How much does the Hartford HSA-628EA cost?
Price estimate
We do not have a price for the Hartford HSA-628EA 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
Six metres of X travel and a 23,000 kg (50,705 lb) table: the Hartford HSA-628EA is the narrow six-metre model of the five-face HSA line. Its table is 6,000 x 2,500 mm (236.2 x 98.4 in) with twenty-three T-slots, X travel is 6,000 mm (236.2 in) and Y travel 2,800 mm (110.2 in).
Above five metres Hartford makes X-axis ballscrew support standard, and this is the first EA size to which that statement applies without doubt. A six-metre screw is heavy, and supporting it limits sag and protects both positioning accuracy and the screw.
Only two EA models exist at this length. The other, the HSA-636EA, has a 6,000 x 3,000 mm (236.2 x 118.1 in) table and 3,600 mm (141.7 in) of Y but adds just 1,000 kg of capacity. For long parts that stay inside 2,500 mm of width, such as machine beds, crane girder sections and extrusion tooling, the 628EA does the same job on a narrower machine.
The table for this model lists a hybrid built-in spindle at 10,000 rpm and a gear head at 6,000 rpm with an 8,000 rpm option, in #50 taper. Hartford's page adds DDS as a spindle choice. Z travel is 1,000 mm, optionally 1,200 mm.
