From the perspective of cost and investment, the widely used aluminum laser cutting equipment is fiber laser cutting machine and YAG laser cutting machine. Both devices cut aluminum material or cut other materials, such as stainless steel. Carbon steel, etc. have a good performance.
From the experience of laser cutting aluminum materials over the years, the difference between the two is still relatively large, and it is divided into three levels. First, the quality of cutting, the second is the cutting speed, and the third is the production cost (the production cost here is mainly only Equipment life loss).
1. Cutting quality Aluminium profiles are highly reflective materials, so neither the fiber laser cutting machine nor the YAG laser cutting machine can process thick aluminum. In addition, the aluminum material is not resistant to high temperatures, and burrs are easily generated during the cutting of the aluminum material. Therefore, it is necessary to control the process and obtain the desired cutting quality.
2. Cutting speed Cutting speed also needs to be controlled, too fast cutting speed is easy to produce burrs, too slow cutting speed will cause aluminum material cracks, affect the cutting quality, and therefore need process control. In general, with the same power laser cutting equipment, the cutting speed of the fiber laser cutting machine is higher than that of the YAG laser cutting machine.
3. Production Costs The laser cutting machine's processing costs are very low, much lower than other cutting processes. Compared with fiber laser cutting machine and YAG laser cutting machine, the cost of fiber laser cutting is lower than that of YAG laser cutting machine. The latter needs frequent replacement of laser lamp and light fittings. But in the long run, aluminum material is used for fiber laser cutting machine. The damage of the laser is relatively serious and the life of the laser is greatly reduced. From this point of view, YAG is lower in cost than the fiber laser cutting machine.
In addition, it should be noted that aluminum materials have high reflectivity and low absorption of laser light. Therefore, laser protective glasses must be worn during the process to protect their own safety.
