♪ 1. Process Description
304 stainless steel laser cutting uses a high-power fiber laser beam to irradiate the surface of stainless steel sheets, rapidly melting the material while auxiliary gas blows away molten slag, achieving high-precision two-dimensional shape cutting. Suitable for precision components, electronic device parts, and related applications.
