[0028] From the above description, it can be seen that the above embodiments of this utility model achieve the following technical effects: The machine tool body 1 can utilize an idle CNC lathe. When the user needs to chamfer the plate body 2, the plate body 2 is lifted and placed against one side of the movable seat 16. Simultaneously, the plate body 2 is supported by the provided support column 26. Then, the second movable plate 8 is rotated to block the plate body 2, and the second threaded column 9 is tightened, so that the second movable plate 8... The mounting plate body 2 is pressed and fixed, thereby connecting the water pipe 20 to the water source. Controlling the water source allows water to spray from the pipe 20. Then, the cutting head of the machine tool body 1 is activated, causing the rotating block 17 and the cutting head 18 to rotate. This activates the drive motor 12, driving the first threaded post 6 to rotate. The first threaded post 6 and the first threaded hole 5 convert rotational motion into linear motion, causing the first moving plate 4 to move the moving seat 16 and the mounting plate body 2 closer to the rotating cutting head 18. This chamfers the large circular hole on one side of the mounting plate body 2. Simultaneously, through the set... Drive mechanism 14, when activated, drives the third threaded post 13 to rotate, causing the third threaded post 13 and the third threaded hole 15 to convert rotational motion into linear motion. This causes the moving block 11 to move inside the limiting hole 10, driving the moving seat 16 and the plate body 2 to move laterally, thereby adjusting and positioning the plate body 2 so that the rotating cutting head 18 can accurately chamfer the hole in the plate body 2. During chamfering, water is poured onto the chamfered area through the water pipe 20 to cool it down. Debris enters the water collection hopper 21 with the water flow and flows to the drain. The water enters the water collection chamber 25 from the inside of the water tank 24, thereby achieving the effect of chamfering one side of the hole of the plate body 2. The plate body 2 is moved and positioned by the set drive motor 12, drive mechanism 14, moving seat 16 and first moving plate 4, so that the plate body 2 is accurately aligned with the rotating cutting head 18 for chamfering. By using an idle CNC lathe as the main body of the machine tool 1, it is not necessary to use a high-precision CNC machining center, avoiding the occupation of the production of other workpieces, which is convenient to use and more practical.
