How much does the Hartford Aero-546B cost?
Price estimate
We do not have a price for the Hartford Aero-546B that we can stand behind, so we show no number. Configuration, options and installation move the final price a long way: a quote is the reliable figure.
Overview
The Hartford Aero-546B is the widest five-metre model of the Aero gantry type 5-faced machining centers. Its table measures 5,000 x 4,100 mm (196.9 x 161.4 in), Y travel is 4,600 mm (181.1 in) and X travel 5,000 mm (196.9 in).
Few machining centers of this length are over four metres wide at the table. The format suits near-square parts: press platens, large mould halves, ring gears and turbine casings, satellite and antenna structures. Since the table is rated at 5,000 kg/m², a part of that size may also be very heavy.
Hartford has a moving-table machine with similar Y travel, the HSA-546AAC, which has 4,600 mm (181.1 in) of Y over a 5,000 x 3,000 mm (196.9 x 118.1 in) table rated for 21,000 kg (46,296 lb) in total. The Aero-546B offers the wider table and the per-area rating.
Spindle and tooling are common to the five-faced Aero models: #50 taper, BT-50 shanks, a gear head at 6,000 rpm with 8,000 rpm optional, and an optional hybrid spindle at 10,000 rpm. Z travel is 1,000 mm, or 1,200 mm. Hartford notes automatic parameter tuning to maintain accuracy, under the heading AI intelligent technology.
