The STI HT3R machine operates hydraulically. The simultaneously and concentricity of three forces at 1200 assure stability of the work piece during the rolling and as a consequence the maximum geometrical precision of the work piece. The elimination of the support blade consents a better finishing of the piece and execution of particularly delicate profiles. The machine is suitable for rolling pipes, lapping work, threading with a high class precision and for mass production for items such as scaffolding pipe jack, solid jacks screws, tie rod etc.
