FEATURES
Robust Machine Body
The machine body is strengthen and lowered to minimise twisting and deformation. All components of the machine frame including the cross members are stress relieved after welding.
Planetary Swing Roll System for 60/80/100
The bending rolls are 2 independent axes which swing up in an orbit motion. The orbit motion minimises spring back. This allows a DURMA machine to roll tighter curves.
Manual side supports for 60/80/100
These are used to guide the material on the in feed and out feed side. These are excellent features to help minimise deformation.
Planetary Swing Roll System for 125/240/300/360
The bending rolls are 2 independent axes which swing up in an orbit motion. The orbit motion minimises spring back. This allows a DURMA machine to roll tighter curves.
Full hydraulic 3 axis side supports (Z,U,C axis) for 125/240/300/30
Optional for 60/80/100
Each side support features three independent hydraulic axes. These are used to guide the material on the in feed and out feed side. These are excellent features to help minimise deformation.
Hardened Former Rolls
The standard set of former rolls are manufactured for highly durable C4140 grade steel. They are manufacture on large CNC lathes with high precision. The working surfaces are induction hardened to HRC 54 ± 2. The tooling gap is adjusted by the threaded collar on the end of the spindle.
Digital Readout for 60/80/100/125
As standard the DURMA model PBH 60 sectional rolling machine has a digital readout display for the two bending rolls (X & Y axes). The operator can quickly and easily view the position of these axes. Push button control provides safe and easy movement.
Digital Readout for 240/300/360
As standard the DURMA range of sectional rolling machines have a digital readout display for the two bending rolls (X & Y axes). The operator can quickly and easily view the position of these axes. Push button control provides safe and easy movement of all 9 axes.
High Torque Drive System for 240/300/360
DURMA sectional rolls produce extremely high torque therefore you can bend the section with fewer steps. The rolls are powered by three independent hydraulic motors thought a planetary reduction gearbox. The strong hydraulic brake system does not allow the section to slip back. Pressure safety valves protect the hydraulic system from overload.
9 Axes Control for 240/300/360 Optional for 80/100/125
DURMA rolling machines have 9 independent hydraulic axes:
X Axis – Up and down movement of the left bending roll
Y Axis – Up and down movement of the right bending roll
R Axis – Rotation of the spindle via hydraulic motor
CL Axis – Rotation movement of the left support
UL Axis – Up and down movement of the left support
ZL Axis – In and out movement of the left support
CR Axis – Rotation movement of the right support
UR Axis – Up and down movement of the right support
ZR Axis – In and out movement of the right support
Electrical and Electronic System for 240/330/360
Only the World leading electrical and electronic components are used in DURMA machines. The system has current overload protection components integrated into it.
Hydraulic System for 240/300/360
Only the World leading hydraulic valve components are used in DURMA machines. This ensures precision movements of all axes and high response speeds. The hydraulic system has pressure safety valves to protect the system from overload.

Set of three forming rolls are available for all I, H, U profiles.
Upgrade to hydraulic Z axis
Optional for 60/80/100/125
This option gives hydraulic movement on the Z axis (Support arm in and out)
Upgrade to full hydraulic 3 axis side supports ( Z,U,C axis)
Each side support features three independent hydraulic axes. These are used to guide the material on the in feed and out feed side. These are excellent features to help minimise deformation.
I, H, U Profiles Deformation Prevention System
Optional for 125/240/300/360
Bending I, H, U profiles the “hard way” will cause some deformation on the inner surfaces and
side channels. Especially on these profiles because of the asymmetric load resulting in twisting.
Durma patented deformation preventing system decreases deformation. This option covers hydraulic press drive (shown as 1 in above diagram)
I, H, U Profiles Deformation Prevention System continued…
The Durma patented deformation preventing system slides back to return the machine to standard for bending other profiles. This saves enormous amounts of time and significantly increases productivity of your machine.
