GTF machines offer a full range of models with a wide and modular work envelope. Thanks to the wide range of Ram and milling heads, the GTF machines always have the best fit application for various fields: Automotive ■ Aerospace ■ General Machining General Machining Thanks to the modular design it is now possible to utilize FIDIA technology to produce large size mechanical components. A typical example is the wind-turbine power generator, from the blade forming mold to the gear and its casing. Energy as well as Naval or Rail industries sometimes require very accurate machining cases, which...

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 superfinishing. 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 These type of molds require precision in details and high surface quality. The unique design of...

Bi-rotary head M5E The rapid system change of heads and spindles widely extends GTF effectiveness in the automotive, aerospace and general machining heavy duty applications. The M5E head and relevant Ram solution up to 2500 mm Z stroke offers 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. Max. spindle speed Continuous max. power Toolholder

M5A and M5C heads enhance the high speed cutting performance and fit over most GTF applications; thanks to their compact structures easy tool access to the narrowest areas of the parts can be reached. The M5A milling head is built around a cast iron structure meant to deliver stiffness and thermal stability during demanding operations on steel as well as aluminum. The M5C is a lighter version of M5A, made with aluminum alloy. This model does not require hydraulic clamping since it aims to cut lighter materials such as aluminum, composite, clay and resin.

Working volume cover Double tool change Epoxy concrete columns

Made of stiff epoxy concrete columns to allow the best vibration dampening effect, these versions of GTF family have the greatest level of modularity, thanks also to the 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 600 x 600 mm ram allows wide range of heads to choose from: QQM5S, M5S2, M5D, M5E QQM5H with strokes up to with Z strokes from 1000 up to 2500 mm 2000 mm The axes kinematic chains may vary in order to achieve the highest working speed and acceleration....

Chip Conveyor

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 allows for high dynamic 5 axis interpolation and accurate results. Structures are made of welded steel and concrete walls to match a wide Z clearance requirement. X Strokes Axis speed Load capacity Milling Head Y2G A double cross beam 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....
