The application of laser cutting technology not only improves processing efficiency but also enhances product precision. Laser cutting is a widely used technology. In the manufacturing field, approximately 73% of processing operations are completed using laser cutting technology.
Compared to traditional cutting methods, laser cutting technology offers advantages such as high precision, strong adaptability, low noise, and excellent cutting quality, leading to its widespread application. Furthermore, for complex machining operations that previously relied on large molds, laser cutting eliminates the need for molds while maintaining consistent cutting quality. This reduces production costs and increases production efficiency. Consequently, laser cutting technology is widely used in the automotive, aerospace, and light industries. In recent years, with the development of my country's processing industry, the application of laser cutting technology has experienced rapid growth.
With the widespread application of machining and cutting technologies, the development of laser cutting machines has accelerated further. The advancement of laser cutting technology allows for more sophisticated applications. Currently, laser cutting technology is developing towards high-speed, high-precision cutting. However, China's machining and cutting technologies still lag behind.
In response to this situation, my country's current machining and cutting technology is gradually developing towards high speed and high precision. Currently, the beam mode of high-power lasers has been improved, and the application of microcomputers has made it possible to produce high-precision, high-speed machining and cutting equipment. At present, the laser cutting technology used in my country has speeds exceeding 20 m/min, with two-axis movement speeds reaching 250 m/min, and accelerations reaching approximately 10G during operation. On a 1 mm thick plate, approximately 500 holes of about 10 mm can be cut per minute.
In the application of laser cutting technology, it is found that these holes are of similar size. This indicates that laser cutting technology is actually developing towards high speed and high precision in practical applications. When laser cutting technology is applied to thick plate cutting and large-size workpiece cutting, it can be observed that the power of the laser cutting equipment used in actual operation is gradually increasing, and laser cutting is also developing from cutting thin plates for light industry to cutting thick plates for heavy industry.
A high-power 20KW laser can cut carbon steel plates up to 100mm thick. As cutting technology continues to improve, my country has been experimenting with this technology, and 6KW lasers are gradually being applied to cutting 25mm thick carbon steel plates. Moreover, the project is already operational. Furthermore, the range of workpiece sizes used in laser cutting technology is increasing.
Actual cutting processes reveal that laser cutting technology is increasingly focused on thicker plates and larger dimensions, driving the design of laser cutting equipment in this direction and further improving industrial processing technology. Following China's accession to the World Trade Organization, frequent international exchanges have propelled various industries into international competition. In this process, industries such as automotive and aerospace require the continuous application of laser cutting technology. Furthermore, China has also adopted three-dimensional six-axis laser cutting technology.
In processing operations, the application of 3D laser cutting machines in practical operations helps laser cutting technology develop towards greater precision, and the economic development of 3D laser cutting promotes the maturity of processing technology. As a processing technology, the development of laser cutting technology towards automation and unmanned operation is both necessary and urgent.
Meanwhile, the application of computer network technology has made automated and unmanned laser cutting technology possible. Currently, many laser cutting machines of this type have been produced abroad, and the market demand for this technology is increasing, gradually leading to the automation and unmanned operation of laser cutting technology.
