Hydraulic Thread Rolling Machine 3 Roll Type
The 3 rollers HH-3R rolling machine operates hydraulically. The simultaneously and concentricity of three forces at 120° assures stability of the work piece during the rolling and as consequences 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 high class precision and for mass production of Scaffolding pipe jack and solid jacks screws etc.
