The excellent properties of the glass beads make it suitable for use in cleaning or deburring workpieces with strict deviations without damaging the surface of the workpiece. Moreover, the inherent strength of the glass beads makes it suitable for use in equipment capable of circulating abrasives.
Glass beads are widely used to treat the surface of workpieces with residual tension or under cyclic pressure to produce compressive stress layers for surface strengthening purposes. The use of glass beads to strengthen the surface of the workpiece reduces potential hazards such as surface erosion or surface fatigue.
The use of glass beads for surface treatment is very economical and accurate.
The chemical properties of glass beads are inert and non-toxic, and no iron or other harmful substances remain on the surface of the workpiece during use, and will not adversely affect the surrounding environment.
