Averoldi srl has created a department for the production of printing columns and special shafts up to 650 of diameter and 10 meters long. A rolling machine has been introduced which allows to perform metric threads and trapezoidal threads from diam. 80 up to diam. 330.
The realization of the thread by cold deformation, the absence of the drain for the threading with cutting tool, considerably increases their resistance and therefore the service life.
