Abstract
Des disques (1) pour pompes turbomoléculaires, sont pourvus d'une couronne d'aube aménagées par la formation de fentes au moyen d'une scie en pot (2). On opère sur plusieurs disques à la fois montés sur un montage unique (8). La section transversale des aubes formées peut etre constante ou non constante selon le type du mouvement relatif des axes (6, 9) de la scie et du montage (8).
