The rear column eccentric presses are particularly suitable for forming and blanking workings of small particulars, which can be carried out in single or continuous cycle. The actual production range provides flywheel and lag presses, from 20 to 315 tons. Thanks to the sophisticated calculation systems, our machines have been studied in the minimum details, checking the correct dimension of the different mechanical components with the finite element method. This allowed to obtain presses characterized by a high rigidity structure and a total reliability.
