Combined processing machine tool

The invention relates to the field of numerical control machine tools, and discloses a combined machining machine tool which is characterized in that a double-gantry structure is arranged on a machine tool body, so that double machining stations are respectively formed below a tool spindle and a laser device assembly, and a workbench runs along an X axis and respectively reaches a laser machining station and a tool machining station according to machining requirements; milling machining and laser machining can be completed through one-time clamping, so that the clamping error caused by workpiece disassembly is reduced, and the machining precision and the machining efficiency are improved; in addition, the problem of transportation and fixation of sliding parts on the combined machining tool is solved, the spindle box and the tool spindle are ingeniously fixed to the workbench through the protection frame, the spindle box and the tool spindle are supported and fixed through the workbench, and the protection fr
