Fidia Go5

The Fidia Go5 is a compact 5-axis high-speed milling centre with a fixed gantry and a moving, tilting rotary table. Axis strokes are 600 mm (23.6 in) in X, 850 mm (33.5 in) in Y and 450 mm (18 in) in Z. The table plate is Ø400 (15.7 in) and carries up to 300 kg (660 lb). Y is the long axis here, so the envelope is deeper than it is wide.

The structure is the main argument. Fidia builds it entirely from cast iron on a 45° inclined base, which carries the tilting rotary table and lets chips fall toward the front auger and rear conveyor that come as standard. At approximately 8,000 kg (17,637 lb) the monoblock is levelled on anti-vibration mounts and, by the maker's account, needs no special foundation. That matters to a shop that cannot cut a pit or may move the machine later.

Two spindles are offered, and they pull the machine in different directions. The M3A/20-18 on HSK-A63 is the roughing choice, rated 11.7/20 kW and 26/80 Nm (S1/S6). The M3A/19-36 on HSK-E50 trades torque for small-tool finishing, with 17/19.5 kW and 11/12.5 Nm (S1/S6). HSK-E50 holders are a different family from HSK-A63, so the spindle decision also fixes the tool inventory.

The B axis tilts the table ±180° and C turns 360° (continuous), with the linear axes at 30 m/min. The 300 kg (660 lb) limit and the 15.7 in plate define the part size more tightly than the strokes do: electrodes, inserts and small moulds rather than die blocks. For larger 5-axis work, the Go9 has a Ø 800 mm (31.5 in) table.
