Figure 1 The system includes a drill rod 1, with one end being a drive end 11 and the other end being a cutting end 12. A cutting tool 13 is provided on the cutting end 12, and a polishing component 14 and a vibration damping component 15 are also provided on the outer periphery of the drill rod 1. The drive end 11 is used to connect to an external drive and drive the drill rod 1 to rotate around its own axis so that the cutting tool 13 can be used to cut and form a hole. The polishing component 14 and the vibration damping component 15 are both used to fit and support the inner wall of the hole and can rotate with the drill rod 1.

[0022] In the narrow and deep hole machining process, an external drive drives the drive end 11 of the drill rod 1, causing the entire drill rod 1 to rotate along with the cutting tool 13, the polishing part 14, and the vibration damping part 15. The cutting tool 13 cuts to form a hole, the polishing part 14 extrudes and polishes the machined hole wall to remove burrs, and the vibration damping part 15 supports the hole wall, which can improve the rotation accuracy of the drill rod 1 and reduce vibration and shaking. Thus, the large depth-to-diameter ratio integrated deburring and hole-forming tool provided in this embodiment combines the advantages of rotational self-guiding, drilling, vibration damping, and deburring into one, improving the performance of the cutting tool 13 while avoiding multiple machining processes, and achieving high-quality, high-efficiency, and low-cost machining.

[0026] The polishing strip 141 is parallel to the axial direction of the drill rod 1 along its length, so that the polishing strip 141 has the largest polishing area on the hole wall, which can improve the polishing efficiency of the inner wall; it is set close to the cutting end 12, so that as the tool 13 cuts and forms a hole, the polishing strip 141 can follow closely to polish.

[0027] In an optional embodiment, more preferably, the polishing component 14 further includes a brush 142, which is disposed on the side of the polishing strip 141 away from the cutting end 12; the brush 142 can rotate with the drill rod 1 to clean the inner wall of the hole.

[0028] The brush 142 can further remove burrs from the hole wall on the basis of polishing by the polishing strip 141, thereby improving the surface quality of the hole wall. The brush 142 can be fixed to the outer periphery of the drill rod 1 by means of bonding or embedded bolts.

[0029] In the optional embodiments of this example, it is more preferred that the polishing strip 141 is made of cemented carbide; the cemented carbide material ensures that the polishing strip 141 has sufficient strength and service life.

[0032] Among them, the damping strip 151 can always support the hole wall, playing the role of damping support; specifically, the outer diameter of the cutting tool 13 is the same as the outer diameter of the polishing part 14 and the damping part 15, so as to achieve cutting, polishing and damping support of the hole wall, improve the rotation accuracy of the drill rod 1 and reduce vibration and shaking.

[0033] In the optional scheme of this embodiment, it is more preferred that the vibration damping strip 151 is made of resin material; the elasticity of the resin material itself can meet the requirements of vibration reduction and noise reduction.
