电火花线切割机断丝原因的研究

WEDM cause of broken wires

以DK7725型电火花线切割机为样本,对其在使用中的断丝原因进行了分析,并提出了相应的解决方法。针对线切割机在使用中出现的钼丝与导电块间的放电现象,分析了其影响,提出了自己的解决方法,并对提出的方法进行了论证,较好地解决了DK7725型线切割机在使用中的断丝现象。

In this paper,as a sample of WEDM DK7725,its use in the broken wire is analyzed and the corresponding solution method is brought out.In the light of EDM arising from the use of molybdenum in the wire and the discharge between the conductive block phenomenon,analyze its impact,put forwards their own solutions,and the proposed method were demonstrated,which can solve the DK7725 EDM broken wire in the use of the phenomenon.
