Rotating milling assembly for machine tools and machining systems and method for operating such an assembly

摘要

The head has an interior rotor-torque motor with a rotor (14) that is directly supported at a tool spindle housing (2) by an intermediate ring (15). A stator (13) of the interior rotor-torque motor is supported at a main housing of a rotating milling device. A separate drive motor (12) is arranged parallel to a B-axis (B) of a tool spindle (3), is supported at the main housing and stays in effective connection with a drive shaft (7) of the spindle by a shifted gear. A liquid cooling unit is attached to the rotating milling device and comprises two tempering circuits (T1, T2). An independent claim is also included for a method for operating a drive head for a rotating milling-machining center.
