EDM mold processing, let precision become the norm!
Author:
EDM is a kind of metal processing technology using discharge phenomenon, through the action of high frequency pulse current, the electrode and the workpiece generate electric spark discharge, thus machining precision shape. This machining process can be carried out on hard materials, such as steel, aluminum, copper, etc., and can also be processed into very precise parts.
So, what is unique about EDM in mold processing? Let me reveal it for you!
- First, no direct contact is required.
EDM machining does not require direct contact with the workpiece, but is cut by electrical discharge between electrodes, so the possibility of mold surface damage by mechanical forces can be avoided. This is very important for molds that need to maintain high precision and finish.
- Second, the difficulty of processing is not limited by the hardness of the material.
EDM processing can handle most hard materials, whether steel, aluminum or copper, with ease. This can solve some of the traditional processing methods are difficult to deal with high hardness materials, improve the scope of application of mold processing.
- Third, improve the surface quality.
Since EDM processing does not need to touch the workpiece, it will not produce mechanical cutting marks, which can greatly improve the quality of the die surface and reduce the polishing work in the later period.
- Fourth, the processing accuracy can reach the micron level.
The discharge process of EDM processing can be accurate to the micron level, and very precise mold processing can be achieved to meet the needs of high precision. For some special shapes or complex structures of the mold, EDM is a very effective processing method.
The above is the impact of EDM on the surface integrity of the mold, so that we have a deeper understanding of the mold processing. Moreover, I believe that there will be more breakthroughs and innovations in EDM processing technology in the near future!
