Technical Field

[0001] The utility model relates to the technical field of laser cutting, in particular to an automatic grinding device for a round tube laser cutting end. Background Art

[0002] Laser cutting uses a high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature and evaporates to form holes. As the beam moves across the material, the holes continuously form narrow slits to complete the cutting of the material. During the use of the circular tube laser cutting machine, the end face of the cutting head will be worn and deformed, which will affect the cutting quality and accuracy. Therefore, regular grinding of the cutting head end face is a necessary maintenance measure.
