Description

Technical Field

[0001] The invention relates to the technical field of laser cutting, and in particular to a high-precision laser cutting device. Background Art

[0002] Laser cutting is a metal processing technology that uses a high-power density laser beam as a heat source. Through computer-aided design and manufacturing technology, it irradiates the workpiece according to a predetermined cutting trajectory, causing the material to melt, vaporize or burn rapidly, thereby achieving the purpose of cutting.

[0003] At present, the tool used for laser cutting is a laser cutter. The laser cutter 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 to make the workpiece 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 cut is eventually formed in the material, thereby achieving the purpose of cutting.

[0004] When an existing laser cutter is in use, the device often causes the placed material to shift due to mechanical vibration. When the material to be laser cut shifts due to the vibration of the device, the accuracy of cutting the material will be reduced, resulting in low-quality products.
