线切割加工电极丝的使用寿命,大家是比较关心的。为此,有些单位在机床、电气(包括电源)以及操作等方面作了不少工作,效果显著。此外,我厂在生产实践中,认为电极丝的材料也很重要。我们发现钨钼合金电极丝(各50％)的使用寿命较纯钼丝的为长,且相应的生产率也有所提高。这大概是与材料的物理性能有关,特将其表列如下: Wire cutting wire electrode life, we are more concerned about. For this reason, some units have done a lot of work in machine tools, electrical (including power supply) and operation, with remarkable results. In addition, I plant in the production practice, that the electrode wire material is also very important. We found that tungsten-molybdenum alloy wire (each 50%) of the service life of pure molybdenum wire is longer, and the corresponding productivity has also increased. This is probably related to the physical properties of the material, especially as follows:
