Finest Bending Performance
General Specifications
Up to 8000 mm Bending Lenghts Up to 200 mm Bending Thickness Accurate Easy to Operate Fast and Reliable Flat zone of the part is minimized Pre-bending conical bending and ellipse bending can be done easily Double pre-bends (both ends) in one pass The sheet reference is maintained by tightening of top and bottom rolls Most desirable bending operation for CNC applications More efficient for cycle times Hydraulic and electrical systems have been safeguarded from overloading and require minimum maintenance Hydraulic and electrical components are modual and designed according to world standards
Machinersquos body is strengthened and lowered to minimise the twists and deformation Machine body frame and steel bar connections are stress relieved after the welding operation
Robust Body Structure
High Torque Drive System enables Durma roller bending machines to bend metal sheets with less steps HRB-4 machines has top and bottom rolls powered by planetary reducer hydraulic motor and gear system HRB-3 machines has top and side rolls powered by planetary reducer hydraulic motor and gear system Strong Hydraulic Brake system does not allow the sheet to slip back Pressure safety valves are protecting the hydromotor and other components from overloads and peak pressures
High Torque Drive System
Hydraulic Opening
Side rolls are guided by swing beds which allows them to act as 2 independent axes moving on curve shape orbits Side rolls are approaches to the top roll on curve movement which allows to get perfect prebendings as well as spring back minimisation (Rectilinear Rolls System designed for top roll dia more than 460 mm)
Planetary Swing Rolls System
HRB Series Standard Features
Hydraulic opening drop-end for easy remove completed the bending

Strong body and angular bottom and side rolls enables to easily conical bend materials While machile machines in the market bends conical 3 times of top roll diameter Durma HRB machines can bend 15 times easily
Conical Bending System
Synchronized Rolls System
Hardened Rolls And Crowning System
HRB Series Standard Features
Side rolls triggered by 4 different strong hydraulic cylinders Syncronisation between Thanks to high prrecision load holding valves Bottom roll tightens different thickness of sheets without deformation and taking to the consideration of its paralelism by hydraulic adjustable pressure torsion bar
Highly durable carbon steel (C45) rolls are machined by CNC Lathes with high precision without creating notch effect Working surfaces of the rolls are induction hardened to HRC 54plusmn2 Rolls are machined as crowning shape to compansate the deflactions on the rolls during the bending
Strengthen Bearing System
Rolls are guided with spherical roller bearings and bronze housings Guiding system requires less lubrication and keeps it precision in long term
The standard control unit ensures that machinersquos bottom and side rollers operate smoothly

HRB Series Optional Features
In addition to standard user friendly control unit all bending steps are recorded for operator in teaching mode All reco-reded movements can be repeated using automatic mode NC control system has capacity to save 70 programs up to 100 steps each
NC Control Unit (HRB-4)
CNC Control Unit (HRB-4)
CNC control unit features a graphical control system that enables the operator to realize the bending step by step or automatically calculate bending process It includes a bending library that features polysentric and ellipse bending shapes
Special Support System
Especially the during bendings of the large diameter and thin metarial ellipse paralel corners and polycentric shaped may effect the precisions and can cause deformation of the metarial when there is not enough support
Optional hydraulic side and vertical supports the sheetrsquos stretch and prevent deterioration of the bending form in big shaped bending
Moveable gauges with hydraulic double cylinders are produced from St52 steel construction Sheet is easy sliding movement on supports by support rollers which is housing by bearings
Each support can be controlling from control panel separately It is possible to vertical supportrsquos capacity is to provide oslash 2000 mm to oslash6000mm sheet and 4 ton to 6 ton capacities Vertical and side support system can be controlling automatically NC mod in CNC and NC machines
Vertical and Side Support System
from the standard sheet support systems the double knuckle side support system may interfere and provides a pricise and perfect bendings if neeed the sizes of these support can be build according to the customers request

