The types of laser cutting machines include CO2 laser cutting machine, YAG laser cutting machine and optical fiber laser cutting machine. The advantages and disadvantages of these three machines are listed below.
First used for CO2 laser cutting machine: it is the leader in the field of thick plate cutting, and has unique advantages in the field of thick plate cutting.
Advantages: It matures earlier than fiber laser. It can effectively complete the perfect cutting of thick plates. It can cut 20mm above stainless steel and 10mm above carbon steel. Most commonly used for cutting hull.
Disadvantages: The price is high, and the unit price can reach 1.6 million yuan. Moreover, the use cost is very high. Taking 4KW as an example, the annual maintenance cost is about 400000 yuan.

2、 YAG laser cutting machine: widely used in early cutting machine. Now, it is rare in the market. Laser generated by xenon tube.
Advantages: high laser intensity, commonly used in cutting plate, low price. It can cut brass, aluminum and other highly reflective materials
Disadvantages: large power consumption and many consumables. Low beam quality and average cutting effect. Regular dimming and maintenance are required.
Third, fiber laser cutting machine: it has developed rapidly in recent years. It is becoming more and more popular in the metal processing industry. It is gradually replacing plasma cutting machines, CO2 laser cutting machines, YAG laser cutting machines and shearing machines.
Advantages: low power consumption, no gas consumption, no adjustment, no maintenance, high stability, good output beam quality, and faster cutting speed. In addition, there is no need to maintain the external optical path. The whole workpiece has good cutting consistency, less consumables, small volume, light weight, movable working position, small floor area, and long service life.
Disadvantages: slow cutting of thick metal plates. And it can not cut brass, copper, aluminum and other high reflective materials for a long time.
