Problems solved by technology

At present, the diameter of the wire cutting electrode wire is generally between 30 microns and 50 microns. However, when it reaches this order of magnitude, its tensile strength will be significantly reduced and the durability will be poor, especially when the diameter is less than 30 microns. , its tensile strength will be significantly reduced, and it is difficult to meet the requirements of practical applications

A twist of the carbon nanotube wire ranges from 10r / cm to 300r / cm. A diameter of the carbon nanotube wire ranges from 1 micron to 30 microns. The metal layer is coated on an outer surface of the carbon nanotube wire, and a thickness of the metal layer ranges from 1 micron to 5 microns. A wire cutting device using the wire cutting electrode is also provided.

Description

technical field [0001] The invention relates to a wire cutting electrode wire and a wire electric spark cutting device using the wire cutting electrode wire. Background technique [0002] In recent years, with the rapid development of machining technology, wire-cut EDM has also developed rapidly as a special precision machining technology. The basic principle of wire electric discharge cutting is to use continuously moving thin metal wires as tool electrodes, and a pulsed discharge is formed between the tool electrodes and the workpiece to corrode the workpiece to realize processing. Wire EDM has the characteristics of high processing precision, miniaturization, high efficiency, and low processing cost. [0003] Wire cutting electrode wire plays an important role in wire electric discharge cutting. Wire cutting electrode wire needs to have the characteristics of good wear resistance, high temperature resistance, good surface roughness, good corrosion resistance, high tensi...
