在模具电火花加工中实现中精加工,以较低的电极损耗而达到较高的生产率是多年来所研究的一个课题。因为中精加工低损耗,对于保证加工精度,提高模具质量,扩大电加工应用范围等方面具有重要意义。一机部苏州电加工机床研究所、上海市机械制造工艺研究所和上海星火模具厂的工程技术人员最近合作研制成功了“DS-1晶体管脉冲电源”和“DS-2可控硅脉冲电源”,这种电源通过生产验证已达到了中精加工电极少无损耗,具有国内先进水平。其鉴定实测的工艺指标是:加工表面光洁度为(?)5时,DS-1的电极损
In the mold EDM to achieve finishing, with lower electrode loss and achieve higher productivity is a subject studied over the years. Because the finishing low loss, to ensure the processing accuracy, improve the quality of the mold, expanding the scope of application of electrical processing is of great significance. One machine Suzhou Electrical Processing Machine Tool Institute, Shanghai Institute of Machinery Manufacturing Technology and Shanghai Spark Mold Factory engineering and technical personnel recently successfully developed a “DS-1 transistor pulse power supply” and “DS-2 SCR pulse power supply” , This power supply has passed the production verification has reached the finishing electrode less no loss, with the domestic advanced level. The identification of the measured process indicators are: processing surface finish (?) 5, DS-1 electrode loss
