The manufacturing of modern architectural glass, particularly Low-E and solar control varieties, demands unparalleled precision. These specialized coatings, while crucial for energy efficiency and light management, present unique challenges during the cutting and breaking process. Achieving clean, damage-free edges is paramount for ensuring the long-term performance and aesthetic integrity of the finished product.
In a recent demonstration, a leading innovator in glass processing technology showcased a significant leap forward with their fully automatic float glass cutting and breaking system. This advanced system, capable of performing complex X-Y-Z cuts, integrates sophisticated control mechanisms to tackle the specific requirements of Low-E and solar control glass.
A key highlight of this system lies in its intelligent approach to Low-E edge deletion. This critical step, necessary to remove the coating from the cut edge to facilitate proper sealing in insulating glass units, often relies on grinding. However, controlling the temperature of the grinding wheel during this process is essential. Excessive heat can lead to coating damage, glazing of the wheel, and ultimately, inconsistent and compromised edges.
This is where the system’s real-time monitoring and automated correction capabilities truly shine. An integrated optical sensor continuously tracks the grinding wheel temperature with exceptional accuracy. This constant feedback loop allows the system to react instantaneously to any fluctuations. 
The power of this technology is most evident in its automated corrective actions. Should the grinding wheel temperature reach a pre-defined limit, the system automatically activates cooling measures. This proactive approach ensures that the grinding wheel is consistently maintained within its optimal operating temperature range. By preventing overheating and the detrimental effects of glazing, the system guarantees efficient and reliable edge deletion.
The integration of “LiTEC Temperature Control” by LiSEC in this system underscores a commitment to redefining efficiency and reliability in glass processing. By meticulously managing a critical variable like grinding wheel temperature, this automated system minimizes the risk of defects, reduces material waste, and ultimately, contributes to a higher quality finished product.
This technological advancement represents a significant step forward for manufacturers working with Low-E and solar control glass. The combination of precise cutting capabilities, real-time monitoring, and automated temperature control ensures a consistently high standard of edge quality, paving the way for enhanced productivity and superior glass performance in modern building applications.
