Cutting through ultra-thick glass is a grind. Seriously. If you just shove a cutting wheel into a thick slab without any prep, you’re basically asking for trouble. The blade takes a beating, the edges come out jagged, and you’re burning through tools way too fast. That’s why we use medium-wave infrared (MWIR) lamps. Instead of fighting the glass, we target the cutting path and soften it up first. Here is the trick: most IR heat just bounces off the surface or stays shallow. But medium-wave radiation actually sinks into the glass. We’ve tuned these lamps to hit the exact wavelengths the glass likes to absorb. It creates this little “sweet spot” of heat. The glass doesn’t melt, but it softens just enough that the wheel glides through without having to fight the material. But you can’t just blast it with heat. If you spread the heat too wide, you risk warping the whole plate or, worse, causing a thermal shock that cracks everything. We use linear arrays to keep the beam tight and focused right on the score line. It’s a balancing act—you have to tweak the wattage to match how fast your cutting head is moving. The best part? Your tools actually last. When the glass is pre-softened, the friction just vanishes. We’ve noticed a huge difference in blade life. You stop that annoying cycle of replacing wheels every single shift because the mechanical stress is finally gone. One thing to watch out for, though: these lamps get hot. Really hot. You can’t just bolt them to a frame and call it a day. If you don’t have proper venting or a solid cooling system, you’ll burn out the lamp ends. If the cooling isn’t up to the task, those quartz envelopes will pop. It’s a small detail, but it’s the difference between a machine that runs for years and one that breaks down in a week.
