Wire cutting device walks in longmen
Technical Field
The invention relates to wire cutting equipment for electric discharge machining, in particular to a wire cutting device in a gantry.
Background
The wire cut electric discharge machine adopts molybdenum wire or hard brass wire as electrode wire, and under the action of high-frequency pulse voltage, the liquid medium is broken down to form electric spark discharge, and simultaneously heat is generated to locally melt metal on the surface of a workpiece, and simultaneously the cutting liquid washes the cutting part, and the movement of the electrode wire is controlled by a controller to form a preset shape and size on the workpiece. Because the working environment of wire cutting is severe, the corrosion of the working solution is strong, water and scraps are easy to enter the machine tool, so that the machine tool is easy to age, and the electrical failure rate is high. Meanwhile, as the guide wire assembly is usually in a cantilever installation mode, displacement and looseness are easy to occur after long-time use, and the cutting precision is affected. Therefore, there is a need for structural optimization of such cutting machines to overcome the above-mentioned drawbacks.
