The first support plate 46 mounted on the first turret slide 20 is driven by the first turret 1 vertical feed servo motor 42 to move the first turret 16 on the first support plate 46 up and down on the first turret slide 20. So that the turning tool I47 can process the workpiece 13 under the action of the tool turret-rotating servo motor 19. Similarly, the second support plate 49 mounted on the second sliding table 26 of the turret drives the second upper and lower feed screw 28 of the second turret by the second upper and lower feed servo motor 53 of the second turret, so that the second turret 30 on the second support plate 49 moves up and down on the second sliding table 26 of the turret, and the second turning tool 48 machines the workpiece 13 under the action of the second rotary servo motor 27 of the turret.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents or improvements made within the spirit and principle of the present invention should be included in the scope of the present invention.
