How much does the Hartford HSA-423EA cost?
Price estimate
We do not have a price for the Hartford HSA-423EA 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-423EA pairs 4,000 mm (157.5 in) of X travel with a 2,200 mm wide table and 2,300 mm (90.6 in) of Y. Table size is 4,000 x 2,200 mm (157.5 x 86.6 in) and the load rating 12,000 kg (26,455 lb). It is a five-face double-column machining center with linear guideways.
Of the three four-metre models that carry 12,000 kg, this is the middle one. The HSA-420EA is narrower at 1,800 mm of table width. The HSA-427EA has this table with 2,700 mm (106.3 in) of Y travel. Anyone who needs more weight has to go to the HSA-428EA, rated at 18,000 kg (39,683 lb).
Much of what Hartford says about the machine concerns stiffness: a slant beam, columns joined to the base over a width of 1,250 mm, and a Z axis with four linear guideways. For the drives it lists direct-coupled servo motors on three axes and a nitrogen counterweight on Z, which it credits with halving the hydraulic oil temperature and saving more than 20% energy.
The gear-head spindle runs 6,000 rpm (8,000 rpm optional); the hybrid spindle reaches 10,000 rpm. Both are #50.

Strengths & Limitations
Strengths
- 4,000 x 2,200 mm (157.5 x 86.6 in) table for 12,000 kg (26,455 lb)
- 2,300 mm (90.6 in) Y travel, wider than the HSA-420EA's 2,000 mm (78.7 in)
- Nitrogen counterweight on Z, stated to cut oil temperature by 50%
- Five-face machining through automatic angular heads
Limitations
- Load rating of 12,000 kg is far below the 18,000 kg (39,683 lb) of the HSA-428EA
- Y-axis ballscrew support is an option on x23 models
- Gear-head speed tops out at 8,000 rpm, and that is the optional figure

Frequently Asked Questions
01
Travel of 4,000 mm (157.5 in) in X and 2,300 mm (90.6 in) in Y, with 1,000 mm of Z or 1,200 mm optionally. The table is 4,000 x 2,200 mm (157.5 x 86.6 in) and takes 12,000 kg (26,455 lb).
02
The HSA-428EA, which has a 4,000 x 2,500 mm (157.5 x 98.4 in) table rated for 18,000 kg (39,683 lb) and 2,800 mm (110.2 in) of Y travel. The HSA-423EA is rated for 12,000 kg.
03
It balances the Z axis. Hartford states that the design reduces the operating noise of the hydraulic tank, reduces the oil temperature by 50% and saves more than 20% energy compared with a hydraulic arrangement.
04
The table lists 32 tools as the base figure and gives 40 and 60 as the optional sizes. Shanks are BT-50, or CAT-50, DIN50 or BBT-50 on request, all for the #50 spindle taper.
