Abstract

Bushhammering system in which such working operation is effected by means of a plurality of sharpened elements (221), which are pushed in succession against the surface to be treated with a suitable pressure, so that each of them penetrates fairly in the material and by shifting itself chips such material, by removing correspondent particles therefrom. The device performing such system is composed of a discoidal plate (10), fixable on a correspondent rotating support (30) and provided at its lower part with some rotating units (20), each comprising as associated roll (22) radially pivoted to said discoidal plate (10) on an associated support (21), which is slidable in a corresponding radial guide groove (11) provided on said discoidal plate (10) and fixable removably thereto by means of a unit stud bolt (23)-nut (231), said roll (22) being also provided on its surface of rotation with a plurality of sharpened elements (221) having a considerable superficial hardness and a high mechanical strenght. The resulting group of rolls (22) engages with a fair pressure the surface of the part to be worked and, by imparting an adequate relative movement between said part to be worked and said device which is contemporaneously put in rotation, one can obtain the bushhammering operation for the entire desired surface thereof.
