电火花线切割技术的发展与加工电源的进步是密切相关的。早期的RC电源放电重复频率低、放电能量小,加工生产率低。由于是少数人关着门搞试验,长期停滞不前,使电火花线切割加工局限在加工精小冲模和零件的范围内。然而经过无产阶级文化大革命的战斗洗礼,广大工人群众占领上层建筑领域,实行科研与生产三结合开门办科研,大搞线切割工艺试验的群众 The development of WEDM technology is closely related to the progress of power supply. Early RC power discharge low repetition frequency, discharge energy is small, low processing productivity. Because it is a few people engaged in experiments with closed doors, long-term stagnation, so that EDM is limited to the processing of small dies and parts range. However, after the baptism of the proletarian cultural revolution, the masses of workers occupy the superstructure and practiced the combination of scientific research and production to run scientific research and popularize wire cutting technology
