Abstract:
Traditional methods of shot peening, with air nozzles, have been eclipsed by centrifugal wheel peening machines in many applications. New equipment designs and methods have
been developed which offer high capacity, uniform coverage and programable control repeatability. Tests are described which show the centrifugal wheels achieve more precise
shot velocity control than air nozzles while being many times more energy efficient. Special, aimable, centrifugal wheel peening systems have been developed for the
aerospace industry to form wing skins to contour, improve the fatigue life of parts and prevent stress corrosion cracking.
