Laser cutting machine features: fiber laser compared with CO2 laser

Introduction: before using CO2 laser, optical path adjustment is required. The optical path will directly affect the cutting effect of workpiece, so manual adjustment of optical path and regular maintenance are required.

1. Operation requirements and maintenance

Before using CO2 laser, optical path adjustment is required. The optical path will directly affect the cutting effect of workpiece, so manual adjustment of optical path and regular maintenance are required. YAG solid state laser has obvious thermal lensing effect and needs constant maintenance. Optical fiber laser fiber transmission, no adjustment, no maintenance, high stability, easy to operate.

2. Cutting speed and effect

The cutting speed of fiber laser is 2-3 times that of CO2 laser with the same power. It has prominent advantages in the cutting process of metal plates. It has excellent performance in the other two laser cutting machines with good cutting quality, small gaps and neat edges.

3. Material applicability and application industry

CO2 laser is more widely applicable to materials, while fiber laser is more applicable to metal materials including aluminum, copper and other high reflection materials, which is more in line with the processing requirements of sheet metal manufacturing, 3C home appliance industry and new energy industry.

4. Energy consumption and comprehensive cost

Fiber laser photoelectric conversion rate of more than 30%, with power CO2 laser cutting machine photoelectric conversion rate of about 10% ~ 15%, solid laser photoelectric conversion rate of 3%. The power consumption of fiber laser is only 20-30% of that of CO2 laser with the same power, and the comprehensive cost is lower. Through the comparison, it can be seen that the fiber laser cutting machine in the same conditions of higher efficiency, better cutting effect, maintenance free, but in the purchase cost is slightly higher, large and medium-sized enterprises can give priority to optical fiber equipment.

 

How can CO2 laser cutter find a new dawn?

As we all know, the rapid development of fiber laser in recent years is constantly eroding the market share of  CO2 laser cutter.   In the past few years, when fiber laser, disc laser, semiconductor laser and other products began to be popular.So CO2 laser cutting machine seems to have been a huge impact.

So, how can we find a new market dawn for the CO2 laser’s ancient laser technology?

It is undeniable that the development of fiber laser does have a great impact on some applications of CO2 laser engraver. But it is also undeniable that there are still many applications in the market that other types of lasers can not be competent, can only use CO2 laser cutters, such as some non-metallic processing application. At the same time, CO2 laser is also opening up unprecedented new applications.

The unique wavelength of CO2 laser cutter makes it the best choice for processing some non-metallic materials. One of the simplest applications is the coding of information such as the date of production on a beverage bottle.

In the past, this information was usually printed on a beverage bottle with ink. This method is neither environmentally friendly nor cost-effective. Now, more and more CO2 lasers are used to encode this information. This way is clean and environmentally friendly without ink consumption. Fiber lasers are not equal to this task.

    In addition to some traditional applications on the market, CO2 laser cutting machine is also constantly developing some unprecedented new applications.

Some new applications of CO2 laser cutting machine. For example, the manufacture of fiber lasers. Now that CO2 lasers can participate in the manufacture of fiber lasers. It can also benefit from the growth of the fiber laser market. High-power fiber lasers require extremely strict purity of fiber. The traditional flame processing of fiber may bring some impurities into the fiber. Therefore, many customers use CO2 laser to process parts of fiber lasers.

Another way is to produce extremely ultraviolet light. In the process of semiconductor fabrication.  However, with the development of Moore’s law. Circuits on the chip are more and and more , and the precision requirment is higher and higher. This requires a laser with a wavelength of about 10 nm to complete this task.

At present, laser cutting machine has many new applications. If you need  laser engraver, please feel free to contact us.There are multipoint positioning laser cutting machine and  large scale visual scan machine ,etc.
