Glass bead is a kind of abrasive with unique characteristics, widely used in cleaning or metal surface strengthening process, mainly used in sandblasting equipment. Glass beads are made by crushing and sorting high-quality broken glass. During the manufacturing process, the broken glass shall be melted into a sphere and annealed to eliminate internal stress and prevent damage. This transparent and clear spherical structure product will not have particles embedded in the workpiece, contaminate the workpiece or cause other damage. Using different size of grinding tools and different operation parameters, the glass bead will get different glossiness on the surface of the workpiece. It can produce special decoration effect to select the shot peening glass bead for controlling sand blasting which is locally covered on the workpiece surface.


The excellent performance of glass bead makes it very suitable for the selection of workpieces with strict deviation requirements, and it will not damage the surface of workpieces when cleaning or deburring. In addition, the inherent strength of glass beads makes them suitable for equipment with recyclable abrasives
