La présente invention concerne le domaine de l’usinage par enlèvement de matière. L’invention a ainsi pour objet une machine d’usinage et, plus particulièrement, une machine de perçage ou de fraisage. La machine à la particularité d’intégrer deux moteurs électriques destinés à contrôler les mouvements d’avance et de rotation d’un outil, tout en permettant une action d’assistance vibratoire, particulièrement utile pour le perçage de matériaux difficiles à usiner. The present invention relates to the field of machining of materials by chip removal. The invention presents a special machine tool and, more particularly, a drilling or milling machine. The machine has the particularity of incorporating two electric motors for controlling the feed and rotation motions of a tool, while allowing a vibration assistance optional motion, particularly useful for drilling hard to machine materials .