Finest Bending Performance
General Specifications
Up to 8000 mm Bending Lenghts Up to 200 mm Bending Thickness Accurate Easy to Operate Fast and Reliable Flat zone of the part is minimized Pre-bending conical bending and ellipse bending can be done easily Double pre-bends (both ends) in one pass The sheet reference is maintained by tightening of top and bottom rolls Most desirable bending operation for CNC applications More efficient for cycle times Hydraulic and electrical systems have been safeguarded from overloading and require minimum maintenance Hydraulic and electrical components are modual and designed according to world standards
Machinersquos body is strengthened and lowered to minimise the twists and deformation Machine body frame and steel bar connections are stress relieved after the welding operation
Robust Body Structure
High Torque Drive System enables Durma roller bending machines to bend metal sheets with less steps HRB-4 machines has top and bottom rolls powered by planetary reducer hydraulic motor and gear system HRB-3 machines has top and side rolls powered by planetary reducer hydraulic motor and gear system Strong Hydraulic Brake system does not allow the sheet to slip back Pressure safety valves are protecting the hydromotor and other components from overloads and peak pressures
High Torque Drive System
Hydraulic Opening
Side rolls are guided by swing beds which allows them to act as 2 independent axes moving on curve shape orbits Side rolls are approaches to the top roll on curve movement which allows to get perfect prebendings as well as spring back minimisation (Rectilinear Rolls System designed for top roll dia more than 460 mm)
Planetary Swing Rolls System
HRB Series Standard Features
Hydraulic opening drop-end for easy remove completed the bending

Strong body and angular bottom and side rolls enables to easily conical bend materials While machile machines in the market bends conical 3 times of top roll diameter Durma HRB machines can bend 15 times easily
Conical Bending System
Synchronized Rolls System
Hardened Rolls And Crowning System
HRB Series Standard Features
Side rolls triggered by 4 different strong hydraulic cylinders Syncronisation between Thanks to high prrecision load holding valves Bottom roll tightens different thickness of sheets without deformation and taking to the consideration of its paralelism by hydraulic adjustable pressure torsion bar
Highly durable carbon steel (C45) rolls are machined by CNC Lathes with high precision without creating notch effect Working surfaces of the rolls are induction hardened to HRC 54plusmn2 Rolls are machined as crowning shape to compansate the deflactions on the rolls during the bending
Strengthen Bearing System
Rolls are guided with spherical roller bearings and bronze housings Guiding system requires less lubrication and keeps it precision in long term
The standard control unit ensures that machinersquos bottom and side rollers operate smoothly
User Friendly Control Unit

HRB Series Optional Features
In addition to standard user friendly control unit all bending steps are recorded for operator in teaching mode All reco-reded movements can be repeated using automatic mode NC control system has capacity to save 70 programs up to 100 steps each
NC Control Unit (HRB-4)
CNC Control Unit (HRB-4)
CNC control unit features a graphical control system that enables the operator to realize the bending step by step or automatically calculate bending process It includes a bending library that features polysentric and ellipse bending shapes
Special Support System
Especially the during bendings of the large diameter and thin metarial ellipse paralel corners and polycentric shaped may effect the precisions and can cause deformation of the metarial when there is not enough support
Optional hydraulic side and vertical supports the sheetrsquos stretch and prevent deterioration of the bending form in big shaped bending
Moveable gauges with hydraulic double cylinders are produced from St52 steel construction Sheet is easy sliding movement on supports by support rollers which is housing by bearings
Each support can be controlling from control panel separately It is possible to vertical supportrsquos capacity is to provide oslash 2000 mm to oslash6000mm sheet and 4 ton to 6 ton capacities Vertical and side support system can be controlling automatically NC mod in CNC and NC machines
Vertical and Side Support System
from the standard sheet support systems the double knuckle side support system may interfere and provides a pricise and perfect bendings if neeed the sizes of these support can be build according to the customers request

