How Does a CO2 Laser Marking Machine Work?
A CO2 laser marking machine operates by focusing a high-power laser beam onto the material to be marked. The laser energy is absorbed by the material, causing it to heat up rapidly and vaporize. This process creates a permanent mark or engraving on the material's surface.
The key steps involved in the CO2 laser marking process are:
1. Laser Generation: The CO2 laser generates a high-power beam of light at a specific wavelength, typically 10.6 microns.
2. Beam Delivery: The laser beam is directed through a series of optical components, including mirrors and lenses, to focus it onto the material.
3. Material Interaction: When the focused laser beam strikes the material, its energy is absorbed, causing the material to heat up and vaporize.
4. Mark Formation: The vaporization process creates a permanent mark or engraving on the material's surface.
5. Cooling: After the marking process, the material may need to be cooled to prevent damage or distortion.
