基于环形电极的曲孔加工方法

Process of arc hole by hollow electrode

探讨利用直柄和弧柄环形电极电火花加工曲孔的方法,可加工任意横截面的曲孔,通过加工实例,讨论其加工原理,分析了特别影响环形电极曲孔加工的工艺因素,包括电极形式、环形部分制作、芯料支撑方式、工作液方式和加工状态等,并就其加工特点进行了总结。

The process of machining hole with arc axis by hollow electrode on EDM is developed, in which the hollow electrode with a straight or arc holder adapts to get the arc holes with any cross - section. Basing on a real case, the processing theory is discussed, and the factors in the process, such as electrode form, hollow part making, core supporting structure, flowing way of the dielectric fluid, are analyzed.
