摘要
研究了电火花线切割加工工作液成分和性质对加工的影响。通过改变电解质添加量,研究电火花线切割加工工作液性质对放电间隙伏安特性和电极丝损耗的影响,并对其作用机理进行探索。实验证明:电解质的添加改变了工作液的电导率,从而引起放电间隙伏安特性变化,提高了加工效率,同时增加了电解作用,大大降低了电极丝损耗。
The impact of wire cut cooling fluid composition and nature on processing has been studied. By changing the added amount of electrolyte,the effect of wire cut cooling fluid on discharge gap current voltage characteristics and electrode wire wear has been discussed,and its mechanism has been explored.Results show：with the increase in electrolyte,the conductivity of wire cut cooling fluid increase, which led to changes in discharge gap voltage characteristics,improve processing efficiency, while increasing the electrolysis to significantly reduce the electrode wire wear.
