[0002] CNC machining is typically used to shape glass, such as in the molding of glass cover plates and touch screens with OGS structures. Conventional glass hole drilling typically involves using a cylindrical grinding wheel to grind a small hole from the center, then gradually expand it outwards until the hole is formed. However, because the grinding wheel's surface area is relatively small and the cutting depth must be adjusted based on process capabilities, the larger the hole, the longer it takes to drill.
