在毛主席无产阶级革命路线指引下,我们遵照“鞍钢宪法”的精神,走三结合的道路,与四一○厂、一○○厂对多小孔火焰筒发散壁加工进行了研究,研制了一台DMC—2型电脉冲机床和一台JMD—2型两回路晶体管复合脉冲电源。二者配合使用,一次可加工出2100多个直径0.5毫米的小孔,加工时间不超过半小时。根据试验,该设备还可加工涡轮导向叶片、涡轮叶片上的气膜冷却孔、窄槽和型孔,也可加工中小型精锻模、
Under the guidance of Chairman Mao’s proletarian revolutionary line, in accordance with the spirit of the “Anshan Iron and Steel Constitution,” we followed the path of “three combinations.” We conducted research on the fabrication of multi-orifice flame tube divergent walls at 410 or 1100 and developed A DMC-2 electric pulse machine and a JMD-2 two-circuit transistor compound pulse power supply. With the use of the two, can be processed out of more than 2,100 0.5 mm diameter holes, processing time does not exceed half an hour. According to the test, the device can also process turbine guide vanes, film cooling holes on the turbine blades, narrow slots and holes, but also small and medium precision forging dies,
