此设备在72年5月进厂安装。原是闸流管控制电压,由于不好用,到外地学习经验后,改成单闸流管,可是经过几个月的加工试验,一直未掌握住加工产品的稳定性与电压值的关系。因此加工出来的冲模质量不好,冲子腐蚀量大,效率低,经常出废品。通过学习优选法之后,和我们电火花加工的实际情况相结合。认为电压是电火花加 This equipment was installed in May, 72 in the factory. The original thyristor control voltage, due to poor use, to learn the experience of the field, into a single thyratron, but after several months of processing tests, has not grasp the stability of processed products and voltage values. Therefore, the quality of the processed die is not good, the punch corrosion, low efficiency, often out of waste. After learning the optimization method, combined with the actual situation of our EDM. Think voltage is EDM
