4-RUNNER: tube bending and end-forming machine

Complete production process starting from a coil: straightening, end-forming, facing, rolling, bending, cutting and controlled unloading of the finished part all in one.

The unquestionable advantage of this combined machining centre is that it can be configured and used with various modules for specific jobs or complete processes from straightening to unloading the finished parts entirely cut, bent and formed.

On bending side, the 4-RUNNER allows to make fixed and variable radius arrangements on the plane and in space, which can be integrated according to design development in automatic sequences without bending problems: all-in-one process, without reworks.

The possibility of combining multiple radius bending or stretching technologies on the same part guarantees the best flexibility and the highest production rates.

On end-forming side, the machine may be configured with four or six push passes or four push and one revolving pass.

Different cutting devices are used according to applications: inner orbital cutter, outer orbital cutter, disc cutter.

Extreme versatility like this means:

- top flexibility for jobs and applications
- top efficiency and low investments costs with integrated processes and the possibility of implementing just-in-time methods

3D visual graphic programming (VGP3D) makes using the machine extremely easy, comfortable and safe.

The 4-RUNNER bending centre is particularly suited to machining small and medium size tubes even of very complex shapes typically used in automotive, air conditioning, heating or cooling system applications.
