With the development of laser technology, laser cutting machines have been widely used in various industries, and its uses are very wide. Different types and processes of laser cutting machines have different uses. Today, Leapion Laser Manager will share with you the main uses of their respective laser cutting machines, as follows:
Laser cutting gasification refers to the use of high-energy-density laser beams to heat the workpiece, so that the temperature rises rapidly, part of the material vaporizes into steam and disappears, and part of the material is blown away by the auxiliary gas stream from the bottom of the slit as a spray. The spraying speed of the steam is very high, and at the same time the steam is sprayed, a cut is formed in the material. Laser vaporization cutting is mostly used for cutting extremely thin metal materials and non-metal materials, such as paper, cloth, wood, plastic, and rubber.
During laser melting and cutting, the metal material is melted by laser heating. After the workpiece is partially melted, the molten material is sprayed out with the help of air flow to form an incision. Laser melting and cutting do not need to vaporize the metal completely, and the energy required is only 1/10 of that of vaporized cutting. Laser melting cutting is mainly used for cutting some non-oxidized materials or active metals, such as stainless steel, titanium, aluminum and their alloys.
The material is ignited under the irradiation of the laser beam and undergoes a fierce chemical reaction with oxygen to generate another heat source to further heat the material, which is called oxidative melting and cutting. Due to the large amount of heat generated by the oxidation reaction in the cutting process, the energy required for laser oxygen cutting is only 1/2 of that of melting and cutting. The same thickness of structural steel has a higher oxidation cutting rate, which is much greater than laser vaporization and melting cutting. . Laser oxygen cutting is mainly used for easily oxidized metal materials such as carbon steel, titanium steel and heat-treated steel.
This process means that a small area of brittle material is heated by a laser beam, which causes a large thermal gradient and severe mechanical deformation in this area, leading to the formation of cracks in the material. Simply put, it is high-speed and controllable cutting by laser beam heating, which is called controlled fracture cutting. It is mainly used for brittle materials that are easily damaged by heat.
According to different cutting materials, it can be divided into two types: metal laser cutting machine and non-metal laser cutting machine. This is a good distinction. Metal laser cutting machines are used to process metal materials, while non-metal laser cutting machines are required to cut non-metal materials.
According to different lasers, it can be divided into CO2 gas lasers, fiber lasers, and FPC ultraviolet lasers.
CO2 laser cutting machine is generally used for cutting non-metallic materials; fiber laser cutting machine is suitable for cutting metal sheets and pipes; UV laser cutting machine can be used in many fields in flexible board production, including FPC profile cutting and contour cutting , Drilling, window covering with film, uncovering and trimming of soft and hard board, cutting of mobile phone case, cutting of PCB shape and so on.
According to the laser output power classification, it can be divided into three types: high power laser cutting machine, medium power laser cutting machine, and low and low power laser cutting machine. The laser output power required by different application fields is also different. In the industrial field, high-power fiber laser cutting machines are the main ones, while in the laser engraving field, the medium-power laser engraving and cutting machines are the main ones.
The sheet format that the laser cutting machine can cut is divided into two types: standard format and large format. The cutting length of the large-format laser cutting machine in the X-axis direction is more than 8000mm, and the cutting width in the Y-axis direction is more than 2500mm. The cutting area of the standard-format laser cutting machine is generally about 3000mm×1500mm, 4000mm×2000mm.
According to the structure of the cutting machine tool, it can be divided into two types: cantilever laser cutting machine and gantry laser cutting machine. The cantilever laser cutting machine adopts an open structure, which is convenient for loading and unloading, and has a low cost. It is welcomed by small and medium-sized owners. The gantry laser cutting machine adopts bilateral drive mode, which has good dynamic performance, high cutting efficiency, and stable and reliable long-term operation.
According to the size of the laser cutting machine. It can be divided into small laser cutting machine and large laser cutting machine. Generally, small laser cutting machines are used in industries such as advertising signs and metal crafts. Large laser cutting machines are mainly used in sheet metal processing, aerospace, machinery manufacturing and other industries.
In short, the application of metal laser cutting machine is very extensive, covering many industries, and it is one of the necessary equipment for many companies. For example: advertising sign production, sheet metal processing, chassis cabinet production, subway parts, kitchen utensils, automobile industry, etc.
Moreover, almost all materials in the electronics industry can be solved efficiently with laser cutting machines. Ultra-high-power laser cutting machines are also easy to use in the aerospace field. There may be another thing you don't know. In fact, laser cutting machines used to be dedicated to high-end fashion design. Nowadays, laser cutting can often be seen at fashion shows or retailers such as Topshop or ASOS.
It can be seen that the use of laser cutting machine is very wide. How to choose the right machine is mainly based on our own processing needs. If you want to know more professional questions, please consult Leapion Laser.
