Problems solved by technology
[0003] Existing electric discharge machine cutting wires are usually single-phase metal alloys, such as brass coated with different kinds of metals, such as zinc, tin, aluminum, nickel, etc., and are all made of a single zinc-copper alloy to produce β Phase brass EDM cutting wire is the main one, but for the sake of anti-corrosion, it is additionally coated with brass, but the cutting efficiency of brass-coated EDM cutting wire is low; while copper-zinc with γ phase Alloy, although the cutting efficiency is better, but it is brittle, easy to break or break, and there are still great shortcomings in use
In addition, the existing two structures are not effective in promoting the effective flushing of debris from working parts, so how to find a coating system that not only has a good coating system, but also has corrosion resistance and high cutting efficiency, and also has high metal transfer The cutting line of the electric discharge machine of removal rate is the main problem that the designer of the present invention will solve.

Embodiment Construction
[0017] The present invention is a manufacturing method of electric discharge machine cutting wire. The main step is to form a metal alloy. The alloy can be made of brass or steel as the main core, and it can also be used in three parts such as pure copper, brass or copper-clad steel. Different materials directly form the core to form a relatively stable core of the processing line, and then electroplating or inclusion methods are used to form a β-phase brass cladding layer with a zinc content of about 5% to 45% of the specific gravity, while In order to make the EDM cutting wire cut more efficiently, γ-phase brass has a high composition of zinc, with an average specific gravity of about 65%. However, because the γ-phase alloy is extremely fragile, it is almost impossible to cold draw it. The γ-phase alloy material will break and recombine during cold drawing. Therefore, before cold drawing, the γ-phase coating is coated with a thinner layer of brass core by immersion plating or...

The invention relates to a method for manufacturing a cutting line of an electrical discharge machine. The method mainly comprises the following steps that: two or more different metal alloys are combined to generate metal alloys with different phases by means of staged heat treatment; and fractured coating between different metals is generated after coating combination and cold drawing by means of different physical properties between the alloys so as to form the cutting line of the electrical discharge machine which can resist corrosion and has more effective cutting and further reduce production cost to form the more effective cutting line of the electrical discharge machine.
Description
technical field [0001] The invention relates to a method for manufacturing a cutting wire of an electric discharge machine. Background technique [0002] Generally, the EDM cutting wire with higher zinc content is more efficient when cutting. For example, the EDM cutting wire coated with zinc or the EDM cutting wire containing brass alloy coated with high-component zinc will be more efficient. Compared with the electric discharge machine cutting wire with lower surface zinc content, it has more cutting efficiency; γ-phase brass has a high composition of zinc, about 65% on average, and has a relatively good melting point, about 800 degrees Celsius, so it is generally Both are regarded as excellent electric discharge machine cutting wires, and the average zinc content of β-phase brass is 45%, its melting point is about 880 degrees Celsius, and its ductility is good, and it can be processed by simple cold drawing. Yes, so it is used for the cutting wire of the commonly used el...
