1. Introduction to CO2 Laser Cutting

CO2 laser cutting is a precise and versatile cutting method that utilizes a high-powered CO2 laser beam to cut through various materials. These machines are commonly used in industries such as manufacturing, automotive, aerospace, and electronics. The CO2 laser beam is generated by exciting a mixture of carbon dioxide, nitrogen, and helium gases using an electrical discharge. This energized beam is then focused through a lens, creating a highly concentrated beam of light.

2. How CO2 Laser Cutting Machines Work

CO2 laser cutting machines work based on the principle of thermal material removal. The high-energy laser beam heats the material it comes into contact with, causing it to melt, vaporize, or burn away. The laser beam is controlled by computer numerical control (CNC), which precisely guides the beam along the desired cutting path. The focused laser beam delivers an intense amount of energy, ensuring clean and accurate cuts.

3. Advantages of CO2 Laser Cutting

CO2 laser cutting machines offer several advantages that make them popular in various industries:

i. Precision:
