电火花这门加工技术虽已较普遍应用,但随着生产发展的需要,对产品质量提出了较高的要求,特别是对一些特殊材料零件的加工以及对加工精度要求较高的零件,或者加工技术较难,利用现有的机械磨削方法已不能进行加工。为此,电火花加工技术应用范围就逐步扩大。近年来生产实践证明了这一点。所以电火花加工技术需要发展。为高难度的加工技术开辟道路。 Although EDM has been widely used in processing technology, with the development of production needs, the product quality put forward higher requirements, especially for the processing of some special materials and parts of the machining accuracy of the higher parts, or Processing technology is more difficult, the use of existing mechanical grinding methods can no longer be processed. To this end, EDM technology gradually expanded the scope of application. Production practice in recent years proved this point. Therefore, EDM technology needs to be developed. Pave the way for tough machining techniques.
