How much does the Hartford HSA-628 cost?
Price estimate
We do not have a price for the Hartford HSA-628 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 HSA-628 carries 23,000 kg (50,705 lb) on a 6,000 x 2,500 mm (236.2 x 98.4 in) table. This double-column machining center has 6,000 mm (236.2 in) of X travel and 2,800 mm (110.2 in) of Y, on linear guideways throughout.
The comparison that matters at six metres is with Hartford's own alternatives. The box-way SW-626 has the same table and is rated for 16,500 kg (36,376 lb). The moving-crossbeam MW-633 adds a W axis and automatic heads on a 2,200 mm wide table. The HSA-628 is the plain, fast, high-capacity option: a fixed cross-beam, a table on three linear guideways and a choice of three spindle drives.
Those drives are a #50 gear head at 6,000 / 8,000 rpm, a DDS spindle at 10,000 / 12,000 rpm and a built-in spindle at 12,000 rpm. Motors run from 15 / 18.5 kW through 18.5 / 22 kW and 22 / 26 kW to 30 /37 kW.
Z travel is 780 mm with 1,000 mm and 1,200 mm as options. Hartford's slant cross-beam is intended to reduce vibration and improve surface finish, and the nitrogen-counterweighted ram runs on four linear guideways. The tool magazine starts at 32 tools; 40 and 60 are listed.

Strengths & Limitations
Strengths
- 23,000 kg (50,705 lb) table load on a 6,000 x 2,500 mm (236.2 x 98.4 in) table
- Three X-axis linear guideways and a supported X ballscrew
- More load capacity than the box-way SW-626 on the same table size
- Three #50 spindle drives up to 12,000 rpm
- Motor options to 30 /37 kW
Limitations
- Fixed cross-beam: no W axis, unlike the MW-633
- Y travel of 2,800 mm (110.2 in) gives little room beside a 2,500 mm table for angle heads
- Standard Z travel of 780 mm
- No published rapid traverse rates
