Abstract
An automatic lathe having two workpiece spindles each provided with a workpiece clamping device and arranged with coaxial spindle axes. At least one of the workpiece spindles is arranged on a slide guided for displacement in the direction of the spindle axis and displaceable in the direction of the spindle axis by a drive element and a coupling device between the drive element and the slide. In order to compensate for axial movement component of the clamping device during clamping, the coupling device is designed such that in a first condition thereof, the slide is freely displaceable relative to the drive element in the direction of the spindle axis and opposite to the axial movement component of the clamping device. In a second condition of the coupling device, the slide is not displaceable relative to the drive element in the direction of the spindle axis.
