[0002] Laser tube cutting technology is an advanced technology that uses high-energy laser beams to cut tubes. The principle is to focus the high-energy laser beam on the surface of the tube, and use the interaction between the high-energy photons of the laser and the surface material of the tube to quickly melt, vaporize or ignite the material, and at the same time use auxiliary gas to blow away the melted or burned part, thereby achieving tube cutting. Laser tube cutting technology has many advantages, such as high precision, high efficiency, low cost, etc., so it has been widely welcomed.

[0003] When laser tube cutting is performed, in order to facilitate the placement of the tube, corresponding supports are usually provided on the laser tube cutting machine. As the laser tube cutting technology matures, the range of tube diameters that can be cut is getting larger and larger.
