[0001] The utility model relates to the technical field of fixing devices, in particular to a fixing tool for a numerically controlled machine tool. Background Art

[0002] Computer Numerical Control (CNC) machine tools have become the mainstay of modern manufacturing. They use computer programs to control the precise movement of tools, achieving high-precision machining of complex parts. However, CNC machine tools alone cannot complete the machining of workpieces, because workpieces require stable clamping, accurate positioning and reliable support. This is the importance of CNC machine tool fixtures.
