Ultrasonic Peening (UP)

A machine for shot peening of engine components using the "Ultrasonic peening" with balls (stressonic®) process. The applied robots position a "shot peening tool" with repeatable accuracy to the component which is centrally clamped onto a turning fixture and can be machined on both sides. Machining is made with rotating or stationary component, i.e. the component is rotating under the tool or the rotation is switched off for machining of apertures. Components and tools are changed by the operator, with the robots going to the tool change position for an easier changing. The components are rotation-symmetrical blisks (Blade Integrated Disk, engine disks) and consist of nickel-based alloys, high-alloy steels and titanium.
