What is the difference between Wire EDM and EDM
The processing principle of wire EDM and EDM itself is the same, both use electrodes to corrode the workpiece, remove a part of the metal, and get the shape we need. Any shape can be processed. It is precisely because it is through up and down, so, especially when machining a whole shape or inner hole, especially when machining a shape, such as a gear, if the external allowance is relatively small, due to the workpiece. The inability to perform threading hole processing leads to two clamping operations. Since the workpiece must be clamped with a small tooling at one end, this blessing part cannot be cut by wire, which is also one of the biggest drawbacks of wire cutting. We often encounter this kind of trouble in the process of processing. Of course, this problem is not encountered in reciprocating wire cutting, including low-speed wire-feeding and slow-moving wire cutting.
The principle of the EDM machine is similar to that of wire EDM, but since the electrodes used are formed electrodes processed by cnc or precision engraving machines, its surface is relatively large, so the high-frequency power supply and The current is completely different, so the maximum current of the EDM machine can reach about 50 amps. Since the electrodes for EDM machining are different, the surfaces he processes are generally in the shape of blind holes, or some fine engraving machines are used to process the remaining clean-cut surfaces that cannot be machined. Compared with wire cutting, there are advantages and disadvantages. What kind of shape we want to get, we must pre-process a completely identical electrode, commonly known as copper male. Of course, EDM can also machine through holes, but this method is generally not used because it is very labor-intensive. Wire EDM has the advantage that it can cut a narrow slit to cut off the workpiece, and the removed part can even be reused, but the principle of the EDM machine is to directly use electrodes for the remaining and unnecessary metals. removed, so it cannot be reused. And the volume of processing consumption is very large. Therefore, generally, CNC, engraving machine or milling machine is used for rough machining before EDM.
