Technical analysis of laser cutting aluminum materials

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 of these equipments are used to cut aluminum or cut other materials, such as stainless steel and carbon steel. Good performance.

From the experience of laser cutting aluminum materials for many years, the difference between the two is still relatively large, divided into three levels, one is the quality of cutting, the other is the cutting speed, and the third is the production cost (the production cost here is mainly only Equipment life loss).

Cutting quality

Aluminum profiles are highly reflective materials, so neither fiber laser cutting machines nor YAG laser cutting machines can process thicker aluminum. In addition, aluminum materials are not resistant to high temperatures, and burrs are prone to occur during the process of cutting aluminum. Therefore, it is necessary to focus on controlling the process to obtain the desired cutting quality.

2. Cutting speed

The cutting speed also needs to be controlled. Too fast cutting speed is prone to burrs, and too slow cutting speed will cause cracks in the aluminum material, which will affect the cutting quality and thus require process control. In general, for laser cutting equipment of the same power, the cutting speed of the fiber laser cutting machine is higher than that of the YAG laser cutting machine.

3. Production cost

The processing cost of laser cutting machines is very low, far lower than other cutting processes. As a comparison between 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 to replace laser light fittings frequently, but in the long run, aluminum material is fiber laser cutting machine. The damage of the laser is serious, which greatly reduces the life of the laser. From this point of view, YAG is lower than the cost of the fiber laser cutting machine.

In addition, it should be noted that aluminum has high reflectivity and low absorption of laser light, so laser protective glasses need to be worn during processing to protect itself.
