What is CNC Laser CO2?
CNC Laser CO2 is a type of laser cutting technology that uses a gas mixture of carbon dioxide, nitrogen, and helium to create a high-intensity laser beam. This beam is then directed onto the material to be cut or engraved, melting or vaporizing it with extreme precision. The process is controlled by a computer system that reads and executes instructions from a CAD (computer-aided design) program.
How Does CNC Laser CO2 Work?
CNC Laser CO2 machines work by generating a high-energy laser beam through the process of stimulated emission. This beam is then focused by a series of mirrors and lenses onto the surface of the material to be cut. The beam's intensity causes the material to melt, vaporize, or burn, depending on the laser's power and the material's composition. The CNC system ensures that the laser beam moves precisely according to the design file, cutting or engraving the material with great accuracy and speed.
Types of CNC Laser CO2 Machines
There are three main types of CNC Laser CO2 machines: Flying Optic Laser, Moving Material Laser, and Hybrid Laser.
Flying Optic Laser
Flying Optic Laser machines have a fixed cutting table, and the laser head moves over the material to be cut. This type of machine is best suited for thin materials and high-speed cutting.
Moving Material Laser
Moving Material Laser machines have a cutting table that moves in both the X and Y axes, while the laser head remains stationary. This type of machine is suitable for cutting thick materials and offers high accuracy.
Hybrid Laser
Hybrid Laser machines combine CO2 laser cutting with other cutting technologies, such as plasma or waterjet cutting. This type of machine is ideal for cutting thick and hard materials, such as metals.
Applications of CNC Laser CO2
CNC Laser CO2 machines have a wide range of applications in various industries, including:
