Table Of Contents

1. Better beam quality

Compared with CO2 laser cutting machine, fiber laser cutting machine has better beam quality and smaller focus spot, which makes the cutting line finer and can achieve better processing.

2. Faster cutting speed and higher processing efficiency

Compared with the CO2 laser cutting machine, the cutting speed and efficiency of the optical fiber laser cutting machine are twice that of the CO2 laser cutting machine with the same power.

3. Better stability of equipment

The fiber laser adopts semiconductor modularization and redundancy design, and there is no optical lens in the resonant cavity, so no starting time is required.

Compared with CO2 laser, fiber laser has the advantages of no adjustment, no maintenance, and high stability, which is also incomparable with other traditional lasers.

A good fiber laser has stable performance, and the service life of key components can reach 100000 hours.

4. Higher photoelectric conversion efficiency

The photoelectric conversion rate of the optical fiber laser cutting machine is about 30%, which is 3 times higher than that of the carbon dioxide laser cutting machine, saving energy and environmental protection, and reducing production costs.

5. Lower use and maintenance costs

The power consumption of an optical fiber laser cutting machine is only 20~30% of that of a CO2 laser cutting machine, and the use cost is lower than that of a CO2 laser cutting machine.

At the same time, the optical fiber laser cutting machine does not need laser working gas, optical fiber transmission, and reflective lenses, saving a large part of maintenance costs.

The fiber laser only needs to provide a constant temperature and humidity environment.

Clean distilled water or deionized water can cool the laser and provide stable power output.

The maintenance is simple.

6. Simpler light path and more convenient operation

Compared with the CO2 laser cutting machine, the whole optical path of the optical fiber laser cutting machine is transmitted by optical fiber, and does not require complex light guide systems such as mirrors.

The optical path is simple, the structure is stable, and the maintenance is convenient.
