Description

Technical Field

[0001] The utility model relates to cutting technology, in particular to laser cutting equipment. Background Art

[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, and 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, the material is eventually cut, thereby achieving the purpose of cutting. When using laser cutting to cut a full circle or arc on a steel plate, the cutting angle must be set first, and then the cutting is performed. Due to operational requirements or structural problems, the cutting angle is limited and can only be cut within 0-360°. When cutting to 360-0°, it will stop, resulting in an uneven cut in the last cut, affecting the cutting quality. In addition, during cutting, staff supervision is required, which affects the processing of other workstations of the staff, and it is not convenient to stop automatically after the cutting is completed.
