• Four-roll design and construction. Compact design for minimal floor space
• Welded, all-steel, heavily proportioned, thermally stressed-relieved frame and drop end
• Rolls shafts journaled in radial bearings
• Induction-hardened SAE 1050 steel bars, hardened to 58-60 Rockwell C are used for the rolls. Rolls are precisely machined with crowning to compensate for deflection under load.
• Fully hydraulic.
• Two-roll drive. The upper and lower central rolls are driven from a central hydraulic system, equipped with overload protection, by a hydraulic motor through a planetary gearbox. The lower roll is coupled to the top roll by a cardan joint system with gears - to provide rotation that ensures the material is appropriately secure throughout the bending process.
• The lower central roll and the two side bending rolls are hydraulically and individually adjustable and tiltable.
• Each side roll is adjustable hydraulically and independently to provide double pre-bending; therefore, each end of the workpiece can be prebent and then rolled with only one insertion of the workpiece into the machine.
• Linear movement of the side rolls with hydraulic pistons
• Dual rolling speeds
• Hydraulic balancing system for rolls parallelism
• Robust drop end, hydraulically operated
• Controls for all functions and electronic digital readouts in a rolling console
• Cone bending attachment is standard equipment; and the side rolls can be tilted for more effective cone rolling, after which they can be easily paralleled for normal bending.
• 3-Electronic digital readouts (LED) for the positions of the side rolls and the lower roll, each with programmable roll position pre-set and memory
• Components are from world-renowned sources
• Pre-arranged for easy retro-fit of overhead and side support devices if required after machine has been put into operation
• Built according to stringent European standards for design, production and quality and bearing the CE-Mark of certification

STANDARD EQUIPMENT:

• Two-roll drive. The upper and lower central rolls are driven by a hydraulic motor through a planetary gearbox
• Induction hardened and crowned rolls
• Hydraulic adjustment of the lower central roll and of the side rolls, each independently
• Hydraulic drop end for easy removal of the completed cylinder
• Hydraulic system complete with controls
• Linear movement (slide) of the side rolls
• Dual rolling speeds
• Hydraulic balancing system for parallelism of the rolls
• Manual central lubrication
• Cone bending attachment
• Operating controls in a rolling console for all functions including adjustment of the lower and side rolls, for paralleling and tilting the side rolls (for cone rolling) and for operation of the drop end
• 3-Electronic digital readouts (LED) for the positions of the side rolls and the lower central roll are mounted in the rolling control console, each with programmable roll position pre-set and memory
• Electric motor controls. Electrics for 3/60/220/440. Low voltage at the controls
• Overload and under voltage protection. Emergency stop wires at the front and rear of the machine.
• Hydraulics by Rexroth, Bosch, Duplomatic or Parker
• Electrics by Siemens, NAIS or Telemecanique
• Bearings by FAG and SKF
• 2-Operating Manual/Parts List

With prebending, resulting flat ends are 1-1/2 to 2 times plate thickness or less.
Plate bending capacities are based on steel up to 38,000 PSI yield strength.
Cone bending capacity is 50% of each width and thickness capacities.
