Laser cutting is to focus the laser light emitted from the laser into a laser beam with high power density through an optical path system. The laser beam irradiates the surface of the workpiece to make the workpiece reach the melting point or boiling point, and the high-pressure gas coaxial with the beam blows away the melted or vaporized metal. With the movement of the relative position between the beam and the workpiece, the material finally forms a slit, so as to achieve the purpose of cutting.
Laser cutting processing replaces the traditional mechanical knife with invisible light beam. It has the characteristics of high precision, fast cutting, not limited to the cutting pattern, automatic typesetting, saving materials, smooth cutting, and low processing cost. It will gradually improve or replace the traditional metal cutting process equipment. The mechanical part of the laser cutter head has no contact with the work, and will not scratch the working surface during the work; The laser cutting speed is fast, the incision is smooth and flat, and generally there is no need for subsequent processing; The cutting heat affected zone is small, the plate deformation is small, and the cutting seam is narrow (0.1mm ~ 0.3mm); The notch is free of mechanical stress and shear burr; High processing accuracy, good repeatability, and no damage to the material surface; CNC programming, can process any plan, can cut the whole board with a large format, no need to open a mold, economy and time saving.
Application industry of laser cutting machine:
1. Decoration industry
Due to the fast speed and flexible cutting of the laser cutting machine, many complex graphics can be rapidly formed, which is deeply loved by decoration companies. As long as they are what customers want, they can directly cut them out using relevant materials after making the drawings through CAD, and customization has no problem at all.
2. Automobile industry
Many edges and corners in the automobile industry, such as car doors, car exhaust pipes and so on, need to be treated if they are formed manually*/* The accuracy is difficult to achieve, and the second efficiency is many. The robot laser cutting machine can quickly process in batches.
3. Advertising industry
The advertising industry is very customized, and the efficiency of traditional methods is very low. Laser cutting machines are very suitable for this industry. No matter what kind of words, no matter how many different companies, they can be cut out quickly.
4. Kitchenware industry
Now there are more and more houses, more and more decoration, and more and more demand for kitchenware related products. The laser cutting machine is very suitable for cutting thin stainless steel, with high speed, high accuracy and good effect. It can also realize customization and personalized product development, which is deeply loved by kitchenware manufacturers.
5. Lighting industry
At present, the mainstream outdoor lamps and lanterns are all large pipes, cut in different types, and there are more and more retro products. The traditional cutting method is too inefficient and cannot achieve personalized development. The use of laser cutting machines just solves this problem.
6. Sheet metal processing
To put it simply, processing is the cutting of all kinds of plates and various graphic parts. The advantages of laser cutting machines are fully developed in this industry.
7. Cabinet industry
Including power distribution cabinets, file cabinets and so on, they are all standardized production of thin plates, requiring efficiency. It is very suitable to use four or six stations of laser cutting machines, with high efficiency. For specific plates, they can even be cut in two layers.
8. Fitness equipment
Due to the state's attention to sports and health and the development of personal health concepts, square fitness equipment and household fitness equipment have developed rapidly, with a particularly large demand. Basically, they are pipe cutting. It is very convenient and fast to use pipe laser cutting machines.
Treatment method of smoke and dust generated by laser cutting machine:
1. Exhaust treatment:
The exhaust treatment of laser cutting machine is generally only aimed at local operation. For example, the general exhaust facilities are used at the fixed position of the operator to prevent the local working place from being polluted by harmful substances. However, the effect of this method is very low, because the laser cutting smoke and harmful gases are spread from the source to the whole production environment with air as the medium.
2. General ventilation:
Comprehensive ventilation includes natural ventilation and mechanical ventilation. In foreign countries, natural ventilation is generally used for outdoor numerical control cutting operations or open space numerical control cutting, and mechanical ventilation is generally used for indoor operations. The welding smoke in the workshop is discharged outdoors through axial flow fans installed on the wall or ceiling, or recycled in the workshop after purification by purifiers, so as to reduce the smoke concentration in the workshop.
3. Dust treatment of industrial dust collector:
In the process of processing, a suitable smoke purifier is used to effectively treat the smoke and dust, which is also a method currently in line with the national environmental protection requirements. A dust collector is set under the laser cutting workbench and collected into the dust box of the industrial dust collector through the pipeline. The smoke and dust generated by cutting will not be spread into the processing workshop, which not only ensures the cleanliness of the workpiece, but also ensures the health of workers.
