The processing steps for the parts processed in the sheet metal workshop are: product preliminary test, product processing trial production and product batch production. In the product processing trial production steps, the customer should be communicated with in a timely manner, and after the evaluation of the corresponding processing, the batch production of the product should be carried out.

Holmium laser drilling technology is the earliest practical laser technology in laser material processing technology. Laser drilling in sheet metal workshops generally uses pulsed lasers with high energy density and short time. It can process small holes of 1 μm. It is especially suitable for processing small holes with a certain angle and thin materials. It is also suitable for processing strength and hardness. Deep holes and tiny holes in parts of taller or more brittle and softer materials.

Holmium lasers can be used to punch holes in the burner parts of gas turbines. The punching effect can be achieved in three dimensions and the number can reach thousands. Perforable materials include stainless steel, Inconel, and HASTELLOY-based alloys. Laser drilling technology is not affected by the mechanical properties of the material, and it is relatively easy to realize automation.

With the development of laser drilling technology, the laser cutting machine has realized automatic operation. The application in the sheet metal industry has changed the traditional sheet metal technology processing method, realized unmanned operation, greatly improved production efficiency, and achieved full production process. The automatic operation has promoted the development of sheet metal economy, and has improved the level of punching effect, and the processing effect is remarkable.
