The lifespan of a CO2 laser cutting machine primarily depends on its internal consumables. There are three main parts to consider: the laser tube, the focusing lens, and the reflector. As you use the machine longer, these three consumables, especially the laser tube, are likely to experience problems, requiring replacement.
That said, if you frequently use the laser engraving machine (not heavy-duty), a high-quality laser tube can last over 2000 hours without issues. However, if you use the machine for heavy-duty tasks requiring maximum power, the tube may only last about 500 hours.
Of course, choosing a reputable company will ensure you have comprehensive technical support and after-sales service, and they will provide warranty coverage for product quality issues.
