The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0030] Example 1: Reference Figures 1 to 7, which is the first embodiment of the utility model. This embodiment provides a CNC lathe with a positioning and fixing function, which can solve the problem that most CNC lathes on the market currently have the problem that when positioning and fixing a cylindrical tool, the cylindrical product is easily shaken during cutting, thereby affecting the cutting effect of the cylindrical tool. The invention comprises a base 1, a shell body 101 is installed on the top of the base 1, a sealing door panel 102 is hinged on the side wall of one side of the shell body 101, a mounting seat 103 is installed at the bottom end inside the shell body 101, and a support plate 104 is installed on the top of the mounting seat 103, a fixing frame 105 is installed on the top of the support plate 104, and a driving drum 106 is installed inside the fixing frame 105, a positioning and fixing mechanism 107 is rotatably installed inside the driving drum 106 through a bearing, a cutting mechanism 108 is installed on the inner wall of the shell body 101, and a driving cutting tool 109 is installed on the side wall of one side of the cutting mechanism 108, and a driving mechanism 1010 is installed at one end of the fixing frame 105.
