A CO2 glass laser cutting machine uses a 10.6 micrometer infrared laser beam to scribe and separate thin glass substrates. The laser heats a narrow line on the glass surface, and a controlled cooling jet creates a thermal stress crack that propagates cleanly through the material. This process is called stealth dicing or thermal scribe-and-break, and it produces edges that are smoother than mechanical diamond wheel cutting, with no micro-cracks or chipping.
Unlike fiber lasers that reflect off glass, CO2 wavelengths are absorbed by the glass surface, making them the standard for thin glass processing in display manufacturing. The machine handles glass from 0.1mm to 2mm thick, including soda-lime glass, borosilicate glass, and alkali-free display glass used in LCD and OLED panels.

Mechanical diamond wheel cutting causes micro-cracks and edge chipping that require post-processing polishing. Laser cutting produces clean edges that need no further finishing, and it can cut complex shapes (circles, holes, contours) that mechanical scoring cannot do efficiently.
FAQ:A: The CO2 process is optimized for thin glass up to 2mm. Thicker glass (over 3mm) is better processed with a UV laser or mechanical CNC glass cutting table.
A: The thermal scribe process produces minimal debris. A small amount of glass dust is extracted by the built-in fume system. The separated edge is smooth and does not require polishing.
A: Yes. The laser cuts through the glass substrate. Coated glass may require a lower power setting to avoid damaging the coating, and samples should be tested first.
A: The edge is smooth and perpendicular, with edge strength comparable to polished glass. For demanding applications, a light edge polishing step may still be recommended.
A: RF-excited CO2 lasers have a service life of 20,000-30,000 hours and can be re-gassed rather than replaced, reducing long-term operating cost.
