HRB-4 series HRB-4 series
  • Accurate, ease of operate, fastest roll bendings
  • Flat zone of the sheet edges is minimised
  • Pre-bending, conical bending and ellipse bending can be done easily
  • Double pre-bends (both ends) in one pass
  • Hydraulic and electrical systems have been safeguarded from overloads and require minimum maintenance. Hydraulic and electrical components are modular and designed according to world standards.
  • The sheet is controlled by tightening of top and bottom rolls
  • Most suitable bending operation for CNC applications. More efficient for cycle times
  • User friendly operations without dependence to operator competence.

A few optional accessories

  • CNC control unit- color- graphic diplay
  • NC control unit
  • Polished rolls
  • Variable speed control
  • Oil cooling
  • Side supports(both sides)
  • Vertical support(mechanical - Ø 2 m x 1,5 t)
  • Vertical support(hydraulic - Ø 3 mx 4 t)
  • Vertical support (hydraulic - Ø 3 mx 6 t)
  • Material feed table
  • Changeable top roll for smaller diameters

Standards accessories

  • CE norm
  • Control unit with digital readout
  • Conical bending
  • Induction hardened rolls
  • Side rolls controlled with PLC
  • Parallelism of the bottom rols by torsion bar
  • Sress relieved steel construction machine frame
  • Dual speed control
  • All rolls mounted in bearings
  • Hydraulic opening and easy pull out system
  • Central rolls are driven with hydraulic motor and planetary gear box
  • Electrical and hydraulical protection against overloads
  • Hydraulic pressure adjustable bottom rolls
  • All axis positioning with adjustable speed at CNC machines
