[0002] CNC machine tool is the abbreviation of digital control machine tool. It is an automated machine tool equipped with a program control system. The control system can logically process programs specified by control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the CNC device through information carriers. Generally, as the worktable of the machine tool, there are worktables that do not perform rotational motion and rotary worktables that perform rotational motion. The rotary worktable has a device for performing rotational motion.

[0003] When the rotary table drives the workpiece to rotate to a certain angle during use, it is necessary to stop operating the table. However, the worktable is usually fixed by the meshing of worm gears, which has a poor fixing effect and is difficult to ensure the stability of the workpiece during processing. When the table slides, processing will be inconvenient. Therefore, it is necessary to design and modify the rotary table to solve the problem of sliding after it moves. Utility Model Content
