As we all know, metal laser CNC machine tools are metal CNC machine tools that use laser technology to cut metal. The emergence of the CNC metal laser cutting machines can be described as a technological revolution in the field of metal processing. The laser metal cutting process has the characteristics of fast speed, good accuracy, high flexibility, and a short production cycle, which can bring high benefits to manufacturers. Therefore, the metal laser cutting machine is a good choice for metal processing manufacturers.At present, there are two mainstream CNC metal cutting machines using laser technology on the market. They are CO2 laser cutting machines and fiber laser cutting machines. Although the CO2 laser cutting machine can realize CNC metal cutting, its processing efficiency is relatively low. In contrast, when performing CNC metal cutting, such as CNC steel cutting or CNC aluminum cutting, the efficiency of the fiber CNC metal laser cutting machine is 200% higher than that of the CO2 laser cutting machine. In addition, the optical fiber CNC metal laser cutting machine can cut more types, thicker and larger metal materials. Therefore, the CNC laser metal cutting machine mentioned in this article mainly refers to the optical fiber CNC metal laser cutting machine.
