Cutting speed and effect of fiber laser cutting machine

Laser cutting machines are now mainly divided into CO2 lasers, YAG solid-state lasers and fiber laser cutting machines. These three laser cutting machines have their own characteristics in production. Below, we will compare three common lasers from several aspects. The characteristics of the cutting machine.

1. Operation requirements and maintenance

The CO2 laser needs to adjust the optical path before use. The condition of the optical path will directly affect the cutting effect of the workpiece, so manual adjustment of the optical path and regular maintenance are required; the YAG solid-state laser has obvious thermal lens effect and requires frequent maintenance; fiber laser fiber transmission, adjustment-free , Maintenance-free, high stability, easy operation.

2. Cutting speed and effect

The cutting speed of fiber laser is 2-3 times that of CO2 laser of the same power. The advantage is particularly prominent in the cutting process of sheet metal. It has excellent performance in the other two laser cutting machines. The cutting quality is good, the gap is small, and the edges are neat. .

3. Material suitability and application industry

CO2 lasers are more widely applicable to materials, while fiber lasers are more applicable to metal materials including high-reflective materials such as aluminum and copper, which are more in line with the processing requirements of sheet metal manufacturing, 3C household appliances industry, and new energy industry.

4. Energy consumption level and overall cost

The photoelectric conversion rate of fiber laser is over 30%, the photoelectric conversion rate of the same power CO2 laser cutting machine is about 10%-15%, and the photoelectric conversion rate of solid laser is 3%. The power consumption of the fiber laser is only 20-30% of the same power CO2 laser, and the overall cost is lower.

Through comparison, it can be seen that the fiber laser cutting machine has higher working efficiency under the same conditions, better cutting effect, and maintenance-free, but the purchase cost is slightly higher, and large and medium-sized enterprises can give priority to fiber optic equipment.
