You’ve seen it happen: the diamond wheel hits the surface, and suddenly you&rsquo;ve got &ldquo;chipping&rdquo; or &ldquo;shelling&rdquo; all along the edges. It&rsquo;s frustrating, it wastes material, and it looks sloppy. The fix is actually pretty simple: infrared (IR) preheating lamps. You just warm up the glass right before the cutter <a href="https://henruite.com">makes</a> its move.</p> <h2 id="how-it-actually-works">How it actually works</h2> <p>Think of it as relaxing the glass. Infrared waves dive into the surface and get the molecules vibrating, which makes the material less brittle. When the glass hits that <a href="https://goldisgood.com">sweet</a> spot in temperature, the surface tension drops. Now, the cutting wheel can create a <a href="https://o-yate.com">clean</a>, <a href="https://o-yate.net">controlled</a> fracture instead of a chaotic one. If you skip this, the energy from the cut just bounces around unevenly. That&rsquo;s exactly where those jagged, ugly chips come from.</p>
