[0001] The utility model relates to the field of drill bits, in particular to a CNC machine tool drill bit with an anti-shake mechanism. Background Art

[0002] CNC machine tools are short for Computer numerical control machine tools, which are automated machine tools 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. After calculation and processing, the CNC device sends various control signals to control the movement of the machine tool and automatically process the parts according to the shape and size required by the drawing.

[0003] In the existing technology, CNC machine tools have better solved the problems of complex, precise, small-batch, and multi-variety parts processing. They are flexible, high-efficiency automated machine tools, representing the development direction of modern machine tool control technology, and are a typical mechatronics product. CNC machine tools are generally equipped with drill bits, which are used to drill holes.

[0004] However, due to the large pressure generated when the drill bit and the part move relative to each other, and the drill bit is not a regular part, the drill bit will shake when rotating, resulting in inaccurate drilling. At the same time, most existing drill bits are composed of a drill rod and a drill bit, with a single structure and lack of stability, making it more prone to shaking during the processing process.
