Peening parameters are controlled and constantly monitored by a state-of-the-art USF Vacu-Blast "Vacutrol" process control system operating via a PC under Windows.
According to USF Impact Finishers, it provides a fast-response service for the precision shot peening of aeroengine and aircraft structural components and is one of only a few companies in the world with this speciality.
