Abstract

Method to forge metallic pieces with a swaging machine, whereby during the rough-shaping step the hammers carry out a long stroke with a low number of hammer blows, whereas during the finishing step the hammers carry out a short stroke with a great number of hammer blows. Swaging machines suitable to perform the above method. <IMAGE>
