冲模电火花加工自从采用钢对钢工艺以来,无论生产率和质量都有了很大提高。但闸流管(包括电子管)式脉冲电源在生产过程中,当粗规准加工时,存在着电极损耗大的问题,特别是尖角位置,损耗严重,对于电机定转子复式模加工质量影响很大。据粗略统计,属于电极损耗大的模具约占15％左右。改用高低压脉冲加工后,电极损耗大的现象较好地解决了。
Die EDM since the use of steel on the steel process, both productivity and quality have greatly improved. However, in the production process of thyratrons (including electron tube) pulse power supplies, there is a problem of large electrode loss when the rough standard machining is carried out, especially the sharp corner position, and the loss is serious, and the influence on the processing quality of the stator of the stator and the rotor is very serious Big. According to rough statistics, a large electrode loss of about 15% of the mold. Switch to high and low voltage pulse processing, the electrode loss of a good solution to the problem.
