Glass lampshade is an important component of Home Decorative Lighting, smooth and bright glass lampshade in Chandelier Light, Wall Sconce for home decoration to add a lot of highlights. Edging and drilling of glass lampshades are critical steps in the manufacturing process, as they directly affect the aesthetics, safety, and ease of installation of the finished product. Mechanical grinding of glass is to use abrasives to grind off the unevenness of the glass under the pressure of the grinding disc and the relative movement of the glass surface, so that the glass surface becomes hairy. Coarse-grained abrasives have fast grinding speed and rough surface, so multiple abrasives are commonly used. Usually after the first rough grinding, there is a concave layer on the surface of the glass, and there is a micro-crack layer underneath, so the glass surface is astigmatism and opaque, and both the concave layer and the crack layer must be thrown away to obtain a bright glass. The drilling is to reserve the position of mounting screws or wire threading holes on the glass lampshade for subsequent assembly and use. The glass cover drilling process typically involves the precise drilling of holes in the glass cover, a process that requires high precision and meticulous operation to ensure that the location, size, and shape of the holes meet the design requirements.
