摘要
改进了冷拔钢管所需硬质合金模具的加工工艺,采用电化学腐蚀法和机械法相结合,既节省加工时间,又减少了投资费用,并实现了电蚀机床一机多用。
The improvement on processing of carbide dies for steel pipe cold-drawing involves a combination of electrochemical erosion method with machining, which leads to reduction of both machining time and investment as well as the multi-use of the electroerosion machine tool.
