  • What Is The Low Speed Wire Cut ?
    Nov 06, 2018

    The common Machining process include CNC Machining, CNC turning, Auto lathe turning, CNC Milling,Stamping, Sheet metal fabrication, Casting, Injection molding etc

     

    Slow wire, also known as low speed wire, is the use of continuously moving thin metal wire (called electrode wire, usually copper wire) as the electrode to carry out pulse spark discharge on the workpiece, resulting in high temperature above 6000 degrees, etch the metal, A NC machine tool that is cut into a workpiece. The principle of slow-moving wire machining is the phenomenon of continuous discharge to remove metal in the gap between the on-line electrode and the workpiece.


    Because the slow walking wire cutting machine adopts the way of continuous wire supply with wire electrode, that is, the wire electrode is processed in the course of moving, so even if the wire electrode is lost, it can be continuously replenished, so the machining precision of parts can be improved. The surface roughness of the workpiece machined by the slow-moving wire cutting machine is usually up to Ra=0.8 μ m or above, and the roundness error, the linear error and the dimension error of the slow walking wire cutting machine are better than those of the fast walking wire cutting machine. Therefore, in the processing of high-precision parts, slow-moving wire cutting machine has been widely used. In addition to early small-and-medium-sized enterprises, processing plants in large companies such as aviation, cars, and healthcare are also common.


    Slow walking wire is a kind of machine tool which uses continuously moving thin metal wire (called electrode wire) as electrode to remove metal from workpiece by pulse spark discharge. There is a loose contact light pressure discharge between the electrode and the workpiece during slow wire processing. When the flexible electrode wire and the workpiece are close to the commonly believed discharge gap (for example, 810 μ m), no spark discharge occurs, even when the wire is in contact with the workpiece and the gap is not visible from the microscope. Normal spark discharge occurs only when the electrode wire is bent and deviated by a certain distance (several microns to several tens microns). When the wire electrode is fed 1 μ m, the discharge gap does not decrease by 1 μ m, but the wire increases the tension between wires a little, and the workpiece increases the lateral pressure. Only when the wire and the workpiece maintain a certain contact pressure can spark discharge be formed. It is concluded that there is a kind of electrochemically produced insulating film dielectric between the electrode wire and the workpiece.
