ABSTRACT:
In order to improve a lathe, in particular, a multiple-spindle lathe, comprising at least one workpiece spindle arranged on a machine frame and rotatable about a spindle axis, this workpiece spindle projecting with its front end into an operating area, and a tool slide with a longitudinal slide element guided for displacement in Z-direction parallel to the spindle axis in a longitudinal guide means located outside the operating area and arranged on a slide stand of the machine frame and with a cross slide arranged in the operating area and displaceable in X-direction transversely to the spindle axis in relation to the longitudinal slide element, this cross slide being guided on a cross slide guide means arranged at a front end of the longitudinal slide element and movable by means of a cross feed gear, such that the tool slide as a whole is constructed in as space-saving a manner as possible and, in particular, requires little space in the operating area in order to create the possibility of using several tool slides on one workpiece spindle, it is suggested that the longitudinal slide element bear a cross feed motor for the cross feed gear in an area located outside the operating area and that this cross feed motor drive the cross feed gear by means of a rotary transmission element extending in a longitudinal direction of the longitudinal slide element.
