[0067] The working principle of this utility model is as follows: The first gripping robot 14 moves in the Z direction to grip the workpiece 5 to be processed on the blank table 3. Then, the first gripping robot 14 moves in the X direction to unload the workpiece 5 onto the workpiece rotary table 2. The workpiece rotary table 2 drives the workpiece 5 to rotate around the center. The internal turning tool 9, the external turning tool 10, and the grinding wheel assembly 13 perform internal turning, external turning, and end face grinding operations on the workpiece 5 by shifting in the X and Z directions, respectively. The second gripping robot 62 flips and grips the workpiece on the workpiece rotary table 2 that has completed one-end grinding. 5. Subsequently, the second gripping robot 62 flips and resets to flip the workpiece 5. Then, the first gripping robot 14 picks up the flipped workpiece 5 from the second gripping robot 62 and unloads it onto the workpiece rotary table 2 for grinding the other end face of the workpiece 5. After the workpiece 5 is ground, the first gripping robot 14 picks up the finished workpiece 5 and places it under the workpiece probe 34 so that the workpiece probe 34 can accurately measure the workpiece 5. Finally, the workpiece 5 is picked up and unloaded onto the finished product table 4, and the work steps are repeated.
