In Guyson's automated air blast peening machines, multiple nozzles, pre-set at the correct impact angle and stand-off distance, are aimed at the target surfaces.

With component rotation and the peening nozzle(s) vertically and horizontally traversing or oscillating, greater surface coverage can be obtained with fewer nozzles and lower compressed air usage.

The movements and blast pressures are all under PLC control, programmed as part of the operator selectable process recipe for each component to be peened.

What is shot peening?

Controlled shot peening is regularly being specified by the aerospace, automotive and nuclear industries to enhance component service life. It is a cold working process in which the surface of the component being processed is bombarded with small spherical media. Each piece of shot striking the surface of the component acts as a minuscule peening hammer, deforming the component surface and causing a small indentation or dimple. The overlapping dimples develop a thin layer of metal in residual compressive stress at or near the surface. Since nearly all fatigue and stress corrosion failures start at the surface of a part, the compressive stresses induced by shot peening can considerably increase component service life.

For further information on shot peening please read our latest 'shot peening brochure' - available from 'downloads'. This covers such items as 'what are Almen strips used for,' 'usage of Magna-Valves' and 'when to choose robotically controlled shot peening'. Also included are examples of equipment we have previously built for a wide range of customers.
