Problems solved by technology

[0003] At present, there are many types of working fluids used in wire cutting, including kerosene, emulsion, deionized water, distilled water, washing liquid, alcohol, etc., but these working fluids have some shortcomings, such as lubrication and rust prevention, etc. , especially the emulsion has disadvantages such as easy to stink, difficult to observe during work, and unfavorable to environmental protection
In order to make the working fluid have excellent comprehensive performance, some manufacturers have developed some wire cutting working fluids with good physical and chemical properties by adding several substances at the same time for compounding. Although they meet certain performance requirements, due to the single function traditional additives, which greatly increases the production cost. At the same time, the complex interaction between various additives brings great difficulties to the determination of the formula, which is not conducive to large-scale application

Abstract

The invention provides a novel wire cut electrical discharge machining work fluid and a preparation method thereof. The wire cut work fluid is prepared from the following raw materials in percentage by weight: 48-58% of 20# engine oil, 16-18% of a compound emulsifier, 8-10% of a multifunctional additive, 6-8% of oleic acid, 1.5-2.5% of triethanolamine, 0.5-1.5% of sodium hydroxide and 10-12% of water. The preparation method comprises the following steps: a) preparing the multifunction additive; and b) heating, stirring and mixing the raw materials to prepare the work fluid. The invention discloses the novel wire cut electrical discharge machining work fluid and the preparation method thereof. The wire cut work fluid prepared by adopting a one-step method is simple and feasible and low in cost. The prepared work fluid has good anti-rust property, deforming property, cleaning property and lubricity, is moderate in electric conductivity and free of toxicity and odors and has relatively high application value.

Description

technical field [0001] The invention relates to a working liquid for wire cutting, in particular to a novel working liquid for wire electric discharge cutting and a preparation method thereof, belonging to the technical field of wire cutting electric discharge processing. Background technique [0002] WEDM is a non-contact, special processing method without significant mechanical cutting force. It uses the instantaneous local high temperature generated during the pulse spark discharge between the electrode wire and the workpiece to ionize the medium between the discharge points on the surface of the workpiece. Wear, the metal is melted, gasified and cut into shape. Wire EDM has many unique advantages, and can process various difficult-to-machine and unmachinable materials as well as complex-shaped workpieces. With the rapid development of metal processing industry, wire electric discharge cutting technology has also been greatly developed. In wire electric discharge cuttin...
