[0018] The following is combined with Figure 1 —3 Provide further details of this application.

[0019] The present application embodiment discloses a milling cutter connector for a CNC lathe. Figure 1 A milling cutter connecting piece for a CNC lathe is used for installing and fixing a milling cutter for a CNC lathe, comprising a sleeve 1, which is a prior art product. The sleeve 1 is used to conveniently install the device as a whole on a CNC lathe (the installation of the sleeve 1 is a prior art product, so no further elaboration is required). A milling cutter body 2 is sleeved on the inner side of the sleeve 1. The milling cutter body 2 is a prior art product. The milling cutter body 2 is used to facilitate processing of a workpiece. A chuck 3 is provided on one side of the sleeve 1. The chuck 3 is a prior art product. The chuck 3 is used to facilitate initial clamping and fixing of the milling cutter body 2. The milling cutter body 2 is sleeved inside the chuck 3. A fixing component 4 is provided on the sleeve 1. The fixing component 4 is used to facilitate re-fixing of the milling cutter body 2, thereby improving the fixing effect.

[0020] When installing the milling cutter body 2, first put one end of the milling cutter body 2 inside the chuck 3, then insert the end of the milling cutter body 2 into the sleeve 1, fix the milling cutter body 2 for the first time through the chuck 3, and then fix the milling cutter body 2 again through the fixing component 4 on the sleeve 1. During subsequent processing, install the sleeve 1 on the CNC lathe so that the CNC lathe drives the milling cutter body 2 to process the workpiece.
