TURRET FOR TOOL MACHINE

摘要

A turret for tool machine includes:
at least a turret body supported by the tool machine;at least a rotating drum supported by the turret body and supporting at least two tool holders upon which are mounted at least two rotating tools the rotating drum being mounted externally rotating around the turret body;at least an electrical spindle positioned in a recess inside the turret body; the electrical spindle extending itself around a vertical axis;the electrical spindle including a motor, a rotating shaft for the transmission of the movement associated to the motor and an engagement portion suitable for coupling to the tool holder;each tool holder extending itself along a vertical axis;the rotating drum being rotatably mounted around the turret body so as to rotate for aligning each tool holder with the engagement portion.
