The Difference Between CO2 Laser Cutting Machine & Fiber Laser Cutting Machine

May 24, 2022

From the perspective of the current production and processing application fields and current application requirements, laser cutting and laser marking are undoubtedly a high-power, format, high-power, intelligent laser processing at present choice.

So what are the differences between the processing methods of CO2 laser cutting machine and fiber laser cutting machine?

As the mainstream traditional laser cutting machine and marking machine, the effect that can be done by different lasers is also different. Generally, non-metal laser cutting mainly uses CO2 laser. The main light energy that CO2 laser cutting machine can generate is suitable for non-metal absorption and can have high quality cutting requirements. CO2 laser cutting machine is mainly used in laser cutting of non-metallic materials such as acrylic sheet, PP and plexiglass. The fiber laser marking machine is mainly used for laser marking and cutting on metal materials.

From a professional point of view, the wavelength difference between CO2 laser cutting machine and fiber laser is not an order of magnitude. The fiber laser cutting machine mainly adopts the optical fiber transmission. In the process of processing, the processing degree of processing flexibility can be gradually increased. The photoelectric conversion rate of fiber laser is as high as 25% in the process of use, while the photoelectric conversion rate of CO2 laser is only about 10%. Fiber lasers have obvious advantages in electricity consumption.

CO2 lasers are considered to be the least hazardous in terms of international safety standards. The fiber laser is relatively harmful to the human body, especially the eyes, due to its relatively short wave, and it belongs to the most harmful level. For safety reasons, fiber laser processing requires a fully enclosed environment.
