In a method for removing material from a component (10, 10') that is connected as an anode, and wherein an electrode (12) that is connected as a cathode is guided to the component such that a gap (16) is formed, and wherein an electrolyte is introduced into the gap, a closed system is formed for the electrolyte by the formation of a duct. Said electrolyte is continuously guided from an inlet opening to an outlet opening of the duct. Forming the duct, e.g. by means of guide elements (18) that are mounted on the electrode (12), ensures that only those surface parts of the component (10) to be machined from which material is to be removed enter in contact with the electrode while the other surface parts do not enter in contact with the electrolyte. Since the electrolyte is continuously guided across said surface, used electrolyte is continuously discharged along with residual matter while fresh electrolyte is delivered such that the method can be carried out in a particularly trouble-free and expedient manner.
L'invention concerne un procédé d'enlèvement de matériau d'un élément (10,10') faisant fonction d'anode, auquel est reliée une électrode (12) en tant que cathode, de manière à former un interstice (16) dans lequel est introduit un électrolyte, la formation d'un canal permettant de créer un circuit fermé pour l'électrolyte. Cet électrolyte circule en permanence entre une ouverture d'entrée et une ouverture de sortie du canal. La formation du canal, par exemple par des éléments de guidage (18) fixés sur l'électrode (12), garantit que seules les parties de la surface de l'élément (10) à usiner dont du matériau doit être enlevé entrent en contact avec l'électrolyte sans que l'électrolyte ne touche les autres parties de la surface de l'élément. La circulation permanente de l'électrolyte sur ces surfaces permet d'évacuer en permanence de l'électrolyte usagé avec des résidus et d'amener de l'électrolyte pur, le procédé étant ainsi réalisé rapidement et sans dysfonctionnement.
