The Characteristics of the CO2 Laser Cutting Machine

High quality CO2 laser cutting machines uses a mixture of gases to generate the laser beam. The high voltage required in the resonator for the excitation of gas is generated by wear-free semiconductor modules, which are small, efficient and reliable. CO2 laser cutting technology is suitable for cutting different materials, plates, wood, acrylic, glass, paper, textiles, plastics, leather and stone.

CO2 laser cutting machines have a high production all sheet thicknesses up to 30mm and tube parts. When the cutting process is done with O2, speed is almost same as in fiber, for thicknesses greater than 6 mm.

Characteristics of the Fiber Laser Cutting


Fiber laser cutting machines are the latest development in laser cutting. The laser beam is generated in an active fiber and is guided into the cutting head of the machine using a transport fiber, through diodes and fiber cables.

Fiber laser cutting machines can be smaller than the CO2 laser cutting machines and get twice the power with the same power supply. Fiber laser cutting is suitable for the treatment of fine sheet, thickness average up to 12mm and non-ferrous metals, such as copper and brass. The access to the machine is limited by security, since laser reflections are highly harmful to the view. The focal diameter is very small, a hundred times more intensity than with CO2.

In terms of the thickness of sheet metal that can cut, CO2 laser cutting machine can cut down to 30 mm thick, while the single fiber laser cutting machine can cut thin and medium up to 20 mm. thick sheet

Regarding access to the cutting machine, since wavelength of the fiber laser is 1.064 microns and the CO2 laser is 10.6 micrometers, the fiber laser is ten times lower, therefore need much greater security as reflections laser are harmful for the eyes. On the contrary, the CO2 laser cutting machine has exceptional access to the machine without being detrimental to the view.

Because the fiber laser cutting machine is more efficient energy, does not require any gas of resonator, the costs are lower than with CO2 laser cutting. Per unit of power flowing through a system of cutting CO2 laser, approximately are used between 8 and 10%, while with the fiber laser cutting can be expected approximately 25-30%.

CO2 laser cutting machine as used mirrors to make the beam reach the lens, and these mirrors must be at a certain distance, requires more space for the design of the machine with the fiber laser cutting machine its compact design requires little space.

In terms of the lenses used, CO2 laser cutting requires two lenses should change depending on the material and thickness, and its life cycle is approximately 1000 hours. Fiber laser cutting, uses a single lens with a life cycle of approximately between 4,000 and 5,000 hours
