Automated Shot Peening Equipment Guyson automated shot peening systems are designed to eliminate variations in manual blast processes. Depending on the geometry of the components, the cycle time available and the flow of work, a variety of different automated shot peening systems are available from Guyson, these include tumble peen, conveyor peen, rotary table peen, spindle peen and robotically controlled. Contact Guyson for further advice on the most suitable for your products. 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. 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.
