Glass is an important industrial material. Due to its brittle material, it is easily broken by external forces during processing. For example, mechanical stress and thermal influence can cause glass to break, so the precision of the glass material processing process is very high. Unlike traditional mechanical cutting methods, the energy of the laser beam cuts glass in a non-contact manner. This energy heats the specified part of the workpiece to a predefined temperature. This rapid heating process is followed by rapid cooling, so that a vertical stress zone is generated inside the glass, and a crack without chips or cracks appears in this direction. Because the cracks are only caused by heat and not mechanical reasons, there will be no serious chips and micro-cracks.
Therefore, the intensity of laser cutting edges is stronger than traditional scribing and dividing methods. Precision and efficiency have also been greatly improved. In addition, the occurrence of broken glass can be completely avoided.
