Abstract
The invention provides a composite working lathe capable of improving the efficiency of workpiece machining area by arranging a workpiece handling device below a spindle of the composite working lathe. The composite working lathecomprises a spindleand a tool spindleon a bed. A workpiece handling devicearranged below the spindlecan be moved along a W axis parallel to the axis line Cof the spindle. The workpiece handling devicehas a workpiece handling headthat pivots in the direction of arrow F around an axis line C, and grips the workpiece Kvia a gripper. The axis line Cis an axis perpendicular to the vertical plane including the axis line Cof the spindle, and the workpiece handling headis raised for 90 degrees when the gripperreceives the workpiece Kfrom the spindle. The angular position of the workpiece handling headis allocated and the workpiece Kis machined via a tool Ton the tool spindle
