What Are the Classifications of Laser Cutting Machines?

LUKE LASER

There are many types of laser cutting machines. According to the cutting materials, they can be divided into metal laser cutting machines and non-metal laser cutting machines. According to the laser types, they can be divided into fibre laser cutting machines, CO2 laser cutting machines, etc., according to the laser output power classification. It can be divided into high power laser cutting machine, medium power laser cutting machine, low and low power laser cutting machine. Different types of laser cutting machines have different uses, let's take a closer look at it together!

 

1. Classification According to Laser Type

According to the laser type classification of laser cutting machine, it can be divided into three types: fiber laser cutting machine, CO2 gas laser cutting machine, and YAG laser cutting machine that has been eliminated. Now the mainstream type of laser cutting machine on the market is fiber laser cutting machine.

  • The first type: CO2 laser cutting machine

The CO2 laser cutting machine can stably cut carbon steel within 20mm, stainless steel within 10mm, and aluminium alloy within 8mm. The CO2 laser has a wavelength of 10.6um, which is relatively easy to be absorbed by non-metals and can accurately cut non-metal materials such as wood, acrylic, PP, and organic glass. However, the photoelectric conversion rate of the CO2 laser is only about 10%. The CO2 laser cutting machine is equipped with a nozzle for blowing oxygen, compressed air or inert gas N2 at the beam exit to improve the cutting speed and the smoothness of the cut.

Main advantages: high power, general power is between 2000-4000W, can cut full-size stainless steel, carbon steel and other conventional materials within 25 mm, as well as aluminium panels within 4 mm and acrylic panels within 60 mm, wood material panels, and PVC panels, And the speed is very fast when cutting thin plates. In addition, because the CO2 laser outputs a continuous laser, it has the smoothest and best-cutting section effect among the three laser cutting machines when cutting.

Main market positioning: 6-25mm thick plate cutting processing, mainly for large and medium-sized enterprises and some laser cutting processing enterprises that are purely external processing. However, due to the large maintenance loss of their lasers, the large power consumption of the host and other insurmountable factors, in recent years Recently, the market has been in a state of apparent shrinkage due to the huge impact of fibre laser cutting machines.

 

  • The second type: YAG (solid) laser cutting machine

YAG solid-state laser cutting machine has the characteristics of low price and good stability, but the energy efficiency is generally less than 3%. The output power of current products is mostly below 600W. Due to the small output energy, it is mainly used for drilling and spot welding and thin plate Cutting. Its green laser beam can be applied under pulse or continuous wave conditions. It has a short wavelength and good light concentration. It is suitable for precision machining, especially for hole machining under pulse. It can also be used for cutting, welding and lithography, etc. . The wavelength of the YAG solid-state laser cutting machine laser is not easily absorbed by non-metals, so non-metallic materials cannot be cut. What the YAG solid-state laser cutting machine needs to solve is to improve the stability and life of the power supply, that is, to develop a large-capacity, long-life optical pump Excitation light sources, such as the use of semiconductor light pumps, can greatly increase the energy efficiency.

Main advantages: It can cut aluminium plates, copper plates and most non-ferrous metal materials that other laser cutting machines can't cut. The machine purchase price is cheap, the use cost is low, the maintenance is simple, the cost of accessories and maintenance is low, and the machine is easy to operate.

Main market positioning: cutting below 8mm, mainly for self-use small and medium-sized enterprises and most users in sheet metal manufacturing, home appliance manufacturing, kitchenware manufacturing, decoration and decoration, advertising and other industries whose processing requirements are not particularly high, gradually replacing wire cutting, CNC punching, Traditional processing equipment such as water cutting, low-power plasma, etc.

 

Since the fiber laser cutting machine can transmit through the fiber, the degree of flexibility is unprecedentedly improved, the failure point is less, the maintenance is convenient, and the speed is extremely fast. Therefore, the fiber laser cutting machine has great advantages when cutting thin plates within 4mm. It affects its poor quality when cutting thick plates. The wavelength of fiber laser cutting machine is 1.06um, which is not easily absorbed by non-metal, so it cannot cut non-metal materials. The photoelectric conversion rate of fiber laser is as high as 25%, and the advantages of fiber laser in terms of electricity consumption and supporting cooling system are quite obvious.

Main advantages: high photoelectric conversion rate, low power consumption, can cut stainless steel plates and carbon steel plates within 12MM, is the fastest laser cutting machine for cutting thin plates among these three machines, small slits, good spot quality, and can be used for fine Cut

Main market positioning: cutting below 12mm, especially high-precision processing of thin plates, mainly for manufacturers that require extremely high accuracy and efficiency. It is estimated that with the emergence of lasers of 4000W and above, fiber laser cutting machines will eventually replace CO2 high-power lasers Most markets for cutting machines.

 

2. Classified by cutting material type

There are two types of metal laser cutting machine and non-metal laser cutting machine. This is a good distinction. Generally, a metal laser cutting machine is used when metal materials are needed, and a non-metal laser cutting machine is used when cutting non-metal materials.

 

3. Classified by laser output power

According to the laser output power classification, it can be divided into three types: high power laser cutting machine, medium power laser cutting machine, and low and low power laser cutting machine. The laser output power required by different application fields is also different. In the industrial field, high-power fiber laser cutting machines are the main ones, while in the laser engraving field, the medium-power laser engraving and cutting machines are the main ones.

 

4. According to the cutting board size classification

The cutting board format can be divided into two types: standard format and large format, so the laser cutting machine can also be divided into two types: standard format laser cutting machine and large format laser cutting machine. The cutting length of the large-format laser cutting machine in the X-axis direction is more than 8000mm, and the cutting width in the Y-axis direction is more than 2500mm. The cutting area of ​​the standard-format laser cutting machine is generally about 3000mm×1500mm, 4000mm×2000mm.

 

5. Classification according to the geometric shape of the cut sheet

The types of cutting plates can be divided into flat plates and three-dimensional plates. Flat plates are generally cut with a flat laser cutting machine, while three-dimensional plates can be cut with a robot laser cutting machine, a three-dimensional five-axis laser cutting machine, etc.

 

The Choice of Laser Cutting Machine

No matter what kind of laser cutting machine has its own characteristics, choose the right laser cutting machine according to the material you are processing.
