the embodiment provides a car and roll compound digit control machine tool, utilizes turret mechanism to go on unloading to the work piece, and after turret mechanism placed the work piece on work piece clamping mechanism, work piece clamping mechanism drove the work piece and rotates, and turret mechanism processes the work piece, and hobbing cutter mechanism also can process the work piece. Therefore, multiple times of processing can be carried out on the same machine tool, workpieces do not need to be mounted and dismounted for multiple times, and the effects of improving the working efficiency and the processing precision are achieved. Multiple machining processes such as turning, gear hobbing, milling, drilling and the like are combined to one machine tool, one-time clamping can be realized, multi-process machining is completed, the machining precision is improved, and the auxiliary time is shortened.

The foregoing is illustrative of embodiments provided in connection with the detailed description and is not intended to limit the disclosure to the particular forms set forth herein. Similar to the structure of the method, or several technical deductions or substitutions made on the premise of the conception of the present application, should be regarded as the protection scope of the present application.
