高速走丝电火花线切割加工断丝故障分析及预防

Causes and Prevention of Wire Rupture in High-Speed WEDM Process

针对高速走丝线切割机常见的断丝现象,详细分析了电极丝易断的六大因素:电极丝的因素、送丝机构的因素、工件的因素、电参数的因素、工作液的因素、操作使用的因素等,提出了相应的预防方法,对改善工件表面质量和精度,提高加工效率有一定的借鉴作用.

The causes of filament break in high speed wire cutting machine were analyzed in details, such as the factors of electrode filament, the status of filament guiding mechanism, the causes of work pieces, the reason of electrical parameter and the anomaly of treatment fluid and operation. Prevention methods were put forward, which are significant to increase of the surface quality and accuracy of the work pieces and to improve the productivity.