Finest Bending Performance
General Specifications
Up to 8000 mm Bending Lenghts Up to 200 mm Bending Thickness Accurate Easy to Operate Fast and Reliable Flat zone of the part is minimized Pre-bending conical bending and ellipse bending can be done easily Double pre-bends (both ends) in one pass The sheet reference is maintained by tightening of top and bottom rolls Most desirable bending operation for CNC applications More efficient for cycle times Hydraulic and electrical systems have been safeguarded from overloading and require minimum maintenance Hydraulic and electrical components are modual and designed according to world standards
Machinersquos body is strengthened and lowered to minimise the twists and deformation Machine body frame and steel bar connections are stress relieved after the welding operation
Robust Body Structure
High Torque Drive System enables Durma roller bending machines to bend metal sheets with less steps HRB-4 machines has top and bottom rolls powered by planetary reducer hydraulic motor and gear system HRB-3 machines has top and side rolls powered by planetary reducer hydraulic motor and gear system Strong Hydraulic Brake system does not allow the sheet to slip back Pressure safety valves are protecting the hydromotor and other components from overloads and peak pressures
High Torque Drive System
Hydraulic Opening
Side rolls are guided by swing beds which allows them to act as 2 independent axes moving on curve shape orbits Side rolls are approaches to the top roll on curve movement which allows to get perfect prebendings as well as spring back minimisation (Rectilinear Rolls System designed for top roll dia more than 460 mm)
Planetary Swing Rolls System
HRB Series Standard Features
Hydraulic opening drop-end for easy remove completed the bending

Strong body and angular bottom and side rolls enables to easily conical bend materials While machile machines in the market bends conical 3 times of top roll diameter Durma HRB machines can bend 15 times easily
Conical Bending System
Synchronized Rolls System
Hardened Rolls And Crowning System
HRB Series Standard Features
Side rolls triggered by 4 different strong hydraulic cylinders Syncronisation between Thanks to high prrecision load holding valves Bottom roll tightens different thickness of sheets without deformation and taking to the consideration of its paralelism by hydraulic adjustable pressure torsion bar
Highly durable carbon steel (C45) rolls are machined by CNC Lathes with high precision without creating notch effect Working surfaces of the rolls are induction hardened to HRC 54plusmn2 Rolls are machined as crowning shape to compansate the deflactions on the rolls during the bending
Strengthen Bearing System
Rolls are guided with spherical roller bearings and bronze housings Guiding system requires less lubrication and keeps it precision in long term
The standard control unit ensures that machinersquos bottom and side rollers operate smoothly

HRB Series Optional Features
In addition to standard user friendly control unit all bending steps are recorded for operator in teaching mode All reco-reded movements can be repeated using automatic mode NC control system has capacity to save 70 programs up to 100 steps each
NC Control Unit (HRB-4)
CNC Control Unit (HRB-4)
CNC control unit features a graphical control system that enables the operator to realize the bending step by step or automatically calculate bending process It includes a bending library that features polysentric and ellipse bending shapes
Special Support System
Especially the during bendings of the large diameter and thin metarial ellipse paralel corners and polycentric shaped may effect the precisions and can cause deformation of the metarial when there is not enough support
Optional hydraulic side and vertical supports the sheetrsquos stretch and prevent deterioration of the bending form in big shaped bending
Moveable gauges with hydraulic double cylinders are produced from St52 steel construction Sheet is easy sliding movement on supports by support rollers which is housing by bearings
Each support can be controlling from control panel separately It is possible to vertical supportrsquos capacity is to provide oslash 2000 mm to oslash6000mm sheet and 4 ton to 6 ton capacities Vertical and side support system can be controlling automatically NC mod in CNC and NC machines
Vertical and Side Support System
from the standard sheet support systems the double knuckle side support system may interfere and provides a pricise and perfect bendings if neeed the sizes of these support can be build according to the customers request

