How much does the Hartford Aero-636B cost?
Price estimate
We do not have a price for the Hartford Aero-636B 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-636B is a six-metre gantry type 5-faced machining center with a 6,000 x 3,100 mm (236.2 x 122.0 in) table, 6,000 mm (236.2 in) of X travel and 3,600 mm (141.7 in) of Y travel. Among the four B models at this length it is the second narrowest.
Its closest relative is not a B model at all. The Aero-631G has the identical table but only 3,100 mm (122.0 in) of Y, so its spindle stops at the table edge. On the 636B the Y axis runs past the table on both sides, and that is what lets an angular head work down the long flanks of a part as wide as the table. For true five-face machining of full-size parts, this is the one of the pair to choose.
Hartford offers an optional spindle that it makes itself, the i-Tech hybrid, at 10,000 rpm. It is described with a double cooling cycle design, one circuit for the motor and one for the spindle, and a built-in motor rated at a maximum of 35 kW and 600 N-m. The standard spindle is a #50 gear head at 6,000 rpm, or 8,000 rpm as an option.
The table is rated at 5,000 kg/m². Z travel is 1,000 mm, with 1,200 mm optional, on four linear guideways.
