Comparison of laser cutting technology and laser engraving technology

The application of laser technology in daily life is so-called commonplace. For friends in the processing industry, laser cutting technology and laser engraving technology are often used, but from the processing principle and operation point of view, there is no big deal. The difference, but the operation process is not the same, let's introduce it to you.　 　　 1. Laser cutting technology 　　 we can understand it as the separation of edges. For such processing purposes, we should first make the graphics in the form of vector lines in CORELDRAW, AUTOCAD, pneumatic marking machine, and then save the corresponding PLT, DXF format, use the laser cutting machine operating software to open the file, according to our The processed material can be run after setting the parameters such as energy and speed. The laser cutting machine will automatically cut according to the flight path generated by the software after receiving instructions from the computer. The technology of laser cutting mainly includes laser gasification cutting, laser flame cutting, laser melting cutting and so on.　　2. Laser engraving technology 　　Laser engraving processing is based on numerical control technology, and laser is the processing medium. The physical modification of the processed material instantaneously melted and vaporized under laser irradiation to achieve the purpose of processing. Laser processing characteristics: no contact with the surface of the material, unaffected by mechanical movement, the surface will not be deformed, and generally do not need to be fixed. Not affected by the elasticity and flexibility of the material, it is convenient for soft materials. The processing precision is high, the speed is fast, and the application field is wide.　　Laser engraving is mainly divided into two types: bitmap engraving and vector engraving. In addition to laser cutting and laser engraving, other laser processing systems include: lasers, light guide systems, processing machine tools, control systems, and detection systems; laser treatment: it can be used for surgical operations to relieve pain and reduce infections; laser imaging : Use the laser beam to scan the object, reflect the reflected beam back, get different arrangement order and imaging and many other applications.
