随着电子工业和汽车工业的飞速发展 ,对模具和零件加工的要求越来越高 ,期望高速化、高精度化、微细化。反之 ,又要求大幅度缩短加工周期和降低加工成本。面对这一挑战 ,日本三菱电火花线切割机床在高刚性、高精度机械结构、超高精度传动进给系统、高速无电解的脉冲电源及超精 With the rapid development of the electronics industry and the automotive industry, the requirements for the processing of molds and parts are getting higher and higher, and the speed, precision and miniaturization are expected to be high. On the contrary, it also requires a substantial reduction in processing cycles and reduce processing costs. Faced with this challenge, Japan’s Mitsubishi WEDM in high-rigidity, high-precision mechanical structure, ultra-precision drive feed system, high-speed electroless pulse power and ultra-fine
