Modularity The upper Gantry GTF line is characterized by great versatility. Thanks to its modular structure, and taking advantage from a combination of components conveniently selected according to weight, stiffness and cost requirements, the GTF range becomes an ideal solution to fulfill all Customers’ demand. Performances The harmonious sizing of its structures in accordance with the thermo-symmetry concept, perfectly matches with the extremely dynamic linear axes. Rack & pinions driven by double motors and variable preload grants for total absence of backlash. Fidia technology inside The FIDIA...

Applications GTF machines offer a full range of models with a wide and modular work envelope. Thanks to the wide choice of Ram and milling heads solution, GTF always find the best fitting application in various fields: Automotive JJAerospace jGeneral Machining Aerospace High accuracy and efficiency in 5 axis machining is essential for operating on many types of aeronautical and aerospace structural components. GTF has specifically designed solutions to afford machining of each material utilized in aerospace: ALUMINIUM, TITANIUM, COMPOSITE MATERIALS require chip conveying systems with filtering...

Automotive Stamping dies The automotive industry requires powerful and highly accurate machines to mill cast-iron and steel dies from the roughing operation to the final super-finishing thanks to GTF's fixed table-upper gantry configuration, manual polishing can be mostly avoided and all operations can be done with a single set up of the workpiece. The most difficult areas of the component are attained by an appropriate choice of heads and milling accessories. Plastic injection and die-casting This type of moulds pursues either precision in details and high surface quality. The unique design...

In any FIDIA's head, the A and C axes performs high dynamic continuous interpolation as well as the 3+2 positioning mode. During a full 5 axes machining, the rotative axes (A,C or both) can be stiffly clamped by means of powerful hydraulic brakes, exploiting the maximum torque of the spindle. The axes cinematic chain is provided with life-time automatic backlash recovery and is able to perform 0.001° resolution positioning. M5A and M5C heads enhance the high speed cutting performance and fit over most GTF applications; thanks to their compact structures a easy tool access to the narrowest areas...

The rapid system change of heads and spindles widely extends GTF effectiveness in the Automotive, Aerospace and General Machining heavy duty applications. REPOSSINI M5E head and relevant Ram solution up to 1850 mm Z stroke offer roughing capacity together with high speed on cast iron, steel and tough materials. M5E quick change cartridge system allows for the use of different kinds of electrospindles. M5H head with mechanical spindle unit develops high torque and integrates automatic accessories change to allow for access into narrow spaces. The dedicated reinforced Ram and multi guide-ways system...

GTF/R Made of stiff Epoxy Concrete columns, to grant for the best vibration damping effect, these versions of GTF family have the greatest level of modularity, thanks also an automatic heads changing system. Starting from the smallest 2+2 columns configuration, the same design can be extended to any X axis length just by adding columns. The GTF/R integrates a 600 x 600 mm ram. Consequently, this version offer a wide range of heads to choose from: M5A with Z strokes from 1000 up to 2500 mm (GTF/RA) J M5D with stokes up to 1850 mm (GTF/RD) J M5E with strokes up to 1850 mm (GTF/RE) J M5H with strokes...

GTF/L The lightest version of GTF family is particularily suitable for complex aluminum or composite parts and 1:1 Automotive styling models. Thanks to the specific M5C head, the machine grants for high dynamic 5 axis interpolation and accurate results. Structures are made of welded steel plus concrete walls to match a wide Z clearance requirement. X Strokes Axis speed Y2G A double traverse version called Y2G further enhances the modular concept of the GTF machine. Two independent heads can work either sharing the same piece or two different pieces using the bulkhead. The X-axis stroke can be...

GTF/Q The modular version Q is based upon compact columns and traverse optimizing floor space in the workshop. The Epoxy concrete structure of columns preserves geometry and accuracy from thermal effects. The innovative design of traverse makes it suitable for all versions of M5A and bi-swivelling heads. It’s equipped with ram up to 1400 mm stroke.
