Shot-peening falls in the category of “special processes” that are not verifiable ex post. Therefore, the only way to control the process is to be sure that the operational settings constantly remain within strict tolerances throughout the treatment. The compressed-air systems are universally held to provide the best possible quality. In this case, an anthropomorphic robot managing the shot-peening lance and two additional axes interpolated for the movement of the tables/blades carrying satellites make it possible to perform the shot peening in the best possible conditions. Appropriate instruments are able to manage the size of the grit and the flow rates, while a PLC enables proper management of all operating parameters, keeping them within the expected ranges during the entire duration of the processing.
