Abstract

Broche haute vitesse à assistance vibratoire mécanique forcée Broche (1) pour machine-outil, comportant Un carter (10), un arbre (20) d’entraînement d’un outil de coupe, monté rotatif à l’intérieur du carter avec une possibilité de déplacement axial relativement au carter, une unique bille (200), s’interposant axialement entre une bague de roulement (202) fixe relativement au carter et une bague de roulement (201) mobile avec l’arbre, l’une de ces bagues de roulement définissant une surface de roulement inclinée (231) non perpendiculaire à l’axe de rotation de l’arbre, de telle sorte que la rotation de la bille génère une oscillation axiale de l’arbre. Figure pour l’abrégé : Fig. 2
