Sheet metal chassis is a kind of case for sheet metal to be formed by comprehensive cold working process. Its processing technology includes cutting, stamping, cutting, compounding, folding, welding, riveting, splicing, forming (such as car body), etc. its remarkable feature is that the thickness of parts is the same. With the application of sheet metal more and more widely, the design of sheet metal parts has become very important in the development of product industry To a part, mechanical engineers must master the design skills of sheet metal parts。

The processing steps of the parts in the sheet metal workshop are: pre test, trial production and mass production. In the trial production stage of product processing, we should communicate with customers in time, get the corresponding processing evaluation, and then carry out mass production。

Laser drilling technology is the earliest practical laser technology in laser material processing technology. In the sheet metal workshop, laser drilling generally uses pulse laser, which has high energy density and short time, and can process 1 μ m small hole. It is especially suitable for processing small holes with certain angle and thin materials, as well as deep holes and micro holes of parts with high strength, high hardness or brittle soft materials。

Laser can be used to drill the gas turbine burner, and the drilling effect can achieve three-dimensional direction. The materials that can be drilled include stainless steel, nickel chromium iron alloy and Hastelloy (Hastelloy) based alloy. Laser drilling technology is not affected by the mechanical properties of materials and is easy to realize automation。

With the development of laser drilling technology, the automatic operation of laser cutting machine has been realized. The application of laser cutting machine in sheet metal industry has changed the processing method of traditional sheet metal process, realized unattended operation, greatly improved the production efficiency, realized the automatic operation of the whole process, promoted the economic development of sheet metal, improved the drilling effect, and achieved remarkable processing effect。
