Infinity 22

Versatility over the structural limits

News for Cutting Expanded Polystyrene

Completely re-designed and renewed, the brand new INFINITY22 arrives at Nettuno.

Developed by our team of engineers and technicians , this machine was born starting from the model Infinity , on the market since 2008 and still now the spearhead of the Nettuno house.

With the adaptable structure and the possibility to adjust the length of the cutting wire, this machine has totally changed the modus operandi of all the operators and companies processing Expanded and Extruded Polystyrene (EPS / XPS ).

Following the concept of this glorious model, the new Infinity22, brings along years of experience and successes , which make it the most advanced and performing CNC hot wire foam cutting machine available in the global market.

All the news:

· The heavy duty structure totally made of steel plus flattened and router milled profiles is made in order to increase the precision of the machine and hold the weight of full Styrofoam blocks with any density.

· The length of the cutting wire (adjustable from 1000 mm up to 4100 mm) is now set from the software and the machine automatically moves into position, without any manual adjustment by the operator

· The new brushless servomotors with absolute encoder of the 4 independent axes, move on bearing screws and gear racks, which replace the toothed belts for the transmission.

Also the software for cutting and projects development, Nettuno Docker Cam, already appreciated for the user-friendly interface and the advanced applications for cutting eps / xps in 2D and 3D , has been further updated with new graphics and applications.

With the wireless Handheld Keypad Nettuno is possible to do different operations:

  • STO

All of these operations can be done staying close to the cutting wire while you still control the machine from remote, not using the main control (power station).
Useful when you need to execute manual moving and cuts of foam blocks

Machine cutting area

Thanks to its structure, which is fluid and slides on rails, it is possible to increase the cutting area of the Infinity22.
This allows to make cuts of 4 meters. The machine can quickly switch from industrial work cycles to settings for making accurate cuts. The versatility of the Infinity22 allows it to change wire diameters from 0.20mm to 0.50mm. Even detailed and accurate cuts on delicate work pieces of even very small dimensions are within CNC reach.

Multiple movable tabletops

To load the block of expanded polystyrene has never been so easy.
Thanks to the 4 movable tabletops of the machine, is it enough to move them on its recirculating ball bearing guides, running on rails, in order to load a new foam block quickly and easily. In addition, the cutting process with Shapeable Wire will be easily executed, even if the block of Styrofoam has large dimensions. The stratified tabletop is smooth and perfectly leveled and allows cutting even small shapes having always the top precision.

Adaptable structure

The structure of Infinity 22 can be rapidly extended because it runs on accurate rails fixed on the ground. For this reason, it is possible to cut blocks of expanded polystyrene long up to 4.200 mm. (Infinity22 can be customized upon request to cut eps blocks long up to 5.000 mm)
Infinity22 can so be adapted for processing shapes of large dimensions or alternatively very small shapes with fine details. The versatility of Infinity22 allows installing cutting wire of different diameters: 0.20, 0.25, 0.30, 0.40, 0.50 mm. Working with Infinity22 is the same as if you have more than one cnc foam cutter, because it can be adapted for any kind of cutting process for the expanded polystyrene.

Automatic wire tension system

Infinity 22 is equipped with an advanced “automatic wire tensioner” developed from Nettuno Sistemi after years of research, that has been poorly copied by competitors worldwide.
The pc controlled Tensioner Nettuno allows the cutting wire to reach the maximum inclination between the axes without any limitation for foam conical / tapered cuts.
It is equipped with a spool of wire that is being pulled or released, during cutting process with independent axes, always keeping constant the tension of the wire, having the best cutting accuracy.

Cutting Wire Inclination

Reducing the dimension of the main structure of the machine, thanks to its rails fixed on the ground, you can get a higher wire inclination than a machine having fixed structure.
Therefore, thanks to the high angle of inclination, same to the diagonal of the system is possible to cut such particular conical and tapered eps shapes that with a standard machine you could not get.

Microprocessor to control the wire temperature

The temperature of the cutting wire is pc controlled. In this way, you will be sure to have always the correct wire temperature as you set before starting cutting the foam block. It will maintain the wire temperature at the same value also in case of sudden change in tension or change of wire length because of the automatic wire tensioning system.

Multiple Wire Version

The Multiwire version of Infinity 22 can cut a foam block simultaneously with more than one wire ( you can set it from 1 up to 20 cutting wires), processing in series multiples pieces of the same shape, with just one moving of the harp through the foam block. The MultiWire version can also work with a single wire, just removing the harp in an easy and quick way. The cutting wires, when operating with multiwire harp, are tensioned by springs, but once the harp is removed, the automatic tensioner Nettuno regulates the wire tension.
Cutting with the Multiwire system gives different advantages:

  • Reduction of production time
  • Reduction of production cost
  • Increase of productivity

Recommended for the production in series of same profiles, this system is mostly used for making cornices, parapets, architectural foam decorations, mouldings ,insulation boards and panels of eps / xps (used for the external wall insulation system – EIFS), insulated shutter box, packaging, etc.
Infinity 22 Multwire can be equipped with 20 cutting wires 2500 mm long.

The distance between the wires is adjusted manually along a metric scale.

The harp of the Multiwire System that can work in vertical, horizontal or oblique position becomes necessary for the companies who need to produce large number of the same foam shapes.

particolare multiwire clevel

High Precision Transmission for X and Y axes.

Closed loop Stepper motors don’t run on standard Belts, but the motors on X-X1 run on Gear Racks and Y-Y1 axes run on Bearing Screws.

As result the machine increase its precision of cuts.


The intelligent cutting wire speed system.
Clevel is an automatic feed rate adjustment, (conceived and patented by Nettuno Sistemi), that can automatically adjust the feed rate (cutting speed) of the axes by detecting the alignment of the cutting wire.
It can regulate and optimize the speed of cutting wire in relation of the different density of the foam that the machine is cutting.
To set manually the correct cutting speed for the cnc foam cutter could be complex procedure and the operator must keep in mind different parameters:

  • Cutting wire temperature
  • Diameter of the cutting wire
  • Temperature of the environment where the machine is placed
  • Environmental humidity
  • Humidity of the expanded polystyrene block that he is going to cut
  • Density of the Styrofoam block
  • Possible irregular expansion of the foam block

Clevel is able to process all these data automatically and in real time.

Installing Clevel on the CNC hotwire foam cutters Nettuno Sistemi, the operator is avoiding mistakes and low accuracy of the cuts, that could happen when the foam cutting machine works without a preliminary control of the above mentioned parameters and a continuous monitoring of the cutting process.


The technology hotwire cutting system of Nettuno Sistemi is based on patented software applications..

Nettuno believes and pursuits a continuous development of user-friendly software interface.

The software Nettuno Sistemi, for our hotwire CNC foam cutting machines, is divided in two different applications

  • Nettuno Plug-in, CAM integrated with Corel Draw (for creating 2D and 3D models / drawings)
  • Nettuno Cutter, interface directly connected with the machine for making 3D cutting simulation and execute the cuts.
