Laser Cutting Machine To Bring A New Era

- Jun 27, 2018 -

According to international safety standards, laser damage rating of 4, fiber laser due to short wavelength on the human body because of the eye damage, is the most dangerous level, for security reasons, fiber laser processing needs a fully enclosed environment.

Laser cutting machine

YAG solid laser cutting machine with low price, good stability characteristics, but the energy efficiency is low <3%, the current output power of products are mostly below 600W, due to the output energy is small, mainly for drilling and spot welding and sheet cutting. Fiber laser cutting machine as a new laser technology, the popularity of far less than CO2 laser cutting machine. CO2 laser has a wavelength of 10.6 um, which is easy to be absorbed by nonmetallic materials. It can cut high quality non-metallic materials such as wood, acrylic, PP and plexiglass, but the photoelectric conversion rate of CO2 laser is only about 10%. The CO2 laser cutting machine is equipped with nozzles for blowing oxygen, compressed air or inert gas N2 at the exit of the beam to increase the cutting speed and the smoothness of the incision. Fiber laser photoelectric conversion rate of up to 25% or more, in the electricity consumption, supporting the cooling system, etc. The advantages of fiber laser is quite obvious. Its green laser beam can be used in the case of pulse or continuous wave, with a short wavelength, good condenser for precision machining, especially in the pulse under the hole processing is most effective, can also be used for cutting, welding and lithography.The YAG solid laser cutting machine laser wavelength is not easy to be non-metallic absorption, it can not cut non-metallic materials, and YAG solid laser cutting machine needs to be addressed is to improve the stability and life of power, that is, to develop large-capacity, long- exciting light sources, such as the use of semiconductor light pump can make energy efficiency greatly increased. According to international safety standards, laser hazard grade 4, CO2 laser is the least harm level.

CO2 laser cutting machine, can be stable within 20mm within the carbon steel, 10mm within the stainless steel, 8mm below the aluminum alloy.

Fiber laser cutting machine because it can be transmitted through the optical fiber, the degree of flexibility to improve the unprecedented, less trouble, easy maintenance, fast speed, so cutting 4mm within the thin plate when the fiber cutting machine has a great advantage, but by the solid laser wavelength,the impact of it in the cutting plate when the quality is poor. In the field of laser cutting machine, the current show YAG solid laser cutting machine, CO2 laser cutting machine full feet, fiber laser cutting machine come from behind the situation. With the rapid development of the laser industry, the relevant laser technology and laser products are becoming more mature. Fiber laser laser cutting machine wavelength of 1.06um, not easy to be non-metallic absorption, it can not cut non-metallic materials. In order to improve the stability and longevity of power supply, for CO2 gas laser to solve the high power laser discharge stability.
