Laser cutting machine SUPER PK! Fiber, CO2, YAG, which one do you choose?

Post by perfectlaserChina » Wed Aug 08, 2018 5:50 am

The reason why the fiber laser cutting machine can quickly grasp a large share in the market and gradually replace the traditional cutting process is due to its unique advantages in all aspects, then what is its excellence? Here, we will compare the CO2 laser cutting machine with the YAG laser cutting machine in detailed.

From the perspective of processing
On the one hand, the CO2 laser cutting machine has a wide range of cutting, which can cut metal plates and highly reflective materials such as aluminum plates. For non-metallic materials such as acrylic, wood materials, and PVC, the CO2 laser cutting machine also can reach a good cutting effect. Besides, CO2 laser cutting machine adopts continuous laser, the cutting surface is smooth, and cutting quality is good.
On the other hand, the CO2 laser cutting machine has a narrow cutting seam, but it is very slow when processing thick plates. In the processing of thin metal plates, the cutting speed for fiber laser cutting machine is 2-3 times higher than that of CO2 with the same power, and the cutting edge is much more smooth. In addition, the beam divergence for CO2 laser cutting machine is large and it is not suitable for large-format processing.
From the perspective of cost
The maintenance cost of the CO2 laser cutting machine is higher than fiber laser cutting machine. Not only the mirrors are expensive, but also the life of the turbine bearing is only 8,000 hours, and the replacement cost is around USD13000 per pair. At the same time, CO2 laser cutting machine need gas consumption, and the photoelectric conversion rate is only 8% -10%. Fiber laser cutting machine has no consumable when processing, and its photoelectric conversion rate can reach to 30%, more energy saving.
From the perspective of maintenance
The laser structure of CO2 laser cutting machine is complex, it is inconvenient to maintain, and the operation requirements are high. The maintenance of fiber laser cutting machine is relatively simple, and it can be used in harsh working environments. It has high tolerance to dust, shock, impact, humidity and temperature. degree.

1). From the perspective of processing
YAG laser cutting machine is low in cost and can cut high reflective materials, such as aluminum, copper and other non-ferrous metal materials that cannot be cut by fiber laser cutting machines. However, the power for YAG laser cutting machine is very low, and can only cut thin metal plate below 8 mm. Compared with fiber laser cutting machines, the cutting speed is much slower than that of fiber laser cutting machine, and the efficiency is relatively low. Fiber laser technology can achieve very high power in a very small package, so it can save much space.
2). From the perspective of cost
YAG laser is a kind of laser that has been developed for several decades. The technology is mature, so YAG laser cutting machine is relatively cheap. But with the popularity of fiber lasers, this advantage is getting weaker and weaker. In addition, The power consumption of YAG laser cutting machine during processing is large.
3). From the perspective of maintenance
Since there is no optical lens in the cavity of the fiber laser, it has the advantages of no adjustment, no maintenance, and high stability, so the maintenance and replacement of the device is relatively simple. This is unmatched by traditional YAG lasers.
To sum up, the advantage of fiber laser cutting machine is more obvious. However, these three types of laser cutting machines have their own uniqueness characteristics. You can choose the best one according to your actual cutting needs and budget.
