DURMA HRB-4 Series Roll Bending Machine
“Fast, Accurate and Easy to Operate”
Four plate rolls are more precise, productive, versatile, faster,
safer and easier to operate than three roll machines.
They are less dependent on operator competence.
Ideal for bending plates up to 200 mm thick.
Robust machine body and construction ensure long machine life and low maintenance. High torque drive system allows HRB to achieve shorter cycle times. User friendly control units makes it possible to be less dependant on operator competence.
HRB-4 Roll Bending today, tomorrow and forever with you.

* On mentioned models : Ø Dmin= Ødx2 (pre bending) ; Ødx4 (bending)
The mentioned values above is only works for 240 N/mm²
Different material and widths ; can be calculated by DURMA Roll Bending Calculator Conic bending capacities depends on the angle and half value of mentioned values above Weight and motor powers optionally goes higher levels with additionals.
