HRB-3 SERIES

HRB-3 SERIES

hrb3-kck-zmn
  • ƒƒ 6′ – 14′ Bending Lengths
  • ƒƒ 1/4″ – 2″ Bending Thicknesses
  • ƒƒ Flexible machine for medium to thick material
  • ƒƒ Cost effective solutions for large diameters
  • ƒƒ Wide working range
  • ƒƒ Excellent for rolling cones
  • ƒƒ Great value for precision and reliability
  • ƒƒ All rolls are driven with superior torque and speed

Standard Equipment

• Touch screen control unit with four multi-pass programmable digital readouts
• Dual speed control (fast/slow)
• Cone bending
• Induction hardened rolls (HRC 58)
• Highly durable forged 4140 alloy steel rolls machined by CNC Lathes with optimal crown (special crown upon request)
• Machine body constructed of stress-relieved high-yield steel
• Side rolls electronically positioned and synchronized with PLC and high-end precision digital scales
• Automatic rolls peripheral speed compensation (optimum distribution of torque)
• Rolls seated in spherical bearings
• Top roll hydraulic opening device (drop end) with easy pull out system
• All three rolls driven:
• Top roll driven with hydraulic motor and planetary gear box
• Side rolls up to 14.17" are hydraulic motor driven
• Side rolls 14.17" and above are driven with a combination of hydraulic motors and planetary gear boxes
• Rolls with an 17.72" or larger top roll come standard with rectilinear guides.
• Safety barrier
• Electrical and hydraulic protection against overloads
• World standard electrical and hydraulic components (parts stocked by JMT or available off-the-shelf from your local supplier)
• Permanent lubrication

Optional Equipment

• Polished Rolls
• Variable speed control
• Wired or wireless remote
• Oil Cooler
• Side support system (both sides)
• Preparation for vertical support system
• Vertical overhead support system (mechanical or hydraulic)
• Material feeding table
• Changeable top roll for smaller diameters
• Extended rolls for section/profile bending
• Welding possibility on the machine
