Machine tool for e.g. processing titanium workpieces, for manufacturing airplane, has counterweight device coupled with processing unit such that weight force actuated on processing unit is compensated by rotational torque of motor

摘要

The tool (1) has a processing unit (33) processing a workpiece and moved along a vertical direction relative to a machine frame (3). An electromechanical counterweight device (44) partially inputs a weight force (G) that is actuated on the processing unit along the vertical direction, where the counterweight device comprises an electrical counterweight motor (45). The counterweight device is coupled with the processing unit such that the weight force actuated on the processing unit is partially compensated by a rotational torque of the counterweight motor.
