Shot Peening Machine for Aerospace Industry

Controlled shot peening is regularly being specified by the aerospace to enhance component service life. It is a cold working process in which the surface of the component being processed is bombarded with small spherical media. Each piece of shot striking the surface of the component acts as a minuscule peening hammer, deforming the component surface and causing a small indentation or dimple. The overlapping dimples develop a thin layer of metal in residual compressive stress at or near the surface. . Since nearly all fatigue and stress corrosion failures start at the surface of a part, the compressive stresses induced by shot peening can considerably increase component service life.

6 Axis Robotic Shot Peening Machine :

SURFEX 6 Axis Robotic Shot peening machine is designed to open aerospace components to generate the controlled compressive stress to the surface and to enhance the surface properties, increase fatigue strength by creating small dimples which increase life of components. This system has capacity to peen jobs upto 650 mm length and 350 mm width and 100 mm height.

Process consistency in shot peening is vital and SURFEX systems are custom designed to control all the critical variables to suit each application. The shot size is controlled with screen classifiers and its shape is controlled with roundness classifiers to meet International rquirements. Shot flow rate [kg/min] is monitored and close loop controlled using Magna Valves for ferrous/non ferrous media. The shot replenisher automatically top-up the media.
