As of today, laser cutting machine is still the most common cutting method in the industry. Among them, the laser cutting machine is divided into fiber laser cutting machine and CO2 laser cutting machine. According to different materials and products, the selected laser cutting machine is also different.
The laser wavelengths of 1.06 μ m and 10.6 μ m generated by fiber laser and CO2 laser are both infrared light and can be absorbed by materials, so they are only used for industrial material processing. Fiber laser cannot cut non-metal, including wood, plastic, leather, cotton and linen fabrics. If the material to be processed is just non-metallic, the fiber laser can only be rejected and the CO2 laser cannot be used. Including brass, red copper, etc., CO2 laser cannot cut. As for CO2 laser, copper is a highly reflective material, and the laser is basically completely reflected without being absorbed. The light is reflected back to the laser, causing harm.
Laser cutting machine prototype
Colleagues, we can comprehensively evaluate the laser and equipment in terms of cutting speed, cutting efficiency and section quality.
Fiber laser cutting thin plate has its advantages, especially when the thickness is less than 3mm. Compared with CO2 laser, the maximum cutting speed ratio can reach 4:1; And 6mm is the critical thickness of the two laser advantages exchange. Fiber laser has no advantage over cutting plates with thickness greater than 6mm, and CO2 gradually appears with the increase of thickness, but it is not significant. In general, fiber laser has advantages in cutting speed.
