IPC: B23H09/10
CPC classification number: B23H9/10
Abstract: A multiple piece electrode for use with an electrical discharge machining device (EDM) includes at least one tooth. The electrode also includes a movable, elongated rod positioned inside each tooth. The movable rod may be secured to the tooth by several means such as a clamp mechanism, an epoxy, or by a securing mechanism attached to the processing equipment. When the electrode is advanced longitudinally into the workpiece, the rod forms a deep, small diameter hole and the tooth forms an enlarged opening at one end of the hole. The rod may be rotated to enhance hole depth capabilities. Additionally, the rod may be hollow, thus allowing a dielectric fluid to pass through the rod.
Abstract translation: 用于放电加工装置（EDM）的多片电极包括至少一个齿。 电极还包括位于每个牙齿内的可移动的细长杆。 可移动杆可以通过诸如夹紧机构，环氧树脂或通过附接到处理设备的固定机构的几种手段固定到齿上。 当电极纵向前进到工件时，杆形成一个深的，小直径的孔，并且齿在孔的一端形成一个扩大的开口。 杆可以旋转以增强孔深度能力。 此外，杆可以是中空的，从而允许介电流体穿过杆。
