Laser cutting technology has the characteristics of processing controllable, high efficiency and high quality. It has very wide applications in industrial processing, such as automotive industry, textile machinery, sheet metal processing and so on. Laser pointer cutting can be divided into laser vaporization cutting, laser melting cutting, laser oxygen cutting and laser dicing and control fracture. Due to the late start of laser technology in China, the cutting core technology relies on imports, which has led to the slow development of high-end laser cutting in China.
However, in recent years, with the promotion of “Made in China 2025”, laser cutting technology is also facing changes and opportunities. The change means that laser companies must not only increase investment in cutting technology, but also adapt to the trend of industrial automation, making laser cutting more personalized. At the same time, laser companies will also have greater opportunities, laser cutting technology is improving industrial processing. There is an irreplaceable advantage in efficiency. The development of industrial control technology has brought more possibilities to the laser industry. The cutting technology will expand to more fields in the future and contribute to the development of the industry.
According to industry insiders, laser cutting will develop in these directions in the future. High-speed, high-precision cutting technology, thick plate cutting and large-size workpiece cutting, three-dimensional multi-axis CNC laser cutting technology, unmanned and automated laser cutting technology The main research direction.
The laser cutting machine is the most direct device for laser cutting technology. It is a laser beam emitted from a laser, which is focused into a high power density laser beam through an optical path system. The laser beam is irradiated onto the surface of the workpiece to bring the workpiece to a melting point or boiling point, while the high-pressure gas coaxial with the beam blows away the molten or vaporized metal. As the beam moves relative to the workpiece, the material is finally slit, thereby achieving the purpose of cutting.
As an emerging sheet metal processing equipment, laser cutting machine has been updated and developed by laser pointer technology, laser cutting process and laser cutting machine equipment, which are familiar and accepted by the majority of sheet metal processing enterprises, and with high processing efficiency. With the advantages of high processing precision, good cutting section quality, and three-dimensional cutting processing, many advantages such as plasma cutting, water cutting, flame cutting, and CNC punching are gradually replaced. According to the different laser generators, laser cutting machines on the market can be roughly divided into three types: CO2 laser cutting machine, solid (YAG) laser cutting machine, and fiber laser cutting machine.
