After decades of development of laser cutting technology, the application scope of laser in different fields is gradually deepening. In order to improve the processing method, more and more laser cutting machines are used in the traditional processing and manufacturing industry. It has also become an important part of advanced manufacturing technology. Its characteristics of high accuracy, high processing efficiency and low pollution make it widely used in the field of metal cutting. Metal laser cutting machine is a laser cutting equipment specially used for cutting and processing metal materials. Metal laser cutting machine uses high-power density laser beam to scan the surface of materials and heat the materials to thousands to tens of thousands of degrees Celsius in a very short time, Melt or gasify the material, and then blow the melted or gasified material away from the cutting seam with high-pressure gas to achieve the purpose of cutting the material.
Several key technologies of metal laser cutting machine are the integrated technology of light, machine and electricity The parameters of laser beam, the performance and accuracy of machine and CNC system directly affect the efficiency and quality of laser cutting Especially for parts with high cutting accuracy or large thickness, it is necessary to master key technologies in order to use them more efficiently,
The focus control system of metal laser cutting machine is the future research status and development trend at home and abroad. Many metal laser cutting machine manufacturers are also very optimistic about the development prospect of metal laser cutting machine. The focus control system is a vital part of metal laser cutting machine. It is directly related to the accuracy and stability of laser focus position, which determines the cutting quality of metal workpiece. Therefore, designing a focus control system is of great significance for metal laser cutting machine, and it is also one of the hotspots of future development. In the future, we should not only improve the proprietary technology of metal laser cutting machine, but also improve the research of metal laser cutting technology.
