials in percentage by mass: 0.01%-1% of fullerene, 20%-40% of a water-based antirust agent, 5%-10% of a cleaning agent, 5%-10% of a blasting agent, 0.5%-1% of a corrosion inhibitor, 1%-5% of a bactericide, 0.5%-3% of a surfactant, 0.5%-5% of an anti-freezing agent, 0.1%-3% of a defoaming agent and the balance of purified water, wherein the total mass percent is 100%. The composite working solution has the characteristics of high processing efficiency, good deslagging and anti-rust performance, long service life, clean workpiece surface, low surface roughness and the like, and meanwhile, the composite working solution is pure water and is environment-friendly.

Description

technical field [0001] The invention relates to the field of fine chemical industry, in particular to a fullerene-based water-soluble composite working fluid for electric discharge wire cutting and a preparation method. Background technique [0002] Wire-cut electric discharge machining is to use wire-shaped electrodes to cut conductive workpieces by spark discharge, so it is called wire-cut electric discharge. It is mainly used in mold manufacturing, trial production of new products, and processing of precision parts with complex shapes and so on. Wire-cut electric discharge machining has the advantages of small machining allowance, high precision, low production cost and short production cycle, and is widely used in automobiles, home appliances, light industry, aviation and other fields. The principle of WEDM is to use reciprocating thin metal wires as tool electrodes to perform pulse spark discharge on conductive workpieces, which will generate electrical corrosion to er...

AI Technical Summary

Problems solved by technology

[0004] 1. The surface roughness Ra of the processed workpiece is generally high, generally higher than 0.9

[0005] 2. The processing efficiency is low, the overall efficiency of cutting one and trimming two is generally 4500mm 2 / h

[0006] 3. The service life of the composite working fluid is short, generally after 15 days, the effect will deteriorate sharply

[0007] 4. The slag removal ability is poor, and the workpiece is easy to rust, etc.
