Reinforced structure and precision mechanics recirculating ball bearing guides

The structure of the machine Series Professional has been designed and developed for being strong and steady during all the steps of cutting process and configured for support extra tools / optional.
All of the hotwire cnc foam-cutting machines of Professional Series can be equipped with Shapeable Wire, Horizontal Turntable, Vertical Turntable / Rotating plate and Clevel.
Wireless Handheld keypad and pc controlled wire tensioner are included also in the basic version.
It is available for 120Pbox, 400i and 800i the configuration with Multiwire even stonger than standard version.
The axes run along linear recirculating ball bearing guides for a high precision and fluidity of moving.

Pc-controlled wire tensioner

The tension of the cutting wire for the Professional Series is regulated by use of the advanced tensioning system pc controlled developed by Nettuno Sistemi.
This unconventional pc-controlled tensioner (not pneumatic) was first conceived by Nettuno Sistemi and then barely copied by competitors worldwide.
It allows getting then maximum diagonal of the cutting wire when processing files with independent axes.
The tensioner is equipped with a spool or wire and during the execution of the cut, is able to recognize when to release or pull back the wire, always keeping constant the tension of the cutting wire.
Contrary to what happen when the tension is regulated by springs that can lose force after a while and affect the accuracy, with the tensioner Nettuno you are sure to get the highest precision.

Table Top made of Stratified Glass.

Nettuno Sistemi has decided to use a tabletop made of stratified glass in order to have a linear and smooth surface where to place the foam blocks or panels.
This can support the expanded polystyrene and the operator is able to cut also small foam shapes.
Furthermore, the tabletop allows the cutting wire to get the base of the foam block, detaching completely the shape from the block.
The technical features and properties of the stratified glass assure a long life of the table top.

Optional and extra tools

All of the cnc foam cutters of the Series Professional include


The hotwire foam cutting machines 120pbox, 400i and 800i are 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 Wire Tensioner Nettuno allows the cutting wire to reach the maximum inclination between the axes without any limitation for foam conical/tapered cuts.
A spool releases and pulls the cutting wire, during cutting process with independent axes, always keeping constant the tension of the wire, having the best cutting accuracy.


All the cnc foam cutters of the professional Series are equipped with the new wireless Handheld Keypad Nettuno that is used by the operator for different operations:
All of these operations are executed 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.


particolare multiwire clevel


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.

Horizontal Lathe

Horizontal Turntable/Lathe, is used for to processing large 3d Styrofoam shapes or sculptures starting from long eps blocks and / or foam cylinders.
This tool is able to cut complex expanded polystyrene spiral columns, fluted columns, twisted columns, capitals and many 3d objects also combining it with the shapeable wire.
The main difference between vertical turntable and horizontal lathe, is that you can process longer foam block because it can cut blocks all along the same length of the X axes.

Vertical Turntable

The Vertical Turntable, also called rotating table, is an optional used for cutting 3D foam shapes, symmetrical or asymmetrical irregular, spheres, columns, 3D foam characters and figures. This optional, can be also combines with the Shapeable Wire for making grooves on 3D Styrofoam shapes. (like details on coke bottles)

Shapeable wire

Using the shapeable wire it will be very easy to make foam shapes with grooves or engraves.
The shapeable wire / carver is installed, on the slider of the CNC foam cutter and moves following the path drawn in CAD.
Using brass clamp, a shaped Nickel Crome wire is fixed on the machine and then cut the expanded polystyrene.
The combination between the handcraft accuracy and the technology CNC is giving as result unique curved models that a standard straight cutting wire, could not give.
This tool is used for creating foam moulding and decorations like capitals, foam columns, pillars, parapets, crowns and much more.
The cutting process joined with Vertical or Horizontal turntable allows making great decorated foam twisted columns.


Multiple Wire Version *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 foam shape, with just one moving of the harp through the EPS block.
The Multi Wire version can also work with a single wire, just removing the harp.
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.

The cnc hotwire cutting machine with multiple wires have a reinforced structure too. The Y axes are driven by bearing screws (not belts) and the motors are stronger than standard version.

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 / panels / slabs of eps / xps (used for the external wall insulation system – EIFS), insulated shutter box, packaging, etc.

The length of the wires is:
1300 mm for 120pbox
2300 mm for 400i

The distance between the wires is set by hand 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.

*not available for 800i
