HeavyBend tube bending machine



Precision and power

The HeavyBend line is the right bending solution when extreme rigidity, structural strength and guaranteed repeatability are necessary.

The bending head movements provides an easier loading of raw materials and unloading of the finished parts. The direct transmission of the bending axis ensures optimal results even in the presence of high torque requirements.

Heavy Bend tube benders are also equipped with a DC Bus energy saving system with active regeneration of the electrical current, which guarantees energy savings of up to 40% of the absorbed powers.

  • From 1 to 7 axes brushless electric axes, controlled by CNC.
  • System compliant with CE requirements thanks to safety systems with laser barriers and protections.
  • Separate and ergonomic control pulpit with 14”/ 21” multitouch video according to the configuration.
  • The plant can be equipped with hydraulic unit for cutting, punching and marking.
  • Safety area adjustable according to different bending lengths.
  • Remote assistance available.
  • Quick interchangeability of the bending system: compression, generation and calandaring.
  • Direct drive of the bending axis.


  • Wide range of profiles (round, square and special profiles).
  • Absolute position repeatability due to irreversible toggle locking of with absolute positioning.
  • Bending of complex shapes thanks to limited dimensions of the bending head.
  • Bending head with interchangeable passing shaft in order to use preexisting tools.
  • Excellent bending quality thanks to the wide range of accessories such as wiper die, shaped clamps, split bend die and mandrel lubrication system.
  • Driver with regenerative systems with energy savings of up to 40%.
  • Mechanical predisposition to change the bending direction and to increase the useful length of raw material.
  • Flexible system thanks to the possibility of multi-stack and multi-radius bending tools.
  • Quick setting time allows to change sectors without disassembling the collet’s body thanks to quick bayonet coupling.
