Description

TECHNICAL FIELD

[0002] The laser cutting equipment uses high-energy laser beams to irradiate the surface of the material, which makes the material rapidly melt, vaporize or reach the ignition point, and at the same time, the melted or burned material is blown away by high-speed airflow, thereby realizing cutting. In particular, in the power tower industry, it is suitable for processing large and long strip-shaped plates in power tower manufacturing, and for large amount of bevel processing of workpieces, mainly thick plates.
