ROUNDO ANGLE ROLL


 

 

ROUNDO ANGLE & STRUCTURAL BENDING ROLLS 

ROUNDO offers the largest selection of angle bending machines on the market with over 25 different standard sizes, from the R-1, the smallest machine, to the R-21-S, the strongest section bending machine in the world! The 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.

ROUNDO rolls over the competition by giving you:

Heaviest Proportioned Frame - for added strength and rigidity

Largest Diameter Roll Shafts - to minimize deflection, improving bending results

Largest Roll Shaft Bearings - for greatest efficiency and long life

Highest Drive Torque - means fewer passes and less deformation

Greatest Bending Roll Force - generated by the rolls, providing the largest section modulus capacity

Most Powerful Guide Rolls - to efficiently take the twist out of the heaviest sections

TWO BROAD RANGES
R-1 to R-6 are basic machines for all types of section bending. The guide rolls are manually adjusted and fixed to the swing arms. The range of "S"-models, R-2-S to R-21-S, offers enhanced versatility due to the unique design of the hydraulic guide rolls.ROUNDO R3S

MAIN ADVANTAGES WITH ROUNDO BENDING MACHINES
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.

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.

ROUNDO angle bending machines provide the greatest drive torque of any comparable 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 23 feet/min, considerably faster than other comparable machines.

The two lower rolls are individually adjusted by hydraulic cylinders. The rolls are sized to allow ROUNDO angle bending machines to generate more bending power than any comparable machine, providing the largest section modulus capacity.

MOST POWERFUL GUIDE ROLLS
ROUNDO angle 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.