ldquoDurma always strives to be your preferred partnerrdquoRobust 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 de-pendant on operator competence
Finest Bending Performance
General Specifications
Up to 8000 mm Bending Lenghts Up to 200 mm Bending Thickness Accurate Easy to Operate Fast and Reliable Flat zone of the part is minimized Pre-bending conical bending and ellipse bending can be done easily Double pre-bends (both ends) in one pass The sheet reference is maintained by tightening of top and bottom rolls Most desirable bending operation for CNC applications More efficient for cycle times Hydraulic and electrical systems have been safeguarded from overloading and require minimum maintenance Hydraulic and electrical components are modual and designed according to world standards
Machinersquos body is strengthened and lowered to minimise the twists and deformation Machine body frame and steel bar connections are stress relieved after the welding operation
Robust Body Structure
High Torque Drive System enables Durma roller bending machines to bend metal sheets with less steps HRB-4 machines has top and bottom rolls powered by planetary reducer hydraulic motor and gear system HRB-3 machines has top and side rolls powered by planetary reducer hydraulic motor and gear system Strong Hydraulic Brake system does not allow the sheet to slip back Pressure safety valves are protecting the hydromotor and other components from overloads and peak pressures
High Torque Drive System
Hydraulic Opening
Side rolls are guided by swing beds which allows them to act as 2 independent axes moving on curve shape orbits Side rolls are approaches to the top roll on curve movement which allows to get perfect prebendings as well as spring back minimisation (Rectilinear Rolls System designed for top roll dia more than 460 mm)
Planetary Swing Rolls System
HRB Series Standard Features
Hydraulic opening drop-end for easy remove completed the bending

Strong body and angular bottom and side rolls enables to easily conical bend materials While machile machines in the market bends conical 3 times of top roll diameter Durma HRB machines can bend 15 times easily
Conical Bending System
Synchronized Rolls System
Hardened Rolls And Crowning System
HRB Series Standard Features
Side rolls triggered by 4 different strong hydraulic cylinders Syncronisation between Thanks to high prrecision load holding valves Bottom roll tightens different thickness of sheets without deformation and taking to the consideration of its paralelism by hydraulic adjustable pressure torsion bar
Highly durable carbon steel (C45) rolls are machined by CNC Lathes with high precision without creating notch effect Working surfaces of the rolls are induction hardened to HRC 54plusmn2 Rolls are machined as crowning shape to compansate the deflactions on the rolls during the bending
Strengthen Bearing System
Rolls are guided with spherical roller bearings and bronze housings Guiding system requires less lubrication and keeps it precision in long term
The standard control unit ensures that machinersquos bottom and side rollers operate smoothly

HRB Series Optional Features
In addition to standard user friendly control unit all bending steps are recorded for operator in teaching mode All reco-reded movements can be repeated using automatic mode NC control system has capacity to save 70 programs up to 100 steps each
NC Control Unit (HRB-4)
CNC Control Unit (HRB-4)
CNC control unit features a graphical control system that enables the operator to realize the bending step by step or automatically calculate bending process It includes a bending library that features polysentric and ellipse bending shapes
Special Support System
Especially the during bendings of the large diameter and thin metarial ellipse paralel corners and polycentric shaped may effect the precisions and can cause deformation of the metarial when there is not enough support
Optional hydraulic side and vertical supports the sheetrsquos stretch and prevent deterioration of the bending form in big shaped bending
Moveable gauges with hydraulic double cylinders are produced from St52 steel construction Sheet is easy sliding movement on supports by support rollers which is housing by bearings
Each support can be controlling from control panel separately It is possible to vertical supportrsquos capacity is to provide oslash 2000 mm to oslash6000mm sheet and 4 ton to 6 ton capacities Vertical and side support system can be controlling automatically NC mod in CNC and NC machines
Vertical and Side Support System
from the standard sheet support systems the double knuckle side support system may interfere and provides a pricise and perfect bendings if neeed the sizes of these support can be build according to the customers request
