Abstract:  
The apparatus for the surface treating of work pieces comprises a motor and a centrifugal throwing wheel connected for rotation to the motor, the throwing wheel having an axially arranged feed inlet for receiving peening particles to be projected into impingement with the work piece to be treated. A frame is provided to pivotally support the motor and throwing wheel about a first axis which is substantially coincident with the axis of rotation of the throwing wheel. A base member is pivotally connected to the frame for supporting the latter for movement about a second axis substantially normal to the axis of the throwing wheel. A peening particle supply conduit is disposed to communicate with a supply of peening particles and the feed inlet for delivering peening particles to the throwing wheel. The supply conduit is constructed and arranged so that portions of its longitudinal axie lie coincident with said first and second axes. A remote controlled indexing means is connected to coact with the frame, throwing wheel and motor to rotate the motor and throwing wheel about the first and second axes to thereby effect adjustment of the throwing wheel in a multiplicity of positions relative to the work piece to be treated.
