Cutting through ultra-thick glass is a brutal process. There’s just so much friction and stress involved that if you try to score it cold, you’ll chew through your cutting wheels in a heartbeat. It’s a waste of time and money. That’s why we use high-penetration infrared (IR) lamps. We basically prep the glass by heating up the cutting path before the wheel even touches the surface. The trick is getting the heat deep inside. Most heating elements just warm the surface, which doesn’t do much for thick plates. We use shortwave IR because those wavelengths actually sink into the glass. We aren’t trying to melt the stuff. We just want to lower the viscosity and ease up on that internal tension. When the wheel finally hits that pre-heated line, it just glides. It feels smoother, the score is cleaner, and your wheels actually last. To make this work, you need lamps with some serious punch. We stick with quartz-halogen tubes because they heat up fast—which is a must when your cutting heads are on the move. But you have to be careful. It’s a balancing act. If you crank the heat too high, you’ll shock the glass and it’ll crack right in front of you. Too low? And you’re right back to destroying your wheels. A few things to watch out for during setup. If you’re adding this to an existing line, you can’t just “set it and forget it.” You need an IR sensor to keep an eye on the surface temp in real-time. And a heads-up: these lamps put off a ton of stray heat. If your cooling system isn’t up to the task, you’re going to fry your electronics. It’s a simple mistake, but a costly one.
