电加工技术是本世纪四十年代逐步发展起来的新型加工方法。随着科学技术的飞速发展,高强度、高硬度、高韧性、耐高温等新型金属和非金属材料,以及高脆性磁性材料广泛应用在电子、宇航等工业上,某些细小精密、形状复杂工件的加工,用传统的机械加工方法已经难以胜任,于是促进了电加工技术的发展。当前,电加工是指电火花加工、电解加工、电解磨削、电子束加工、等离子体加工、激光加工和超声波加工等等。电火花加工电加工技术的应用是从电火花加工开始的。在电气线路的开关部位,常常可以看到一种蓝白色火花的放电现象,它能使
Electrical processing technology is a new processing method developed gradually in the 1940s. With the rapid development of science and technology, new types of metal and nonmetal materials such as high strength, high hardness, high toughness, high temperature resistance and high brittleness magnetic materials are widely used in industries such as electronics and aerospace. Some fine and complex workpieces with complex shapes Of the processing, with the traditional mechanical processing methods have been difficult to competent, thus promoting the development of electrical processing technology. Currently, EDM refers to EDM, electrolytic machining, electrolytic grinding, electron beam processing, plasma processing, laser processing and ultrasonic processing and so on. EDM EDM technology is the application of EDM from the beginning. In the electrical circuit switch parts, you can often see a blue-white spark discharge phenomenon, it can make
