The development course of electric spark machine tools

Electric spark machine tools since the 1950 s, was born in China, through a long and rapid development, technology is becoming more and more advanced, more and more widely used, has now occupies a very important position in the mould industry in China, every year there are more than 10000 new edm machine tool into the mould manufacturing field. Type in the mold surface machining, electric spark machine tool whilst under the severe challenges of high speed engraving and milling machine, but because of its unique properties and technology advances, electric spark machine tools in the future will still play its unique role in the mold industry, and get further development. China's first electric spark machine tools was born in 1954. In 1958 successfully developed DM5540 type electrical machine has the advantages of high efficiency, small electrode loss, starting a electric machine to mould processing period. “ Steel type steel & throughout; Electric processing technology research successfully solved the electrode and the match problem of punch, this makes the electric machine in the mold ( Especially the stamping die) A further popularization and application in the processing. In 1965, the transistor pulse power D6140 electric spark forming machine to broaden the application of electric machining in cavity die. Thyristor power supply and the transistor power electric machine tools, get greater development in the 1970 s, and constantly improve the translation of their head, the combination of the cavity die edm translation technology becoming mature, promote the new development of edm of cavity die. Wire-cut edm machine rapid development from the 60 s: the 1964 China photoelectric tracking wire-cut edm machine is developed and fast walking wire edm wedm. In 1969, quickly stepped wire CNC wire-cut edm machine. With the development of numerical control technology, electric spark machine tool has the new breakthrough in the 1980 s, have some of the high performance CNC edm machine tools.
