Clevel

The cutting wire becomes intelligent!

Clevel is an automatic wire speed adjustment system, created and patented by Nettuno Sistemi.

The adjustment is managed based on the type of material encountered. Choosing the correct speed is a complex operation that must take into account several variables, including:

Wire temperature
Wire section
Ambient temperature
Ambient humidity
Material humidity
Material density
Non-uniform material expansion

Clevel handles all of this completely automatically and in real-time.
By installing Clevel on Nettuno machines, errors, inaccuracies, and defects resulting from cutting at an inadequate speed, determined through specific checks and continuously monitored, are avoided.
With Clevel, you can easily benefit from:

No longer needing to continuously monitor various stages of the processing. The operator will no longer have to periodically check the wire’s activity inside the material.

Cutting Speed

Very often, it is mistakenly believed that the cutting speed of the machine is solely related to the hardware characteristics of the pantograph, but that is not the case.

The maximum cutting speed of the machine depends on numerous factors not directly attributable to the pantograph’s features.

Our machines are equipped with motors capable of working at speeds of 10,000-15,000 mm/min. However, the maximum speed is determined by factors such as:

Material density: The higher the density, the lower the cutting speed. For instance, with a low-density polystyrene block (10-15 kg/m3), the pantograph can cut at a speed ranging from 1,000 to 1,500 mm/min. If the EPS density is very high (30-35 kg/m3), the pantograph will need to be set at a lower cutting speed, around 400-500 mm/min.
Polystyrene seasoning: Two blocks of polystyrene with the same density can exhibit different cutting resistance depending on their seasoning.
Block and ambient humidity: The humidity of the block and the cutting environment also influence the cutting speed.
Wire material: The type of wire used is another variable to consider in determining the correct machine speed. Nickel Chrome or Titanium wires can be used for polystyrene cutting. Titanium wire offers better precision and strength, allowing for a higher cutting speed compared to Nickel Chrome wire.

In addition to the mentioned variables, differences in consistency and/or humidity can be observed within the same block. It is not uncommon for the outer part of the polystyrene block to be drier while the central part is slightly damp. Furthermore, the density may vary due to imperfectly homogeneous extrusion/expansion of the block.

Nettuno Sistemi has endeavored to study a solution for their pantographs that ensures optimizing the cutting speed, taking into consideration all these variables.
