Abstract
Procédé de réalisation en une seule pièce, avec étincelage électrique, d'un dispositif de tuyères multiples pour des lasers à gaz et chimiques. Dans un bloc métallique 13 forgé de texture serrée, on creuse à la fraise 14 jusqu au dégrossissage les canaux d'écoulement, puis on amène ceux-ci à la précision par étincelage électrique, on polît leurs surfaces jusqu'à l'extrême précision en un ou plusieurs finissages par électro-érosion et on perce le col 15 des tuyères, en électro-érosion de précision, à un calibre inférieur à la cote finale. L'invention fournit aux lasers à gaz ou chimiques des éléments précis et fiables.
