TWO BROAD RANGES
R1 to R6 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, R2S to R21S, offers enhanced versatility due to the unique design of the hydraulic guide rolls.
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 stressrelieves every frame after welding.
Roll shafts are made from highstrength chromenickel 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 legout and legin, flat bar on flat and on edge, Tbar stemout and stemin as well as stemdown, 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 "legin" guide rolls, are standard on every model.
