What are the advantages and disadvantages of CO2 cutter and YAG cutter

The advantages and disadvantages of CO2 cutter and YAG cutter are described as follows:

1. CO2 laser cutting machine.

Advantages: High power, able to cut 25 mm stainless steel, carbon steel and other materials. The cutting thickness of acrylic, woody materials, PVC and other materials of non-metallic materials can reach 60 mm.

It can cut 4 mm of highly reflective material aluminum plate. The CO2 laser cutting machine uses a continuous laser, and the cutting surface is smooth and cutting.

Disadvantages: high cost, high-power CO2 laser cutting machine has reached more than 2 million, and the cost of maintenance is high, the photoelectric conversion rate in the use process is only 10%, and the energy consumption is high. It is inconvenient to maintain, and the operation requirements are high.

2. YAG laser cutting machine.

Advantages: Able to cut highly reflective materials, such as aluminum, copper, and many non-ferrous metal materials that cannot be cut by laser cutting machines. All manufacturers have mastered the key technology of YAG laser cutting machine, and the cost of procurement is low, the operation is simple, and the maintenance is simple.

Disadvantages: It can only cut thin sheet materials below 8 mm, the cutting speed is slow, and the efficiency is relatively low.

YAG laser cutting machine.

Advantages: YAG solid-state laser output wavelength is short, coupling with metal is high, beneficial to be absorbed by the metal surface, carbon steel, stainless steel including copper, aluminum and other highly reflective non-ferrous metals have good light absorption, and YAG laser is small in size, equipment occupies a small area, low energy consumption, low investment cost, suitable for small and medium-sized enterprises.

Disadvantages: The conversion efficiency of YAG solid-state laser is low, only 1 3%; There is an internal temperature gradient in the working process of the YAG laser bar, which will cause thermal stress and thermal lensing effect, which limits the further improvement of the average power and beam quality of the YAG laser. The cost per watt of output power of YAG lasers is more expensive than that of CO2 lasers and fiber lasers.

Advantages: Because the input laser wavelength of CO2 laser is micron, the wavelength is long, the coupling with non-metallic materials is high, and it is easy to be absorbed by non-metallic appearance, so small and medium-power CO2 lasers are mainly used in non-metallic material processing industries, and high-power CO2 lasers are mainly used in metal material processing industries.

There are more CO2 applications and fewer YAG applications. The process is not as mature as CO2.

CO2 is generally used for non-metallic materials, and YAG is generally used for metallic materials.

Compared with the high-power CO2 laser cutting machine, the outstanding advantages of the YAG laser cutting machine are that the equipment cost of the YAG laser cutting machine is low, the power consumption is low, the cutting gap is small, the processing precision accuracy is high, and the cost performance is extremely high. The CO2 metal laser cutting machine has high cost, expensive equipment, and extremely high cost of use, and it is difficult to effectively control the domestic system in terms of stability.

YAG laser cutting machine is an automatic laser processing equipment manufactured by integrating laser technology and numerical control technology, which has the characteristics of high efficiency, low cost, stability, safety and more precision. YAG laser cutting machine is mainly used for non-contact cutting and punching of various metal plates and metal pipes, especially suitable for the cutting and processing of stainless steel plates, iron plates, thin aluminum plates, thin copper plates, silicon wafers, ceramic sheets, diamonds and other materials.

Stainless steel, carbon steel, alloy steel, silicon steel, spring steel, aluminum, aluminum alloy, galvanized sheet, aluminum-zinc plate, pickled board, copper, silver, gold, monocrystalline silicon, polysilicon and other titanium and other metal plates and pipe cutting.
