The advantages of wire EDM

With the advancement of science and technology, wire EDM processing technology has developed into an important processing technology in the machining industry, with high processing accuracy and relatively few restricted conditions. The precision of the parts processed by wire EDM is beyond the reach of general machining technology. Moreover, the processing range is relatively wide, basically any metal conductive material can be processed, and it is not limited by the hardness of the material. Wire EDM does not produce the objective force of other processes during processing. The driving force required by the spindles of all machine tools is relatively small. In this case, only a relatively small motor is required to operate normally, which is correspondingly Improve the processing accuracy of the product. Wire EDM is becoming more and more popular because of its advantages: 1. Wire EDM electrodes use 0.03-0.35mm metal wire, so there is no need to process special electrodes, which saves money. The time to process the electrode is eliminated, and the production efficiency is greatly improved. 2. The processing range is wide. The products processed by EDM are not affected by the hardness of the material, and conductive materials that cannot be processed by other processes can be processed, and the materials can be processed by heat treatment first, which avoids the deformation problem caused by the heat treatment of the product. However, the material must be conductive before it can be processed by wire EDM. 3. Low requirements on product shape. In addition to the influence of metal wires and gaps at the inner corners of the product, wire EDM can basically be used for products of any shape. 4. Save materials. Since the metal wire is only about 0.3mm, the knife edge of the product after processing is very small, which greatly improves the material utilization rate and reduces the material cost. This feature makes wire EDM processing precious metals have advantages that other processing can't match. 5. The fast-moving wire can recycle the metal wire, and the loss of consumables is very small. Although the slow-moving wire cannot be recycled, it can process micron-level products with precision. 6. High security. The working fluid of wire cutting is non-flammable liquid, which can realize unmanned operation. Previous post: Key technologies for powder fuel ramjet engines to be solved urgently
