Description

Technical Field

[0001] The invention relates to the field of precision parts laser cutting, and in particular to a precision parts laser cutting machine. Background Art

[0002] The laser cutting machine uses a high-power density laser beam to irradiate the surface of the workpiece, causing the workpiece to reach its melting point or boiling point. At the same time, 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. During this process, the laser beam is focused into a high-power density spot through the optical path system, and the diameter of the focus can reach the micron level, thereby achieving high-precision cutting.
