Fidia GTF/R

The Fidia GTF/R is the heavy, most modular member of the GTF gantry family, built on epoxy concrete columns with a 600 x 600 mm ram. X travel is listed at 5,200 mm (205 in), 7,600 mm (299 in), 10,000 mm (394 in), 12,400 mm (488 in) or 19,600 mm (772 in), and Fidia says the design can be extended to any X length by adding columns to the smallest 2+2 columns configuration.

Y comes in four widths: 2,200 mm (87 in), 3,500 mm (138 in), 4,000 mm (157 in) or 5,000 mm (197 in). Z runs from 1,000 mm (39 in) to 2,500 mm (99 in). Table load capacity is 9,000 kg/m² (1,843 lbs/sqft), the figure that marks this as the version for large steel and cast iron dies.

The large ram exists to carry a wide choice of heads, with automatic head changing. Fidia lists the M5A/55 continuous head with 55 kW, the M5S symmetrical head with 65 kW, the M5E orthogonal head with an interchangeable spindle, and the M5H, a mechanically driven high-torque head given as 1,100 Nm and 34 kW. The specification table itself says speed until 30,000 1/min and torque up to 1,000 Nm, so ask Fidia which torque figure applies to the head you need.

Standard axis speed is 30 m/min, with 50 m/min in X and Y and 40 m/min in Z as an option. X and Y are driven by tandem rack and pinion. Where lighter work dominates, the GTF/L runs X and Y at 60 m/min. Where a double gantry is wanted, see the Y2G/Q4.
