摘要:
Die Erfindung betrifft eine Elektrode zur elektrochemischen Bearbeitung eines Werkstücks, wobei die Elektrode als kathodisch gepolte Werkzeugelektrode ausgebildet ist und zumindest in einem Arbeitsbereich eine Geometrie aufweist, die der abzutragenden Geometrie auf dem Werkstück entspricht und Wegsamkeiten in der Elektrode zum Durchfluss und Austritt eines Elektrolyten an der Elektrodenoberfläche zumindest im Bereich des Arbeitsbereichs aufweist. Die Wegsamkeiten werden dabei durch eine poröse Ausbildung der Elektrode und/oder durch künstlich geschaffene Öffnungen in der Elektrode beziehungsweise der Elektrodenoberfläche ausgebildet. Die Porositätsverteilung und/oder die Anzahl, die Anordnung und die Ausgestaltung der Öffnungen derart gewählt ist, dass ein gleichmäßiger E-lektrolytfluss und/oder Elektrolytaustausch an der Elektrodenoberfläche zumindest in dem Arbeitsbereich der Elektrode gewährleistet ist. Die Erfindung betrifft weiterhin Verfahren zur elektrochemischen Bearbeitung eines Werkstücks mit einer Elektrode und Verwendungen der erfindungsgemäßen Elektrode.

摘要:
Disclosed is a method for removing material from a component (10, 10') that is connected as an anode. In said method, an electrode (12) that is connected as a cathode is guided to the component such that a gap (16) is formed, an electrolyte is introduced into the gap, and a closed system is formed for the electrolyte by forming a duct. The electrolyte is continuously conducted from an inlet to an outlet of the duct. Forming the duct, e.g. by means of conducting 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 conducted 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.
