Abstract

Un tour automatique ayant deux broches parallèles de travail (12a, 12b) présente sur une coulisse commune (14) trois coulisseaux (20a, 20b, 20c) portant des chariots longitudinaux différents (24a, 24b, 24c) les deux chariots extérieurs étant subordonnés chacun à une seule broche de travail, alors que le coulisseau central (20c) avec son chariot longitudinal (24a) et les outils qui y sont attachés peut être utilisé avec les deux broches de travail (12a, 12b). Pour entraîner le coulisseau central (20c), un arbre séparé d'entraînement (34c) est agencé dans un canal supplémentaire en forme de rainure de la coulisse en forme de barre de guidage. L'agencement du troisième coulisseau (20c) permet d'éviter des temps morts de l'une ou de l'autre broche de travail (12a, 12b) et de réduire la durée totale d'usinage.
