TopTech Laser Cutting Tips III
--CO2 Laser CNC Cutting Machine


Laser cutting is a non-touching processing way to avoid machine pressure and have perfect working process on the surface. The super control system, Eckelmann EXC880, makes not only precision processing, but also sharp angle, small hole, and more complicated geometric figure cutting which cant be done by traditional cutting die process. With advanced IBE nesting system inside Eckelmann EXC880 which adopt on TopTech laser cutting machines, it totally reduce human cost and material lost.

After more than 20 years development of laser technology updating and working process all over the world, laser cutting technology and laser cutting machines had been accepted and familiar with vast plates processors about high effective, high precision, perfect cutting finish of laser cutting process.

According to different types of laser sources, right now there are 3 main types of laser cutting machines: CO2 laser cutting machine, YAG laser cutting machine (also called solid laser cutting machine), and fiber laser cutting machine.

TopTech would like to share the differences, advantages of these 3 types laser cutting methods.


III. CO2 laser cutting machine

 TopTech Laser Cutting Tips III

CO2 laser cutting machine can cut within 20mm carbon steel stably, within 10mm stainless steel, within 8mm aluminium alloy. The wave length of CO2 laser tube is 10.6um, which is easy absorbed by non-metal materials. It can cut wood, acrylic, PP, organic glass and other non-metal materials with high quality.CO2 lasers light-electric percent conversion is only about 10%.


There is a nozzle at CO2 laser cutting machine's light exit for injecting O2, compressed air or inert gas N2 to improve cutting speed and the cutting finish quality. To improve CO2 laser source stability and life time, the key point is to solve the issue of laser source releasing electric stability. CO2 laser belongs to lest damage on human body based on International safety standard.


ADVANTAGE of CO2 laser cutting machine:

CO2 laser power is very big. Normally the output power is between 2000-4000W, which can cut with in 25mm stainless steel, carbon steel and normal materials, and it can cut within 4mm Aluminuim plates and within 60mm acrylic boards, wood materials, PVC.


ATTENTION on CO2 laser cutting machine:

The key technology had held in USA manufacturers. Some Chinese manufacturers had got the same level technology of low CO2 laser power source. But CO2 laser cutting machine maintenance fee is very expensive and very difficult, the requires of operators is very high.

From 6-25mm middle thick plates cutting requires, CO2 laser cutting machine can be good choice, but also need to consider about the maintenance cost. With mature technology of fiber laser cutting machine, such as TopTech Fiber II laser CNC cutting machine, CO2 laser cutting machine will be taken over by fiber laser cutting machine in the future.
