Abstract

Las unidades de EDM (100) se montan sobre una superficie de maquinado (1) y sub-electrodos giratorios de descarga (201) contra la superficie (1); los sub-electrodos (201) también pueden revolucionar alrededor de otro eje compartido al mismo que descarga. La rotación y revolución se puede lograr con engranajes planetarios (205) fijos con los sub-electrodos (201) y se entrelazan con un engranaje solar estacionario (204). Varios sub-electrodos (201) se pueden utilizar en una sola unidad (100); el movimiento hacia abajo de los sub-electrodos (201) desde un vástago central en el montaje permite maquinar varios centímetros de la superficie; las unidades (100) se pueden utilizar en un reactor durante un periodo de mantenimiento para maquinar un orificio para reemplazar una cubierta de pozo de acceso submarino en el reactor inundado; los diversos movimientos giratorios y el movimiento vertical pueden ser controlados de manera independiente con motores separados (160,170) en la unidad; la energía y los controles se pueden proporcionar de manera remota a través de una conexión submarina.
