我厂原生产的 D6140A 高频脉冲电蚀加工机床,在进行型腔模加工时,通常采用紫铜或石墨电极材料,因其电极损耗小,加工稳定,生产率高,在进行冷冲模加工时,也可采用上述电极材料,加工性能亦稳定良好,但由于紫铜与石墨电极材料价格贵,来源不易,机加工困难,所以还经常需要使用铁素电极材料,如铸铁和钢,其中铸铁材料来源容易,成本低廉,而钢电极还可以兼作冲头,但它们的电蚀加工稳定性差,生产率较低,特别是 Cr12等合金钢的效率更低。为了扩大我厂生产的 D6140A 型电蚀加工机床的
The D6140A high-frequency pulsed electro-erosion machining machine originally produced by our factory usually adopts the copper or graphite electrode material when processing cavity molds. Because of its small electrode loss, stable processing and high productivity, when processing cold die, The above electrode materials can be used, and the processing performance is also stable. However, since the copper and graphite electrode materials are expensive, difficult to source and difficult to machine, iron electrode materials such as cast iron and steel are often used, Low cost, but the steel electrode can also double as a punch, but their electro-erosion machining stability is poor, low productivity, especially alloy steel such as Cr12 less efficient. In order to expand the factory production D6140A electric erosion machining machine
