Nettuno Sistemi Mammut

Cutting Expanded Polystyrene Gets an Upgrade!

Introducing the all-new MAMMUT, a complete re-design and renewal of our renowned INFINITY model, which has been the flagship of Nettuno since 2008.

With its adaptable structure and adjustable cutting wire length, Mammut revolutionizes the operations of operators and companies working with Expanded and Extruded Polystyrene (EPS / XPS).

Building on the success of its predecessor, Mammut comes with years of experience, making it the most advanced and high-performing CNC hot wire foam cutting machine in the global market. Furthermore, our cutting and project development software, Nettuno Docker Cam, has received updates with new graphics and advanced applications. It continues to offer a user-friendly interface for cutting EPS / XPS in 2D and 3D. Experience the cutting-edge capabilities of Mammut as it sets new standards in the foam cutting industry.

What you can make

The versatile CNC hot-wire foam cutting machine Mammut for polystyrene cutting is perfect for various cutting needs, handling both large and small detailed shapes with precision. It allows production of intricate 3D foam letters, logos, signs, and decorated EPS cornices/parapets. Moreover, it can create prototypes or large shapes for the industrial sector, including polystyrene panels, sheets, external insulating boards, moldings, precast elements, insulated shutter-boxes, roof insulation boards, decorative elements, swimming pool designs and components, packaging boxes or protections, movie set pieces, scenography, and spa/sauna beds and seats.

Processable Foam

• EPS (Expanded Polystyrene)
• XPS (Extruded Polystyrene)
• Rigid foam

Machine cutting area

The fluid sliding on rails structure of the CNC hot-wire foam cutting machine Mammut enables an expanded cutting area, allowing for 4-meter cuts. This machine easily transitions from industrial work cycles to precision settings for accurate cuts. The Mammut’s versatility allows it to switch between wire diameters, ranging from 0.25 to 0.50 mm. It can handle detailed and precise cuts, even on delicate work-pieces of very small dimensions, all achievable through CNC capabilities.

Multiple movable table tops

Loading the expanded polystyrene block has never been easier. The machine’s 4 movable table tops can be effortlessly moved on their recirculating ball bearing guides, gliding along rails, facilitating the quick and easy loading of a new foam block. The table tops have a pneumatic lock on guides and are perfectly leveled, enabling precise cutting of even small shapes with utmost accuracy.

Adaptable structure

The structure of this CNC hot-wire machine can be easily extended due to its accurate rails fixed on the ground, enabling the cutting of expanded polystyrene blocks up to 4500 mm long. Upon request, Mammut can be customized to cut EPS blocks up to 6000 mm long. This adaptability makes Mammut suitable for processing both large and small foam shapes with intricate details. Its versatility allows the installation of cutting wires with different diameters, ranging from 0.25 to 0.50 mm. Working with Mammut is akin to having multiple CNC foam cutters, as it can be adapted for various cutting processes for expanded polystyrene.

Automatic wire tension system

The CNC hot-wire foam cutting machine Mammut features an advanced “automatic wire tensioner,” a product of Nettuno Sistemi’s extensive research, which has been unsuccessfully imitated by competitors worldwide. The PC-controlled Tensioner Nettuno enables the cutting wire to achieve the maximum inclination between the axes, without any restrictions, making it ideal for foam conical/tapered cuts. Equipped with a wire spool, the tensioner adjusts the wire tension continuously during the cutting process with independent axes, ensuring consistent tension and providing the utmost cutting accuracy.

Cutting Wire Inclination

By reducing the dimensions of the main structure and using fixed rails on the ground, the machine achieves a higher wire inclination compared to machines with a fixed structure. This high angle of inclination, equivalent to the diagonal of the system, allows for cutting unique conical and tapered EPS shapes that would be challenging to achieve with a standard machine. The increased wire inclination offers greater flexibility and precision during the cutting process, enabling the creation of intricate and specialized foam designs.

CNC Router

The 3-axis CNC milling router is capable of working on a plane or in combination with the horizontal lathe. By utilizing the rotation of the horizontal lathe and the movement on 3 axes of the router, 360° machining on the material can be achieved.
The automated system developed by Nettuno provides the opportunity to attach the accessory directly onto the machine by issuing simple commands from the software. The operator can conduct wire-based turnings for roughing the material and then complete the final details using the CNC milling machine. This ensures a significant advantage in execution times and the realization of 3D shapes.

Multiple Wire Harp

The multiple wire version of the CNC hot-wire foam cutting machine Mammut for polystyrene cutting allows for simultaneous cutting of a foam block with multiple wires (from 1 to 20 cutting wires each measuring 3100 mm in length), efficiently processing multiple pieces of the same shape in series with just one harp movement through the foam block. It can also work with a single wire by easily removing the harp. The cutting wires are tensioned by springs when operating with the multiple wire harp, and once the harp is removed, the automatic tensioner Nettuno regulates the wire tension.

Main Rotating Table

The innovative and exclusive system allows for the automatic rotation of an entire block of expanded polystyrene with a length of up to 3000 mm, enabling cutting on all 4 sides of the block.The rotation of the main machine table occurs completely automatically and is managed by the software interface.

This system is highly advantageous for the production of styrofoam shapes and profiles that require cuts and grooves on more than one side. The rotating table can also work in combination with the multi-wire system to increase productivity and the machine’s efficiency.

Clevel

The intelligent cutting wire speed system, Clevel, is an automatic feed rate adjustment that detects the alignment of the cutting wire and adjust the feed rate of the axes accordingly. It optimizes the cutting wire speed based on the foam’s different densities being cut by the machine.

Clevel processes all these data automatically and in real-time. This ensures a more precise cutting process, avoiding inaccuracies that may occur when the foam cutting machine operates without preliminary control of the mentioned parameters and continuous monitoring of the cutting process.

Vertical Turntable

The vertical lathe, controlled through the machine’s software, is used for 3D turning and forming. The EPS block/cylinder is placed vertically, and it can be used incombination with the shapeable wire carver to shape columns or capitals. There is also the possibility of adding 1 to 3 vertical lathes for increased flexibility and productivity.

Carver

The carver utilizes a rigid wire, manually shaped to create recesses within pre-formed designs. It can be used in combination with the vertical or horizontallathe to create intricate features such as spiral columns.

Horizontal Lathe

This optional software-controlled lathe allows shaping the polystyrene block into 3D forms. The block/cylinder is positioned horizontally and cut 360°. It can be used incombination with the shapeable wire carver to create grooves along the surface of the column.

Extra Tabletops

The basic configuration includes 4 sturdy support tables, carefully crafted to ensure maximum stability and precision during the cutting operation. However, recognizing the importance of adapting our product to specific needs, we offer a customization option that allows adding from 1 to 3 additional support tables.

Versatile

What makes Mammut special is its versatility, allowing for a wide range of applications. With its dynamic and adaptable structure (Z axes – wire length – can be adjusted from 1050 to 4500 mm), it can accommodate wires with different diameters (0.20 to 0.60 mm). This enables cutting both small, intricate foam shapes and large, industrial applications with the highest accuracy.

Accurate

The combination of a structure made with robust steel profiles and axes running on gear racks and bearing screws results in the most precise CNC foam-cutting machine available in the market.

Easy to use

The operator can easily execute complex cuts using the advanced and intuitive software from Nettuno Sistemi. It efficiently manages all the different steps of the foam cutting process, making it simple and user-friendly.
