The main characteristics of the MG Line are:
• working volume from 6.25 m³ to 46.5 m³
• maximum volumetric precision thanks to the morphology of the bridge with moving table
• load capacity on the worktable from 10t to 30t
• high positioning accuracy
• easy loading and clamping of the pieces
• comfortable position for the operator with excellent visibility of the cutting area
• high capacity of stock removal, removal on steel >1000 cm³/min
• optimal vibration damping
• possibility of automatic operating head changing
Structural stiffness
The bases and the column are widely dimensioned to support high cutting forces and for an optimal vibrations damping.
Thermal control
The main heat sources are kept at a controlled temperature. The mechanical spindles, heads and gearboxes are cooled by oil, the electro-spindle with water.
Very high stiffness and accuracy

The RAMMATIC line version has been developed for the profiling of special aluminum alloys, steel and titanium used in the aerospace industry. The tilting head is the emblematic element of this machine.
Line RAMMATIC is characterized by:
• removal capacity independent from the position of the cross axis
• optimized geometry and not influenced by the position of the cross axis
• head with axes A and B with very high rigidity
• high removal capacity
• high volumetric accuracy static and dynamic
• optimum view of the cutting area
• completeness of equipment and accessories
Structural stiffness
The bases and the column are widely dimensioned to support high cutting forces and for an optimal vibrations
damping.
The double tilting head can use both mechanical spindle with high torque with 2 speed gearbox and a high power electro spindle. The mechanical spindle and the electro spindle are cooled in order to ensure thermal stability.
The DTH head with double tilting is used to allow the continuous profiling without the tool disconnection during the machining operations to Tool always in contact with the workpiece
