Feeding.
Motorized coil feeder.

Sistema di raddrizzatura del tubo da coil per macchina sagomatrice, curvatubi e segatrice.

Straightening
The tube is straightened by a series of rollers.

Orbital coil-fed tube pre-scoring system

Orbital Cutter
The tube is pre-scored by an orbital cutting device

Flow Drill
Pierce and flow drill.

Endforming
Two different end-forming modules are available. Heavy: up to 6 rams or 4 rams and 1 revolving pass, Light: up to 3 rams or 1 ram and 1 revolving pass.

Bending of tubes from coil with automatic CNC tube bending machine

Bending
Produce fixed radius bends in the plane and variable radius bends freeform, which can be integrated according to the development of the design, all in-process and in automatic sequence.

Cutting on automatic CNC tube bender from a coil

Disc Cutting
Cutting can be performed using orbital or saw cutting devices.

Automatic unloading system for sawing machine and end-forming for coil-fed tubes.

Unloading
The automatic unloading device is fully-integrated into the work cycle and managed by the CNC.

Compression and draw bending

End-forming module

Cutting and piercing

Compression and draw bending

For the best flexibility and productivity, the 4-RUNNER H3 blends compression and draw bending technologies to combine bending speed with the possibility of making short distances between bends and/or between bends and formed ends.

Right-handed and left-handed bends in multi-radius mode

It makes 3D coils or coils with more than one bending radius and parts with extremely complicated geometry.
The low-profile geometry of the 4-RUNNER H1 bending head makes it possible to bend left- and right-handed in-process and multi-radius mode.

Variable radius

Reduce cycle time and create wider, more sophisticated curves with any center line radius.
Variable radius bending offers many advantages, an all-electric system managed by VGP3D is the most precise way to perform it.

Tool change

Quick-change tooling.
Set-up is automatic and there is no manual adjustment required.

Heavy end-forming module

End-forming module with six rams or with four rams and one revolving pass.

End-forming module for tube benders from coil

Light end-forming module

End-forming module with three rams or with one ram and one revolving pass.

Inner orbital cutter

Combining speed and chip-free results.
Inner orbital cutting pre-scores the tube before the bending process. Simply snap of the processed part.

CNC orbital tube bending cutting system from coil

Outer orbital cutter

Maximize versatility by equipping 4-RUNNER with the external orbital cutter.
Ideal when the last straight stretch is very short or the cut is close to the end-forming.
