Abstract

Le procédé de l'invention peut s'utiliser lors du traitement électrochimique de précision destiné à fabriquer des pièces de machines présentant des surfaces à configuration complexe. On fournit des impulsions anodiques réglables de courant ou de tension haute fréquence d'activation en paquets, qui sont synchronisées avec le moment du rapprochement maximal de l'électrode oscillante, de l'outil avec l'électrode - ébauche. Le traitement se fait avec de faibles entrefers de travail des électrodes. Pendant le traitement la vitesse d'alimentation de l'électrode / outil est augmentée graduellement jusqu'à ce qu'on assure des impulsions de tension décroissant de façon monotone ou des impulsions de tension croissant de façon monotone dans le paquet. On régule la vitesse d'alimentation de manière à maintenir le niveau obtenu des changements de chaque impulsion dans le paquet. La durée du paquet d'impulsions est limitée par leur nombre maximal assurant le caractère croissant de façon monotone de chaque impulsion dans le paquet. On régule la fréquence, la durée et l'amplitude de chaque impulsion dans le paquet. Le traitement se fait dans des électrolytes à base de solutions aqueuses à un composant de sels neutres. Le procédé permet d'augmenter la productivité, la précision et la qualité du traitement.
