The present invention achieves improvement of an adjustment structure of a turning spindle in the vertical direction and the horizontal direction. A turning spindle unitincludes a turning spindle base push-pull blockwhich adjusts a turning spindle basefixed onto a bedin the horizontal direction. The turning spindle baseincludes a turning spindle push-pull blockto push and pull a turning spindle. A mounting seatinclines at an angle to the horizontal plane.

Turning spindle unit of multi-tasking machine

The present invention aims at improving the efficiency of tool management by improving the arrangement of a tool magazine in a composite working lathe. The composite working latheincludes a spindle stock and a tool spindle disposed on a bed, and a covercovering the surrounding area thereof. A doorallowing access to a machining portion is provided on a front side F of the machine, and the machining portion can be visually observed through a window. A tool magazine unitis disposed in front of the spindle stock of the machine. A doorand a windoware provided on the cover of the tool magazine unit, allowing operators to observe the tool stored in the magazine through windowsand. The present composite working lathe enables to improve the efficiency of tool management, such as the confirmation of the tool used in the subsequent step or the removal of chips on the used tool.

Composite working lathe

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

The invention provides a device for automatically carrying in and out a workpiece cooperating with a tool spindle stock of a composite working lathe. The composite working lathe comprises a main spindle, a workpiece handling deviceand a tool spindle stockthat rotates around a B axis. A workpiece carry-in/out devicecomprises a frameincluding a material carry-in handand a finished product tray, and a cylinderfor moving the frame back and forth. A doorof a coveris opened to carry in a material Band carry out a finished product P.
