Laser drilling technology is the earliest practical laser technology in laser material processing technology. Laser drilling in sheet metal workshop is generally used pulse laser. It has high energy density and short time. It can process 1 micron holes. It is especially suitable for processing holes with certain angles and thin materials. It is also suitable for processing deep holes and micro holes in parts with high hardness or brittle soft materials.
Laser can drill the burner parts of gas turbine. The punching effect can realize three-dimensional direction and the number can reach thousands. Perforated materials include stainless steel, nickel chromium iron alloy and Haas Tero (HASTELLOY) based alloy. Laser drilling technology is not affected by the mechanical properties of materials, and automation is relatively easy.
With the development of laser drilling technology, laser cutting machine has realized automatic operation. The application of laser cutting machine in sheet metal industry has changed the processing method of traditional sheet metal technology, realized unmanned operation, greatly improved the production efficiency, realized full automatic operation, promoted the development of sheet metal economy, and in the aspect of punching effect. It improves the grade, and the effect is remarkable.
