SHOT PEENING

We have a shot peening machine with a rubber tape, with 1 meter mouth. The machine is loaded with stainless steel balls with a diameter of 0.4 mm. A turbine projected at high speed the balls against the pieces in treatment. Depending on machine control parameters (speed of rotation of the turbine, rotation speed of the tape, the number of pieces and duration of the treatment) we execute:

–       Cleaning of the surfaces in order to achieve satin finish;
–       Shot peening.

The shot peening is performed mainly on mechanical components fatigue stressed in order to improve their performance. In particular, we execute the shot peening of wire and strip springs and we can certify the degree of intensity of the performed treatment by using the ALMEN scale.
