Description

Technical Field

[0002] The laser cutting machine focuses the laser emitted from the laser into a high-power density laser beam through the optical path system. The laser beam irradiates the surface of the workpiece, causing the workpiece to reach the melting point or boiling point. At the same time, the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the relative position of the beam and the workpiece moves, a slit is eventually formed in the material, thereby achieving the purpose of cutting. Laser cutting processing has the characteristics of high precision, fast cutting, no limitation on cutting patterns, automatic typesetting to save materials, smooth incisions, and low processing costs. It is widely used, for example, a laser cutting machine can be used to cut a sheet into a finished product of a specified shape.
