A laser cutting machine focuses the laser emitted from the laser into a high-power laser beam through an optical path system. The laser beam irradiates the surface of the workpiece, causing it to reach the melting or boiling point, while the high-pressure gas coaxial with the beam blows away the melted or vaporized metal.
As the beam of light moves relative to the workpiece, the material eventually forms a cutting seam, thereby achieving the purpose of cutting. One of the advantages of laser cutting machines is the high energy density of the beam, usually 10W/cm2.
Due to the inverse ratio between energy density and area, the diameter of the focal spot should be kept as small as possible to produce a narrow slit; At the same time, the diameter of the focal spot is also proportional to the focal depth of the lens. The smaller the focal depth of the focusing lens, the smaller the diameter of the focal spot.
Extended Information:
Laser cutting processing replaces traditional mechanical knives with invisible beams of light. It has the characteristics of high accuracy, fast cutting, not limited to cutting pattern limitations, automatic layout saving materials, smooth cuts, and low processing costs. It will gradually improve or replace traditional metal cutting process equipment.
The incision is free of mechanical stress and shear burrs; High machining accuracy, good repeatability, and no damage to the material surface; CNC programming, capable of processing any flat plan, capable of cutting large entire boards without the need for mold opening, economical and time-saving.
