We can supply machines with milling dimensions up to: - daylight between columns: 8 mt. - "X" axis: 48 mt. - vertical daylight: 2,5 mt. The ROVERA G.M. milling-boring machines have some important features, such as: - All the movements are realized using pre-charged linear guides in such a way to guarantee a degree of precision higher than all other hydrostatic machines and above all to assure a constant accuracy under every circumstances. The linear guides grant a very high level of precision and can reach 2 microns/meter. - The "PMF" machines are foreseen with a master fixed column and a transversal "slave" column positioned on roller skids. In such a way the portal frame perfectly fits to the thermal expansions without compromising the precision of the machine. - On each machine it is possible to install the automatic head-changing device. Our models can be conceived for different purposes: from high removal solutions (torque up to 2.000 Nm) to applications with 5 axis electrospindles for machining of aeronautics items and/or moulds. - Several accessories can be supplied, such as rotating tables for turning operations, with a diameter up to 4 meters and capacity up to 60 tons.
