At the Christchurch Engine Centre, post-processing expert Rösler UK has worked with Pratt & Whitney to improve their component finishing process. The project replaced an antiquated robot shot blasting equipment with a sophisticated, closed-loop system maximizing process control.
Consistent surface textures guaranteed by this novel method are vital for coating adherence on aircraft components. Pratt & Whitney is a global leader in designing, and manufacturing auxiliary power units. It has now shifted its focus to front-edge innovation in aerospace engineering.
By using additive manufacturing (AM) technology, Pratt & Whitney has improved the performance and efficiency of its goods. Pratt & Whitney first used AM to manufacture intricate engine components, allowing for design freedom and material economy.
In aerospace production, shot blasting is essential as it removes contaminants and produces a consistent texture by preparing metal surfaces.
For components subjected to harsh circumstances, this is essential. Tony Pugh, Rösler UK’s Aerospace Projects Manager, underlined the requirement of improved process control to get consistent surface texture and coating adherence.
It results in the closed-loop system measuring and adjusting key process variables (KPVs), including blast media flow, air pressure, and nozzle distance. Recycling the blasting media reduces environmental effects and trash as well.
Rösler’s sophisticated technique helps Pratt & Whitney’s complex rotative components require exact surface treatment; the system manages difficult geometries without sacrificing the structural integrity of the components.
Adopting ABB robots and offline programming improves the shot-blasting process’s flexibility and accuracy. Safe and simple maintenance guaranteed by the ergonomic system design is vital in industrial environments.
Rösler’s work with Pratt & Whitney shows a notable improvement in aeronautical component finishing. This cooperation emphasizes the need for ongoing development and adaptation in the aerospace sector to sustain the desired quality.
