How to Develop the Domestic Laser Cutting Industry?

Apr 08, 2020

Laser cutting is a very important application in laser processing technology. With the decrease of laser cost and the maturity of laser cutting technology, laser cutting machines have been sold in large quantities, accounting for more than 30% of the national laser processing equipment.

Compared with other cutting methods, laser cutting has the characteristics of high speed, high precision, and high adaptability. At the same time, it also has the advantages of the fine cutting seam, small heat affected area, good cutting surface quality, and full automatic control of the cutting process. It can cut carbon steel, stainless steel, alloy steel, high anti-metal materials, leather, quartz, ceramics, glass, composite materials, etc. At present, laser cutting has been widely used in plate processing, automobile and locomotive manufacturing, aviation, chemical industry, light industry, electrical and electronic, petroleum and metallurgy, and other industrial sectors. In recent years, laser cutting technology has developed rapidly, with an annual growth rate of 15% to 20% in the world. Laser cutting technology has become a new tool for industrial processing.

China's commercial laser cutting equipment began around 2000. Before that, all laser cutting machines had to be imported at a price of millions. At that time, CO2 laser cutting dominated the pattern. Since 2009, there have been domestic fiber lasers, and several leading machine integrators have begun to "taste the fresh". The technological breakthrough and development of domestic high-power fiber lasers have driven the price of laser cutting equipment down, and the rapid development of fiber laser cutting has replaced the leading position of CO2 laser cutting in only five years.

At present, more than 10000 sets of CNC laser cutting equipment at all power levels are shipped in China every year. With the rapid development of the equipment manufacturing industry, China's CNC laser cutting equipment has entered a rapid growth period, with an annual growth rate of more than 30%. With the rapid development of our national economy, many traditional industries need to be transformed, many sheet metal processing areas need to be developed, and many industrial cities need to establish laser processing centers.

Currently, the development trend and characteristics of laser cutting technology are as follows: first, it advances to high-speed and high-precision laser cutting machine; second, it is a large laser cutting equipment with higher power and large size; third, it is a three-dimensional multi-axis flexible multi-functional laser cutting machine. In order to meet the needs of three-dimensional workpiece cutting in automobile, aviation, and other industries, various kinds of 5-axis or 6-axis three-dimensional laser cutting machines have been developed, with high processing speed and precision, and the processing error within 6.2m is only within 0.1mm. At present, the three-dimensional laser cutting machine is developing in the direction of high efficiency, high precision, multi-function, and high adaptability, and its application range will be larger and larger.

With the further promotion of "made in China 2025" development strategy, laser intelligent manufacturing has been paid more and more attention. With the development of technology, the requirements of laser cutting are higher and higher, faster speed, higher precision, and lower maintenance cost. At the same time, laser cutting also tends to be more high-power, more automatic processing development. At the same time, laser cutting faces many problems, such as nonstandard products, too much homogeneous competition, and no obvious difference in the application market.
