Roundo Section Bending Machines
Largest selection on the market ROUNDO is the worlds leading manufacturer of plate and section bending machines. The company was formed in 1964, and has since delivered almost 16000 machines to satisfied customers around the giobe. ROUNDO machines are world renowned for outstanding performance, reliability and quality. ROUNDO offers the largest selection of section bending machines on the market. We produce over 20 different standard sizes, from the, our smallest machine, to the, the strongest section bending machine in the world Our machines are always more powerful and more heavily proportioned in terms of frame, shaft size, bearings and drive torque than machines from other suppliers. CNC controls and a wide array of options are available for all models.
TWO BROAD RANGES
are basic machines for all types of section bending. The guide rolls are manually adjusted and fixed to the swing arms. The range of models, offers enhanced versatility due to the unique design of the hydraulic guide rolls.
MAIN ADVANTAGES WITH ROUNDO BENDING MACHINES
Heaviest proportioned main frame
The main frame on all ROUNDO section bending machines is welded steel construction, machined and line bored using the heaviest components of any comparable machine for added strength and rigidity. ROUNDO is the only manufacturer who stress relieves every frame after welding. Largest shaft diameters and bearing sizes.
Roll shafts are made from high strength chrome nickel alloy steel, and are the largest diameter shafts of any comparable machine. These heavily proportioned shafts help minimize deflection, resulting in improved bending. The roll shafts are journalled in oversized SKF roller bearings for greatest efficiency and long life. The standard tooling is a combination set for bending angles both leg out and leg in, flat bar on flat and on edge, T bar stem out and stem in as well as stem down, small square bar and even small solid round bar. Normally, no additional spacers are required. Highest drive torque and rotation speed ROUNDO section bending machines provide the greatest drive torque of any comparabe machine. Greater drive torque means the section can generally be rolled in fewer passes, often resulting in less deformation to the section being rolled. All three rolls are driven at all times. The maximum rotation speed on all models is generally 7 m min, considerably higher than other comparable machines.
Greatest bending rot force
The two lower rolls are individually adjusted by hydraulic cylinders. The rolls are sized to allow ROUNDO section bending machines to generate more bending power than any comparable machine, providing the largest section modulus capacity. Most powerful guide rolls ROUNDO section bending machines feature the largest, most powerful guide rolls available on the market. This allows them to take the twist out of the most massive sections within the capacity of the machine. The hardened steel guide rolls, including leg in guide rolls, are standard on every model.

CONTROLS
The ROUNDO Control is a PC based CNC control running under Microsoft Windows, providing an operator friendly graphical interface. This highly advanced and powerful system can controI up to 24 axes, including the main bending rolls, the powered pushing rolls and support devices, and even the special devices used to bend beams and channels on X X axis. The ROUNDO Control software includes a library of bending wizards to rapidly produce good parts. Even short runs can be efficiently rolled using this system. The CNC Control is available for all models. The ROUNDO Logic Control System is a PLC based control system designed and developed normally for small section and plate bending machines. This system can control up to 7 axes and the possibility to use USB memory allows infinite number of bending programs.
The ROUNDO Position Control system is a basic positioning control with possibility to preset two values for each axis. The positioning control automatically stops the movement of the bending roll when the pre set value is reached. The system is designed to make repetitive bends. Electronic digital readouts are available for all models to improve the positioning accuracy of the bending rolls when adjusted by the operator.

The S models are suitable for all types of section bending and reach up to, the most powerful section bending machine in the world. The three bending shafts are journalled in heavy duty SKF ball bearings. The guide rolls are hydraulically adjustable in three directions on most of the models two directions are optional on. The hardened steel guide rolls are used to control the attitude of the material going into and coming out of the bending rolls. They are used when bending angle leg out and leg in and can be effective in many other bending applications.
