Rolling machines DURMA HRB-3, HRB-3V, HRB-4, MRB, etc.

• Movable shaft specially for medium thickness;
• Cost-effective solutions for large diameters;
• Wide operating range;
• High quality of cone bends;
• High levels of accuracy and reliability;
• All 3 rolls are driven by the torque and speed of the upper roll.

• Especially for thin sheets of small sizes;
• Easy pre-bending thanks to the upper and lower rolls holding the workpiece;
• Cost-effective solutions for small and medium-sized enterprises;
• Wide range of industrial applications.

3-roller sheet bending machines with variable axis HRB-3V series
The machines are designed for bending medium and thick sheets. Unlike conventional cylindrical machines, the lower rolls move horizontally to the right and left, and the upper rolls move up and down. As in 4-roll machines, steel loading runs parallel to the floor, so the machine recess can be located at the working level.

• Precise, easily controlled, fast rolling of the sheet by rolls;
• Minimum length of the straight section of the sheet edge;
• Ease of performing pre-bending and bending into a cone and an ellipse;
• Double pre-bending (on both sides) in one pass;
• Hydraulic and electrical systems are protected from overloads and require minimal maintenance;
• The position of the sheet is controlled by pressing the upper and lower rolls;
• Optimal organization of the bending process for the implementation of tasks with the use of CNC;
• Optimal residence time of the workpiece at the production site;
• User-oriented management that does not require special operator training.

• HRB-3. Technical specifications.
• HRB-3V. Technical specifications.
• HRB-4. Technical specifications.
• MRB. Technical specifications.
