What Is a CO2 Laser Cutter?
CO2 laser cutting machine is a kind of equipment that utilizes CO2 laser as a cutting tool to achieve efficient and precise cutting. It has a wide range of applications in the packaging and printing industry, manufacturing industry, crafts and gifts industry, and has become an indispensable and important equipment in modern industrial production.
By focusing the CO2 laser into a high energy density beam, the CO2 laser cutting machine instantly heats up the surface of the material to the melting or vaporizing temperature, thus realizing the cutting of the material. The CO2 laser cutting machine can cut many different kinds of materials, such as plastics, paper, fabrics, etc., and is characterized by high speed, high precision and high efficiency.
In industrial production, CO2 laser cutting machine can be used for processing various parts and components, making signs and logos, cutting packaging materials and many other applications. Its use can not only improve production efficiency and reduce labor costs, but also realize the cutting and processing of complex shapes, which is an important processing equipment in modern industrial production.

How Do CO2 Laser Cutter Work?
The working principle of CO2 laser cutting machine is to use CO2 gas to generate laser light through excitation, and then focus the laser beam into a high energy density beam, through the instantaneous heating of the surface of the material to realize the cutting process. The following is the working process of CO2 laser cutting machine:
- Laser Generator Generates Laser: The laser generator in the CO2 laser cutting machine generates CO2 laser, by adding electricity to the CO2 gas and exciting the gas molecules, so as to make them emit photons and get a monochromatic and high-energy laser beam.
- Beam Delivery and Shaping: The laser beam is delivered, shaped and focused through lenses or mirrors into a high energy density beam that can be accurately directed at the work material.
- Table Movement: The table can be moved along the X and Y axes to control the position of the laser beam to achieve the desired cut shape.
- Cutting process: The laser beam irradiates the surface of the workpiece, and the laser energy locally heats, melts or vaporizes the work material to form a cut mark. At the same time, the table moves or the laser head moves to complete the whole cutting process.
- Air duct blowing: Auxiliary gases (e.g., oxygen, nitrogen) are usually used in the CO2 laser cutting process to help remove the melted material and keep the cutting opening clean.
- Control system: The cutting process can be controlled by computer numerical control (CNC) system, which precisely controls the laser power, speed and position to realize high-precision and high-efficiency cutting.
Through the above working steps, CO2 laser cutting machine can complete the cutting and processing of various materials, which is widely used in cutting, engraving, marking and other process work in the field of industrial production.
