Abstract

L'invention concerne un appareil pour former électromagnétiquement une pièce à usiner, dans lequel l'appareil a un ensemble de formage et une source de courant. L'ensemble de formage comprend une unité de formage ayant une pluralité de cavités de formage, agencées en série, adaptées pour recevoir une pièce à usiner. Un espace médian s'étend à travers l'unité de formage en recoupant chacune des cavités de formage et en se terminant au niveau d'une des cavités de formage. La résistance et l'inductance dans les cavités de formage sont plus grandes que celles des connexions entre chaque cavité de formage.
