CO2 laser cutting machine uses an infrared laser with a wavelength of 10.6μm, which has good absorption in many materials. CO2 lasers are the most common type of laser cutting equipment, capable of cutting and engraving various non-metallic materials (such as wood, acrylic, leather, paper, etc.)
Working principle
The working principle of CO2 laser cutting can be divided into several steps:
1. Laser generation:
The CO2 laser excites a mixed gas (mainly carbon dioxide, nitrogen and helium) through an electric current to form a laser.
The wavelength of the laser is about 10.6μm, which is well absorbed by many materials (especially non-metals).
2. Beam transmission:
The generated laser beam is guided through a series of reflectors and focused on the surface of the material through a focusing mirror.
The focused laser beam has an extremely high energy density and can produce very high temperatures on the surface of the material.
3. Material cutting:
When the laser beam is irradiated on the surface of the material, it is instantly heated to the melting or vaporization point to form a cut.
4. Automatic control and feedback:
Modern CO2 laser cutting machines are usually equipped with control systems that can automatically adjust cutting speed, laser power and beam focal length to ensure cutting quality and efficiency.
Through sensors and feedback systems, the cutting process can be monitored in real time to ensure the accuracy and safety of the workpiece.
CO2 laser cutting is widely used in many industries due to its high efficiency, high precision and adaptability. Its unique working principle and structural design enable it to handle complex cutting tasks, and its continuously evolving technology and continuously optimized equipment enable it to continue to occupy an important position in modern manufacturing.
CO2 laser cutting machines have been widely used in many industries, and their advantages and disadvantages have their own characteristics. The following is a detailed analysis of the advantages and disadvantages of CO2 laser cutting machines:
Advantages of CO2 Laser Cutting Machine
1. High precision:
CO2 laser cutting machines are able to achieve very high cutting accuracy, suitable for complex patterns and small parts that require fine processing.
2. Excellent cutting quality:
Due to the focusing ability of the laser beam, CO2 laser cutting achieves smooth and neat cutting edges, reducing the need for post-processing.
3. Fast cutting speed:
When it comes to cutting thin materials, CO2 laser cutting machines generally have faster cutting speeds, which improves production efficiency.
4. Contactless cutting:
Laser cutting is a contactless process that does not exert mechanical pressure on the material, thus reducing material deformation and damage.
5. High degree of automation:
Equipped with a control system that supports automated operation, it can automatically complete complex cutting tasks and improve production efficiency.
6. Wide range of cutting thickness:
Although there are some limitations in cutting thick materials, CO2 laser cutting machines are still able to handle a wide range of materials in thickness, from thin sheets to medium thickness materials.
7. Easy to process complex shapes:
Laser cutting machines can easily handle complex geometries and fine cutting paths, making them ideal for making complex patterns or crafts.
8. Small heat-affected zone:
The heat-affected zone generated by laser cutting is small, which can reduce thermal deformation and thermal damage of materials and maintain material properties.
9. Environmental protection:
The laser cutting process generates relatively little waste, and does not require the use of large amounts of cutting fluid and lubricants, which is relatively environmentally friendly.
10. Low maintenance requirements:
Although the initial investment is high, the maintenance frequency and cost of CO2 laser cutting machines are relatively low if used and maintained correctly.
Disadvantages of CO2 Laser Cutting Machine
1. Higher initial investment cost:
The initial investment in CO2 laser cutting machine is high, including the cost of equipment purchase, maintenance and laser. In addition, laser consumables and power consumption may also add to the operating costs.
2. Absorbability of CO2 laser:
CO2 laser has a long wavelength and has a low absorption rate for metal materials. In this case, metal cutting requires other laser types (e.g. fiber laser).
3. Limited ability to cut thick materials:
Although CO2 laser cutter is suitable for cutting thin materials, it has relatively weak cutting ability for thick metal materials.
4. Cutting speed is affected by material and thickness:
Although the cutting speed is faster, the efficiency of cutting for different materials and thicknesses varies greatly, and certain materials may be cut slower, resulting in lower productivity.
5. Laser tube life:
CO2 laser tubes have a limited service life, generally between a few thousand and tens of thousands of hours, however, as the use of time grows, the laser output power will decline and the laser tube may need to be replaced, which will increase the long-term operating costs of the enterprise.
CO2 laser cutting machines have performed well in many industries due to their high precision, fast speed and wide material applicability. However, problems such as high initial investment and limited ability to cut thick materials have also limited their application to a certain extent. Therefore, when choosing a laser cutting machine, you should fully consider your actual needs and budget to make the best choice.

The main differences between CO2 laser cutting machine and fiber laser cutting machine are light source, processing material, production cost, maintenance cost, cutting efficiency and other aspects.
● Different light source:
Fiber laser cutting machine generates laser beam through multiple diode pumps, while CO2 laser cutting machine uses CO2 laser tube to generate laser beam.
The laser beam of fiber laser cutting machine is transmitted to laser cutting head through soft fiber optic cable, while the laser beam of CO2 laser cutting machine is reflected to laser cutting head through reflection and focusing lens12.
● Different processing materials:
The beam wavelength of CO2 laser is 10.64μm, which is suitable for cutting non-metallic materials.
The beam wavelength of fiber laser is 1.064μm, which is 10 times shorter and suitable for cutting metal materials.
● Different production cost:
CO2 laser cutting machine consumes a lot of gas when working, and the photoelectric conversion rate is only 8%~10%.
Fiber laser cutting machine consumes less during processing, and the photoelectric conversion rate can reach 25%-30%, which is more energy-saving.
● Different maintenance costs:
CO2 laser tubes have complex structures, optical lenses are fragile, expensive, and have high maintenance costs.
Fiber laser cutting machines are basically maintenance-free, and wearing parts are durable and replaced less frequently12.
● Different cutting efficiency:
CO2 laser cutting machines have large beam diffusion during processing, which is not suitable for large-scale processing, and the processing speed of thick plates is slow.
Fiber laser cutting machines are characterized by high laser beam density, high intensity, high brightness, high conversion rate, and fast processing speed.
Fiber laser cutting machines and CO2 laser cutting machines each have their own advantages and applicable scenarios. Fiber laser cutting machines are more suitable for metal material processing due to their high efficiency, low maintenance cost and fast cutting speed, while CO2 laser cutting machines are more suitable for non-metal material processing.
