According to the different laser generators, currently there are three types of laser cutting machines on the market. CO2 laser cutting machines, solid (YAG) laser cutting machines, and fiber laser cutting machines. The following briefly introduces the characteristics of laser cutting machines. The characteristics of fiber laser cutting machine.

 

The characteritics of fiber laser cutting machine

Fiber laser cutting machine, because it can transmit through fiber, has unprecedente flexibility, fewer failure points, convenient maintenance, and fast speed. Therefore, fiber cutting machine has great advantages when cutting thin plates within 4mm. But it is affected by the wavelength of solid laser. It has poor quality when cutting thick plates. The wavelength of the fiber laser cutting machine is 1.06um. Which is not easily absorbed by non-metals, so it cannot cut non-metal materials. Fiber laser has a photoelectric conversion rate of more than 25%. The advantages of fiber lasers in terms of electricity consumption and supporting cooling systems are quite obvious. According to international safety standards, laser hazards are classified into four levels. Fiber lasers are the most damaging because of the short wavelength to the human body due to the large eye damage. For safety reasons, fiber laser processing requires a completely enclosed environment.

Main advantages

High photoelectric conversion rate. Low power consumption, can cut stainless steel plates, carbon steel plates within 12MM. The fastest laser cutting machine of these three machines, thin slits, good light spot quality, can be used for fine Cutting.

Main disadvantages and disadvantages

At present, most of the core key technologies of fiber lasers are in the hands of one or two manufacturers in Europe, America and other countries. So most of the machines are expensive, most of the machines are more than 1.5 million. And the low-power ones are basically in About 500,000 yuan. Because the fiber slit is very thin and the gas consumption is huge (especially when nitrogen cutting). And it is difficult or impossible for the fiber laser cutting machine to cut highly reflective materials such as aluminum and copper plates. And the speed when cutting thick plates very slow.

Main market positioning

Cutting below 12mm, especially for high-precision processing of thin plates, mainly aimed at manufacturers with high requirements on accuracy and efficiency. It is estimated that with the emergence of 5000W and above lasers, fiber laser cutting machines will eventually replace CO2 high-power lasers. Cutting machines in most markets.
