In the pursuit of light electronic products, as the key material of glass substrate is also toward the goal of thinness. Because of the hard and brittle physical characteristics of glass, how to cut the glass substrate without cutting and how to eliminate the glass edge defects after cutting has been a breakthrough of all circles.
Glass cutting is the first step in the process of glass processing, and it is also the most widely used process. Some glass before processing, to the original piece of glass polishing, cutting, edge grinding, drilling, washing and drying treatment, some glass processing technology, processing after washing and drying, and then according to the use requirements of grinding and polishing, cutting, milling, drilling, washing and processing has become the ultimate product.
Glass after mechanical cutting, forming micro cracks in the edge of the glass, the traditional glass cutting is to directly reach the cutter machining segment size, however, the biggest problem is that the wheel cutting tool loss, especially in the face of high hardness of glass cutting, tool wear is very serious; in addition, cutting the mechanical type will cause edge damage, and with the substrate thickness is thinner, all kinds of crack caused by cutting the rapid increase, seriously affecting the quality of cutting process.
The glass substrate breaks through the characteristics of the glass that can not be bent. Therefore, the glass substrate is filled with a strong competitive power by the excellent optical characteristics, the temperature and the geometrical size stability of the glass.
Ultra thin glass is hard and brittle properties in rare defects and thin thickness, in the process due to deformation and stress, defects or defects for the existing extension and expansion, resulting in rupture of substrate. Therefore, in the process of the conversion process, ultra-thin glass flexible substrate must have sufficient mechanical reliability and impact resistance, and is not easy to happen in process of shifting fragment transmission, in order to ensure manufacturing production yield, so how to improve the mechanical strength of ultra-thin glass, will be the key the most important technology in the future when the real application of ultra-thin glass.
The future application of thin glass will gradually into the wisdom of handheld products, the glass panel manufacturers and international related industries also actively seek solutions to enhance the strength of the glass substrate, reducing the probability of subsequent damage to the application of the glass substrate, helps to enhance process yield.
