Do you know what types of laser cutting machines are? See this introduction.
A. Optical fiber laser cutting machine
The optical fiber laser cutting machine has great advantages because it can be transmitted through optical fiber, convenient maintenance and fast speed. However, when cutting thin plates within 4mm, due to the influence of solid laser wavelength, the quality of cutting thick plates is poor. The wavelength of the optical fiber laser cutting machine is 1.06um, which is not easy to be absorbed by nonmetals, so it cannot cut nonmetallic materials. The photoelectric conversion rate of fiber laser is more than 25%, which is the advantage of fiber laser in power consumption.
B. CO2 laser cutting machine
CO2 laser cutting machine can stably cut carbon steel within 20mm, and can cut wood, acrylic acid, PP,
Organic glass and other non-metallic materials are of high quality, but the photoelectric conversion rate of CO2 laser is only about 10%.
CO2 laser cutting machine equipped with nozzle can spray oxygen, compressed air, or inject inert gas N2 at the beam outlet to improve cutting speed and smooth cutting.
C. YAG (solid) laser cutting machine
YAG solid laser cutting machine has the characteristics of low price and good stability, but the energy efficiency is generally less than 3%. Due to the small output energy, the current output power of the product is mostly below 600W.
What YAG solid laser cutting machine needs to solve is to improve the stability of power and life, that is, to develop a high-capacity, long-life pump light source. The semiconductor optical pump can greatly improve energy efficiency. It has gradually replaced traditional processing equipment, such as wire cutting, CNC punch, water cutting and low-power plasma.
