<p>The tool-holding spindle (3) is mounted in rotation in a stator (13) via bearings (6, 7, 8, 9) with a very high static rigidity. The rotor (21) of the electric motor is mounted in another stator (22) via flexible bearings (25, 26), the two spindle and motor stators (13 and 22) being integrally connected and arranged coaxially aligned. The tool-holding spindle (3) and the rotor (21) of the motor are connected together by a coupling (32, 33) which has a high circumferential rigidity but can flex. <IMAGE></p> |
