    • A method for machining materials difficult to cut by EDM conventional processes and consisting in providing contamination of the machining or dielectric fluid used in the course of electrical discharge machining with particles of a metal or metallic alloy of low vaporization temperature selected, for example, from the group consisting of zinc, cadmium, tin, lead, antimony and bismuth. The contamination particles are obtained directly from a surface coating placed directly on the electrode tool or from an additional piece of metal or metallic alloy which is electro-eroded at the same time as a cut is effected by the electrode tool in an electrode workpiece, and the contaminated fluid is circulated in the machining zone between the electrodes, the contaminated fluid facilitating the triggering of the electrical discharges in the machining zone and providing an increase of the machining rate, or material removal rate.
    • 一种用于通过EDM常规方法加工难以切割的材料的方法,并且包括在放电加工过程中使用的机械加工或介电流体的污染物,其具有低蒸发温度的金属或金属合金的颗粒,所述金属或金属合金选自例如 由锌,镉,锡,铅,锑和铋组成的组。 污染颗粒直接从直接放置在电极工具上的表面涂层或从电极工具中的电极工具进行切割的同时被电腐蚀的附加金属或金属合金制成,以及 受污染的流体在电极之间的加工区域中循环,污染的流体有助于触发加工区域中的放电并提高加工速率或材料去除速率。
