Specialty milling is specifically defined as milling that guarantees a minimum production of 3.5 cu m and a depth precision of ± 5 mm.

Specialty milling stands out from regular milling (removal of one or more layers of concrete or asphalt, either mechanically or by high-pressure water jetting), because it delivers results not achievable using traditional or hydrodemolition systems, including:
With its four patents, the GTF® system is based on machines with very high hydraulic power, structural strength and excellent reliability. Compared to other methods used for milling, such as hydrodemolition or attachments found on the market mounted on regular earthmoving machines, the GTF® system offers significant advantages when it comes to logistics, use of personnel, safety and overall work site costs.
The GTF® system allows significant savings in project completion times. For the most challenging and largest, quantitatively speaking, it can lead to a reduction in completion times measurable in weeks.
When it comes to the cost efficiency analysis (the item that determines the profitability of the work site), the GTF® system always comes out a winner for the power and speed of all machines in the series.
As countless work sites in and outside Italy have proven, the system results in a much faster project execution than other methods using machines and attachments available on the market. Finishing up the job well in advance means being able to start the process of rehabilitating what was milled off and delivering big savings on overall job costs.
The GTF® system is the only one that offers a precision of ± 5mm, another factor that saves time in subsequent profiling operations and when dealing with surfaces that are milled, then applied with grout. Unlike with other methods, hydrodemolition in particular, the precision of the GTF® system in this case – even when milling long sections – enables an advanced calculation with a minimal margin of error of the amount of grout to be used.
During design of the system, great efforts were made to guarantee reliability and productivity. That’s because we were aware that, especially in tunnels, all components are subject to significant wear and stresses (vibrations, high temperatures, dust, etc.), making these two characteristics a top priority. Strenuous tests and, above all, the many jobs completed successfully both in and outside Italy have proven us right.
Safety is another aspect where the GTF® system shows its solid advantages: the operator is not exposed to possible risks related to the site or operation of the machine, since a sophisticated radio allows them to remote control the machine and, if necessary, monitor the work in progress via a high resolution video system installed in an equipped van.
