Principle of WEDM

  < div > is mainly used to process various complex and precise workpieces, such as punch and die of die. It is developed on the basis of EDM perforation and forming. It has not only developed the application of EDM, but also replaced EDM perforation and forming in some aspects. Wire cutting machine tools have accounted for more than half of EDM machine tools The working principle of wire cutting in < div >: the electrode wire wound on the wire conveying cylinder moves at a certain speed along the rotation direction of the wire conveying cylinder, and the workpiece installed on the machine tool workbench moves relative to the electrode wire according to the predetermined control track. One pole of the pulse power supply is connected to the workpiece and the other pole is connected to the electrode wire. A certain discharge gap is always maintained between the workpiece and the electrode wire, and the working fluid is sprayed. The spark discharge between the electrodes erodes a certain gap, and the workpiece with the required shape and size is cut out by continuous pulse discharge. Technology here, &; Middle wire & rdquo; Although the machining quality of WEDM is better than that of fast WEDM, it still belongs to the category of high-speed WEDM. There is still a large gap between the cutting accuracy and finish and the low-speed WEDM, and the retention of accuracy and finish also needs to be further improved& ldquo; Medium wire feeder & rdquo; It has the characteristics of simple structure, low cost and low use consumption, so it also has its living space. The implementation standard is still the relevant standard of high-speed wire walking machine. Therefore, manufacturers should pay attention to the publicity of users and be realistic
