线切割是电火花加工的一种,它的出现比穿孔成型加工晚十余年。19(?)8年苏联最早进行了电火花线切割实验,用来加工诸如慢波结构、阳极块等某些电真空器件,1960年首次在苏联国内展出样机。六十年代初,出现靠模仿形线切割机床,开始应用于模具加工,随后,相继出现光电仿形和数字控制线切割机床。西方国家的线切割机床最早是在 Wire EDM is a kind of EDM, its emergence than the piercing forming processing more than ten years later. 19 (?) 8 years The Soviet Union was the first WEDM experiment, used to process such as the slow wave structure, anode blocks and some other electrical vacuum devices, the first demonstration in 1960 in the Soviet Union prototype. The early 1960s, appeared by imitation shaped wire cutting machine, began to be used in mold processing, followed by the emergence of photoelectric and digital control of wire cutting machine. Western countries, the first line cutting machine is
