Laser cutting machines can be divided into different types according to the laser generator, and different types of equipment have their own specialties for different cutting materials. Mainly fiber laser cutting machines and YAG laser cutting machines.
Comparative analysis of fiber laser cutting machine and YAG laser cutting machine in aluminum cutting.
The comparison of aluminum laser cutting machines is considered from three points: cutting quality, cutting speed and production cost (referring to the cost of service life).
1. Cutting quality
Aluminum profiles are highly reflective materials, so neither fiber laser cutting machines nor YAG laser cutting machines can process thicker aluminum profiles. Aluminum materials are not resistant to high temperatures, and burrs are prone to appear during the cutting process of aluminum materials. Therefore, it is necessary to focus on controlling the process to obtain ideal cutting quality.
2. Cutting speed
The cutting speed also needs to be controlled. If the cutting speed is too fast, it will easily produce burrs. If the cutting speed is too slow, it will cause cracks in the aluminum material, which will affect the cutting quality. Therefore, process control is required. For laser cutting equipment with the same power, the cutting speed of fiber laser cutting machine is higher than that of YAG laser cutting machine.
3. Production cost
The processing cost of laser cutting machine is very low, far lower than other cutting processes, fiber laser cutting machine and YAG laser cutting machine as a comparison, the cost of fiber laser cutting is lower than that of YAG laser cutting machine, which requires regular Replace accessories such as laser lights. From a long-term point of view, the aluminum material will seriously damage the laser of the fiber laser cutting machine, which greatly reduces the life of the laser. From this point of view, the cost of YAG is lower than that of the fiber laser cutting machine.
From the analysis of the above three points, we can see that in the cutting of aluminum, the performance of these two types of laser cutting machines has their own advantages and disadvantages. Aluminum is highly reflective and has low absorption of laser light. Therefore, it is necessary to wear laser protective glasses during processing to protect oneself.
