By using the double rack and four motor drive method, plus the drive of the servo motors 10 and the reducer 12 and gears 13, better positioning accuracy can be obtained through the cooperation of the CNC system in the machine tool body 1 to meet more processing needs.

[0020] refer to Figure 1 A base 2 is fixedly connected to the bottom end of the machine tool body 1, and the base 2 covers the bottom end of the machine tool body 1. A first connecting block 3 is fixedly connected to the outside of the base 2, and the top end of the first connecting block 3 is fixedly connected to the bottom end of the machine tool body 1. Due to the presence of the base 2, the bottom end of the machine tool body 1 can be effectively supported, which can effectively improve the stability of the machine tool body 1 during operation. The first connecting block 3 can make a secondary connection between the connection point between the base 2 and the machine tool body 1, so as to improve the installation stability of the base 2.

[0021] refer to Figure 1 The top of the machine tool body 1 is provided with a slide groove 4 that matches the first worktable 5 and the second worktable 8. The first worktable 5 and the second worktable 8 are slidably connected to the top of the machine tool body 1 through the slide groove 4.
