How much does the Hartford Aero-546BL-5X cost?
Price estimate
We do not have a price for the Hartford Aero-546BL-5X 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-546BL-5X spans 4,600 mm (181.1 in) in Y over a table of 5,000 x 4,100 mm (196.9 x 161.4 in). With 5,000 mm (196.9 in) of X travel it is the widest five-metre gantry type 5-axis machining center in the Aero series.
A cross-beam of that span has to be guided well, and Hartford's description of the structure is specific. The X axis has four linear guideways, two on each side, to maximise rigidity. The Y axis has three. All three linear axes use roller type guideways, which Hartford rates 20 % above ball type for accuracy, load resistance and life.
The work that calls for this width is mostly aerospace and tooling: fuselage frames, wing ribs laid out in nests, lay-up moulds, large models. Such parts are machined with the HSK-A63 spindle, listed here at 18,000 or 24,000 rpm. For heavier tools there is the HSK-A100 at 12,000 rpm.
Z travel is 1,100 mm and can be extended to 1,300 mm. The 5-faced machine of the same size, the Aero-546B, has a #50 gear head at 6,000 rpm and suits steel; the 546BL-5X is the light-alloy and contouring counterpart. Its table is rated at 5,000 kg/m².

Frequently Asked Questions
01
The table is 4,100 mm (161.4 in) wide and 5,000 mm (196.9 in) long, and Y travel is 4,600 mm (181.1 in). Z travel is 1,100 mm, with 1,300 mm as an option.
02
By four linear guideways on the X axis, two on each side, and three on the Y axis. Hartford uses roller type linear guideways on three axes and states a 20 % increase compared with ball type.
03
HSK-A63 at 18,000 or 24,000 rpm, or HSK-A100 at 12,000 rpm. The taper row reads HSK-A63 or HSK-A100, so the choice is made when the machine is ordered.
04
The Aero-546B is the 5-faced model with a #50 gear head at 6,000 rpm and 1,000 mm of Z travel. The Aero-546BL-5X is the 5-axis model with HSK spindles and 1,100 mm of Z. They share the table and the X and Y travels.
