Abstract
A work unit for automatic machine tools is provided with a spindle that moves in translation and rotates with respect to a work axis. The spindle is housed within a sleeve that is slidable along the work axis, with the spindle being rotatable within. Rotation of the spindle is controlled by a drive unit mounted directly on the spindle and arranged inside the sleeve, which eliminates the need for a separate transmission mechanism and thereby results in a simplified construction of the work unit and an increase in performance.
