Application Of High Power Laser Cutting In Sheet Metal Processing

Laser technology is one of the four major inventions in the twentieth century, along with atomic energy, semiconductors and computers. It is known as “the fastest knife”, “the most accurate ruler” and “the brightest light”. However, the technology did not break through the original technical bottleneck until the 21st century. At the same time, the combination of laser technology and advanced equipment promoted the development of advanced equipment manufacturing industry. The word sheet metal is not unfamiliar to everyone.

Almost all manufacturing industries will have sheet metal processing. If you count the cutting process of sheet metal (the thickness of the metal sheet is below 6mm), it is nothing more than laser cutting, plasma cutting, and flame cutting. , shearing machine, stamping, etc. Compared with the traditional shearing process, laser cutting has the advantages of higher cutting accuracy, higher material utilization and productivity. As a precise processing method, laser cutting can process almost all materials, including thin metals. 2D or 3D cutting of plates. In the field of sheet metal cutting, efficient cutting can be performed from ultra-thin sheets of microns to thick sheets of tens of millimeters. Laser cutting has incomparable advantages over traditional cutting. It can be said that laser cutting has set off an important process revolution in the sheet metal processing industry.

Working principle: The material to be cut is irradiated with a high power density laser beam, so that the material is quickly heated to the vaporization temperature, and evaporates to form a hole. Sew, complete the cutting of the material – this is laser cutting (LaserCutting). Laser cutting has high efficiency, high energy density and flexibility. Whether in terms of accuracy, speed or efficiency, it is the best choice for the sheet metal cutting industry. The laser can be focused into a very small spot, which can perform micro and precision processing, such as processing of micro slits and micro holes. In addition, it does not need a tool for processing, which belongs to non-contact processing and has no mechanical deformation. Some traditionally difficult to cut or low-quality plates can be easily solved after encountering laser cutting. Especially in the cutting of some carbon steel plates, laser cutting has an unshakable position.

The average person may ask, what can laser cutting do for the general public? Then it has to be mentioned that it plays a vital role in the application field of industrial manufacturing. Laser cutting equipment is the basic equipment necessary for pillar industries such as aerospace, ships, automobiles, and energy equipment. It represents the current world of laser technology and The development direction of its application can not only solve some technical problems in the construction of major projects, but also play a leading role in the formation and development of the country’s emerging laser processing industry in the future.

Laser technology is constantly bringing us surprises and innovating the manufacturing methods that have been constrained for many years in the industry. In recent years, laser processing equipment has been rapidly popularized. In 2017, the sales volume of complete sets of laser cutting equipment in my country exceeded 25,000. The high-power large-format fiber laser cutting machine has a large cutting width and a fast cutting speed that greatly exceeds people’s imagination in the past. It can cut thicker metal sheets and has stable performance, which is an inevitable trend in the development of laser cutting technology. Nowadays, high-power laser cutting machines are very popular in the sheet metal market. With the in-depth application of laser cutting technology, it will further promote the laser cutting technology in the field of sheet metal processing to move towards high precision and high power, which marks the high level of laser cutting. The era of power is coming!

The development of laser cutting is inseparable from the upgrading of laser technology. During the period from 2003 to 2008, gas lasers were still the mainstream of metal cutting, but due to the high cost of millions, only a few large-scale enterprises had the purchasing power. In 2008, Hua-Russian Laser launched the first self-developed large-format solid-state laser cutting machine. The market price was around 580,000 yuan, which was in line with the mainstream market demand and was well received by the sheet metal market. After that, with the rapid development of business volume, Hua-Russian Laser entered the fast lane of development, focusing on enriching the product line of fiber laser cutting machines, with power from 500W to 10000W, and optional formats from 3015 to 12030, and developed high-speed fiber lasers for automatic loading and unloading of flat panels. Automatic production line supporting solutions such as cutting machine, automatic professional pipe cutting machine, automatic uncoiling and leveling laser cutting production line. As a Sino-foreign joint venture high-tech enterprise integrating product research and development, production and sales after ten years, Hua-Russian Laser has won more than 50 national patents and more than 20 national, provincial and municipal scientific and technological achievement awards, and continues to lead the international and domestic laser industry. The innovative development of products has become a global professional laser intelligent equipment manufacturer. At the beginning of 2019, Hua-Russian Laser relied on the self-developed VWJ series high-power fully enclosed exchange type 15000W high-speed fiber laser cutting machine, which has the characteristics of high power, high speed, high efficiency and high precision. With its flexible processing range, powerful Cutting penetration ability and higher processing efficiency have become the representative of the latest productivity in the field of laser cutting.

VWJ series high-power fully-enclosed switching high-speed fiber laser cutting machines compete with each other, why do they stand out? It is a subject worthy of our long-term contemplation. In today’s environment, Hua-Russian laser cutting technology presents two obvious trends, one is high-power large format, and the other is intelligent automation, keeping up with the pace of the times and responding to the call of Made in China 2025, in the wave of laser cutting , Hua-Russian Laser will further improve R&D, production and after-sales service, deepen Sino-Russian technical cooperation, and benefit customers by virtue of the characteristics of high, large, fast, good and provincial, so as to achieve the purpose of reducing costs and increasing efficiency.
