Machine tool having a conveying device for leading away chips

A machine tool for machining a workpiece, said workpiece being clamped in a working space of the machine tool, the machine tool comprising:

• a machine bed, which has a chip collection region having at least one conveying channel open on a working space side for collecting chips that drop during the machining of the workpiece;
• and
• a conveying device for leading away chips that have dropped into the chip collection region in the at least one conveying channel, the conveying device including:
• a stationary supporting shaft, which extends in the at least one conveying channel in a longitudinal direction of the at least one conveying channel;
• a spiral element being rotatably supported on the stationary supporting shaft;
• and
• a drive for driving a rotational motion of the spiral element about the stationary supporting shaft, such that the stationary supporting shaft remains stationary when the spiral element rotates.
