Abstract

Устройство для электрохимической обработки металлической заготовки, включающее в себя несколько электродов, имеющих направленную к заготовке моделирующую поверхность, которые могут линейно перемещаться из исходного положения в конечное положение с помощью соответствующих линейных приводных узлов относительно заготовки, при этом предусмотрены по меньшей мере три электрода (4, 5, 6, 7), которые расположены со сдвигом по периметру заготовки (2) и своими моделирующими поверхностями (13, 14, 15, 16) во время всего перемещения перестановки из исходного в конечное положение, касаясь друг друга, охватывают друг друга отдельными участками и своими моделирующими поверхностями (13, 14, 15, 16) ограничивают канал для текучей среды (12), проходящий закрытым образом вокруг по периметру заготовки (2).
