The optical fiber laser cutting machine has great advantages in cutting thin plates within 4mm, because it can transmit through optical fiber, its flexibility has been improved unprecedentedly, there are few fault points, and it is easy to maintain and fast. However, due to the influence of solid laser wavelength, the quality of optical fiber laser cutting machine is poor when cutting thick plates. The wavelength of the optical fiber laser cutting machine is 1.06um, which is not easy to be absorbed by nonmetals, so it cannot cut nonmetallic materials. The photoelectric conversion rate of fiber laser exceeds 25%. Fiber laser has obvious advantages in power consumption, supporting cooling system, etc. According to the safety standards, the laser hazard level is divided into four levels. Due to the short wavelength of the fiber laser, it is harmful to the human body due to the great harm to the eyes. For safety reasons, fiber laser processing requires a completely enclosed environment. As we all know, the domestic steel plate laser cutting machine has a long history, and the development of all major industries can not be separated from this advanced laser equipment. With the development of science and technology and social progress, let's explore the brilliant steel plate laser cutting machine.

Steel plate refers to flat steel or rectangular steel, which is pressed after pouring and cooling by molten steel. It can be made directly or cut with wide steel strip. In the traditional sense, the thickness of steel plate is 0.2-4mm, which is greater than 4mm. Then, due to its high density and special properties, the steel plate has been widely used in automobiles and ships, aviation, hardware, mechanical equipment, etc. Therefore, the role of laser cutting machine is very prominent and important.

Characteristics of optical fiber laser cutting machine for precision steel plate

Main advantages: high photoelectric conversion rate, low power consumption, can cut stainless steel plates and carbon steel plates within 12mm. It is the fastest laser cutting machine among the three machines, with small slit, good spot quality, and can be used for fine cutting. Main disadvantages: At present, most of the core technologies and key technologies of fiber lasers are in the hands of one or two manufacturers in Europe and the United States, so most of the machines are expensive, most of which are more than 1.5 million yuan, while the low-power ones are about 500000 yuan. Due to the thin slit of optical fiber (especially in nitrogen cutting), the gas consumption is huge. In addition, fiber laser is difficult to cut aluminum, copper and other high reflectivity materials, and the cutting speed is very slow. Main market positioning: cutting below 12mm, especially for high-precision processing of thin plates, mainly for manufacturers with high requirements on processing accuracy and efficiency. It is estimated that with the emergence of 5000W and above lasers, fiber laser cutting machine will eventually replace most CO2 high-power laser cutting machine markets.

First, it has the advantage of good performance. As we all know, this optical fiber laser cutting machine is a high-tech automatic laser processing equipment, integrating laser cutting, precision machinery, motion control and other technologies. It has a stable steel frame main body and beam structure, so it can achieve stable invariance, high-speed and high-precision cutting effect.

Therefore, the steel plate laser cutting machine has been deeply loved by people and led the market since it came out. With more and more applications, the proportion of fiber laser cutting machines is getting higher and higher, which poses a challenge to the application of carbon dioxide lasers. The energy consumption of fiber lasers is very low, accounting for only one third of that of CO2 lasers. Secondly, due to the wavelength, the absorptivity of metal materials to fiber lasers is much higher than that of carbon dioxide lasers. In the field of thin metal plate cutting, optical fiber laser equipment has completely surpassed carbon dioxide laser equipment. It is mainly used in sheet metal processing, aviation, aerospace, electronics, electrical appliances, automobiles, machinery, precision accessories, ships, metallurgical equipment, elevators, household appliances, craft gifts, decoration, kitchenware processing and other manufacturing and processing industries.
