Hardened Rolls And Crowning System
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 54 2 Rolls are machined as crowning shape to compensate the deflections on the rolls during the bending.

Conical Bending System
By strong body and angular bottom and side rolls, wide angle & small diameter conical parts are easily bend. While other machines in the market are bending conical bending's of 3 times of top roll, Durma HRB-4 machines can bend conical bending of 1.5 times easily.

Digital readout
Ensures the machine's bottom and side rollers' synchronous operation. This process is provided via the PLC with 6-axis control and touch screen operator panel. Bending up to 5 steps of the program, is ease of use and saves time.

NC Control
In addition to the Digital readout control system, In teaching mode for the operator to bend all the steps are recorded respectively. In automatic mode all recorded movements are repeated, respectively by the machine. NC control system has the capacity to save 70 programs consisting of Max 100-steps.

CNC Control
CNC control system, in addition to the NC control system with its graphical control system allows the bending done step by step or automatically calculating the bending steps without the need for operator skill. Due to ready bending shapes polisentrik bending and twisting like an ellipse, is also easily done

Rectilinear Rolls

Rolls and their positions are selected after long term engineering, tests and evaluation periods.

Side rolls are guided by linear beds which allow them to act as 2 independent axes moving on rectilinear plane. Better pre-bending and reduced spring back are achieved.
