Abstract
Procedimento per la lavorazione elettrochimica di pezzi metallici lastriformi il quale si caratterizza per il fatto che il pezzo metallico viene dapprima ricoperto almeno su un lato con uno strato di materiale elettricamente isolante che lascia scoperte le zone da rimuovere, quindi immesso in un bagno elettrolitico costituito da una soluzione acquosa di NaC1 e contrapposto ad una piastra metallica avente dimensioni sostanzialmente corrispondenti a quelle di detto pezzo, detti pezzo e piastra essendo collegabili con i poli positivo e rispettivamente negativo di una tensione di alimentazione continua tale da determinare l'asportazione di metallo da dette zone scoperte.Process for the electrochemical processing of sheet metal parts which is characterized by the fact that the metal piece is first covered on at least one side with a layer of electrically insulating material which leaves the areas to be removed uncovered, then placed in an electrolytic bath consisting of an aqueous solution of NaCl and opposed to a metal plate having dimensions substantially corresponding to those of said piece, said piece and plate being connectable with the positive and respectively negative poles of a continuous supply voltage such as to determine the removal of metal from said uncovered areas.
