Description

Technical Field

[0001] The utility model relates to the technical field of steel plate cutting, in particular to a steel plate rectangular hole laser cutting machine. Background Art

[0002] Laser cutting replaces traditional mechanical knives with invisible beams. It features high precision, fast cutting speed, no restrictions on cutting patterns, automatic typesetting to save materials, smooth cuts, and low processing costs. It will gradually improve or replace traditional metal cutting equipment. The mechanical part of the laser cutter head does not contact the workpiece and will not scratch the workpiece surface during operation. Laser cutting is fast, with smooth cuts and generally no need for subsequent processing. The heat-affected zone is small, plate deformation is small, and the cutting kerf is narrow (0.1mm to 0.3mm). The cut is free of mechanical stress and shear burrs. It has high processing precision, good repeatability, and does not damage the material surface. CNC programming allows for processing of any plane pattern and can cut large panels without the need for molds, saving time and money.
