Glass Bead Peening and Glass Bead Blasting

Glass bead peening is an effective way of improving the fatigue properties and resistance to stress corrosion cracking. Glass beads are hard and lightweight thus producing a high magnitude surface layer of residual compressive stress while leaving a smooth surface finish. They are available in smaller sizes than traditional steel peening media making them useful on delicate parts with intricate geometry. Also, they are chemically inert, recyclable and environmentally friendly. Air nozzle style equipment is the most commonly used means for this process.

Glass bead blasting

A glass bead peening technique also referred to as glass bead blasting is effective for performing deburring, cleaning, surface preparation, texturizing and finishing. Metal surfaces often need to be cleaned, textured or polished for aesthetic and functional purposes. In order to keep the surfaces free from iron contamination of steel blasting media while achieving a smooth, satin finish, glass bead blasting becomes a desirable metal surface preparation technique. This technique is economical, reliable and it does not damage metal parts or their surfaces during the cleaning process. In many cases, traditional blasting media abrades the surface which does not happen with glass beads.

How glass bead peening works for deburring parts?

When used in a precision operation, this process helps in removing burrs and feathered edges from metal surfaces. The main reason why this process is required is that corners and edges of metal parts must be smooth and finished for assembly and precise operations. Abrasives other than glass beads can sometimes remove the base metal from the surface of metal parts during the deburring process. It however offers quality deburring of corners and edges without removing of base metal.
