Abstract
A controlled shot-peening of blisk blades () uses a stream of spherical shot-peening medium transported by compressed air or water. The shot is driven essentially at a right angle onto each blisk blade individually, actually simultaneously on both blade sides, and with identical impact intensity and immediately opposite on both sides in several side-by-side processing paths extending over the entire blade surface. A dual-nozzle unit () is linearly moveable in two directions normal to each other, and swivellable about an X and a Y axis. The unit () includes two preferably rectangular, essentially parallel arranged, shot-peening nozzles (), whose spacing is settable in accordance with the blade profile, each of which has a nozzle opening situated at the same level and facing the pressure or the suction side of the respective blisk blade, and featuring identical distance to the respective blade surface during shot-peening.
