Insulation with panelling protects the most heat-sensitive structures such as the bridge and the RAM
The right solution for preventing structure deformations
Exposure of a section of the machine or the entire machine to thermal shock can greatly impair its performance. Breton devised the patented Thermal Shield system, which makes it possible to protect machine structures from sudden temperature changes or gradients due to ambient temperature changes.

- More accuracy1
With Thermal Shield narrow tolerances can be complied with more easily.
- Improved finish quality2
Improved finish quality
The finish quality eliminates gaps between passes and reworking to correct deformations.
- Guaranteed repeatability3
Avoiding deformations allows the machine to rework the parts in time, maintaining high levels of precision.
- Same temperature for the machine and workpieces4
Same temperature for the machine and workpieces
Non essendo un sistema di raffreddamento, la temperatura della macchina è molto più vicina a quella del pezzo da lavorare - a garanzia di tolleranze dimensionali ideali.
- Simple and effective5
Simple and effective
Since it is based on a simple but effective concept, it leaves no room for malfunctions and guarantees certainty of performance.
Preventing deformation caused by temperature changes
The parts exposed to the heat sources experience a more abrupt temperature change than the rest of the machine, thus creating stress in the structures with consequent geometrical deformations.
The ThermalShield system protects structures from sudden temperature changes thanks to the use of two technological solutions:
- Structural insulation by means of panels means temperature changes of machine parts are greatly reduced (approximately 1/5) and far slower than in surrounding areas.
- A closed circuit internal ventilation system of unit structures that allows temperature uniformity with differences in the order of a few tenths of a degree.
Combining these two technologies allows the machine structures to adapt to temperature changes uniformly, reducing torsional deformation effects and transforming them into linear deformations that can be controlled by means of compensation techniques.
Why the Thermal Shield is essential
- / 01Insulation of the main structures
Each part of the structure has an internal ventilation system to standardise the temperature and keep the structure thermally stable/ 02Controlled ventilation
The system is passive using just a few Watts of power for the fans: reduced energy consumption/ 03Sustainable
There are no complicated cooling systems subject to the risk of faults/ 04Less is more
