Description

Technical Field

[0001] The utility model relates to the technical field of laser drilling, in particular to a laser cutting precision drilling device. Background Art

[0002] Laser cutting uses a focused high-power density laser beam to irradiate the material to be cut, so that the material is quickly heated to the vaporization temperature, and the irradiated material is quickly melted, vaporized, ablated or reaches the ignition point, thereby evaporating to form holes. As the beam moves on the material, the holes continuously form a very narrow (such as about 0.1mm) cut. At the same time, the molten material is blown away by a high-speed airflow coaxial with the beam, thereby achieving the cutting of the workpiece.
