往复走丝线切割机床电极丝加工质量因素的分析

摘要

往复走丝电火花线切割加工参数的合理选用对零件加工质量有着至关重要的作用。在对往复走丝线切割机床DK7732多次加工实践的基础上，分析了在线切割加工中电极丝的材料、直径、走丝速度、张紧力、电参数、工作液、垂直度等主要因素对加工质量的影响，从而为往复走丝线切割机床加工参数的选择提供参考。%The rational selection of processing parameters of reciprocating wire electrical discharge machining is crucial to the quality of parts.Based on a large amount of machining practice on DK7732 machine tool,the impacts of the main factors,such as the wire electrode material,diameter,wire speed,tension,electrical parameters,working fluid,verticality etc,on processing quality were analyzed.It provides some reference for processing parameters selection of reciprocating-feed WEDM.
