Principles and applications of sheet metal laser processing

When the laser beam is focused on the surface of the sheet metal, its energy is highly concentrated, causing the local temperature of the material to rise sharply. During the cutting process, the laser beam moves along a predetermined path, and the melted or vaporized material is blown away by the auxiliary gas to form a slit. For the punching operation, the laser beam continues to act on a point on the sheet metal until it penetrates the material. During welding, the laser beam heats the contact area of ​​the two sheets of metal to a molten state, causing them to fuse together.

Advantages of sheet metal laser processing

High precision

Laser processing can achieve very fine cutting and punching, with an accuracy of millimeters or even microns. This is crucial for some sheet metal processing tasks that require extremely high dimensional accuracy. When processing Automotive Mechanical components, such as some precision sheet metal brackets in the engine compartment, laser processing can ensure that the dimensions of the components are accurate, thereby ensuring the stable operation of the entire engine system.

High speed

Compared with traditional mechanical processing methods, sheet metal laser processing is faster. It can complete the cutting of complex shapes or the processing of a large number of holes in a short time. This greatly improves production efficiency, especially for mass production.

High flexibility

Through computer programming, laser processing can easily realize the processing of various complex shapes. Whether it is a straight line, a curve or an irregular shape, it can be accurately presented on the sheet metal. This flexibility enables it to meet the diverse needs of different customers.

High processing quality

The heat affected zone generated by laser processing is small, and it has little effect on the performance of sheet metal materials. The processed edges are smooth and burr-free, which reduces the workload of subsequent processing. Moreover, laser processing can be carried out without contacting the sheet metal material, avoiding material deformation caused by mechanical stress.

Application fields of sheet metal laser processing

Sheet metal processing industry

In traditional sheet metal processing, laser processing is gradually replacing some traditional cutting and punching methods. It can process sheet metal materials of various types and thicknesses, whether it is thin or thick, and can obtain good processing results. For example, when making metal chassis, cabinets and other products, laser processing can accurately cut the shape of each panel and punch mounting holes.

Commercial Auto Spares

The production of auto parts requires high precision and quality. Sheet metal laser processing is widely used in the manufacture of auto parts. The body panels, interior parts, etc. of the car can be cut to obtain precise shapes by laser cutting. For some auto parts that need to be customized, such as special decorative parts for modified cars, laser processing can be quickly produced according to the customer's design requirements.

Automotive Mechanical componer and Chassis

In the manufacture of automotive mechanical parts and chassis, laser processing plays an important role. Some reinforcement plates on the chassis and sheet metal parts of suspension parts can be cut and welded by laser to ensure their strength and precision. In the processing of automotive mechanical parts, laser drilling can be used to manufacture precise structures such as injection holes in the lubrication system to ensure the normal function of the parts.
