The 3 rollers HH-3R rolling 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 the execution of particularly delicate profiles. The machine is suitable for rolling pipes, lapping work, threading with a high class precision and for mass production of Scaffolding pipe jack and solid jacks screws etc.
