Hydraulic Thread Rolling Machine Three Roll Type (Specification) The
3 rollers HU-3R rolling machine operates hydraulically. The
simultaneously and concentricity of three forces at 120o 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 particulary delicate profiles. The machines is suitable
for rolling pipes, lapping work, threading with a high class precision
and profor mass duction of Scaffolding pipe jack and solid jacks screws etc. The maximum values specified above can not be achieved simultaneously H3R - 50 H - 100H - 120 Work Range Roll Dies Motor 3 Phase AC Coolant Pum Out
