Abstract

L'invention concerne les appareils de retrait électrolytique de matière. Elle se rapporte à un appareil dans lequel les électrodes sont déplacées par des vérins alimentés par des pompes hydrauliques commandées elles-mêmes par un dispositif d'entraînement. Toutes les électrodes s'arrêtent à des positions intermédiaires et repartent simultanément vers une autre position. La pompe alimentant le vérin a une capacité bien inférieure à celle du vérin. Application à l'usinage chimique des ailettes de turbines.
