Abstract

Cette invention concerne une fixation amovible destinée à assujettir des éléments devant être usinés. Une forme de réalisation préférée de cette fixation amovible permet de préférence d'usiner complètement un élément à usiner sur cinq côtés dans un support ou mandrin de l'élément à usiner sans qu'il soit nécessaire de le sortir ou de l'enlever de la fixation, ceci éliminant par conséquent ce qu'on appelle communément les charges 'A' et 'B' qui sont deux supports séparés d'un élément à usiner qu'on utilise en raison de l'inaptitude des pièces de centrage classiques à présenter le haut et le bas de l'élément à la broche de la machine-outil dans la charge 'A' uniquement.
