[0002] Boring tools are a type of holemaking tool, primarily used for internal hole machining, hole enlarging, and profiling. Based on their structure, they can be categorized into various types, including single-edge, double-edge, fine-adjustment, and modular. Boring tools are commonly used to create circular holes within workpieces and are primarily used in machine tool manufacturing, automotive manufacturing, aerospace, shipbuilding, and mold processing. In these fields, boring tools can produce high-precision holes, meeting a variety of complex machining requirements.

[0003] In the prior art, a boring tool for a boring machine disclosed in announcement number CN212217116U includes a tool arm and a cutting edge connected to one end of the tool arm, and the other end of the tool arm is connected to a fixed tool holder, and the tool arm and the fixed tool holder form a U-shaped structure. The tool of the utility model can be used to process the back of the workpiece well without forming chatter marks on the processing surface of the workpiece, thereby ensuring the smoothness of the processing surface of the workpiece.

[0004] Although the above technical solution can process the surface of the workpiece well by the tool without forming chatter marks on the machined surface of the workpiece, it is impossible to adjust the boring diameter of the tool during use. When processing holes of different diameters, the boring tool needs to be replaced, which has poor practicality. In view of this, a boring tool with an extended structure is provided to overcome the above defects. Utility Model Content
