How much does the Hartford SW-623 cost?
Price estimate
We do not have a price for the Hartford SW-623 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
At 6,000 mm (236.2 in) of X travel the Hartford SW-623 is one of the two longest SW box-guideway double-column machining centers. Its table is 6,000 x 2,200 mm (236.2 x 86.6 in), Y travel is 2,300 mm (90.6 in) and the table load is 16,000 kg (35,273 lb).
Six metres is the length at which Hartford's thermal statement stops applying. The maker says machine thermal displacement can be held within 0.03mm on double-column machines below 6 meters. The SW-623 sits at that boundary, so a buyer with tight tolerances over the full length should ask what figure applies to this model and under what shop conditions.
Mechanically it follows the SW pattern. Three box guideways on each column, a slant crossbeam, a square-guide Z ram with 780 mm of travel (1,070 mm optional) and a supported X axis ballscrew. The table has 24 T-slots across its width, entered as 28 x 250 (24) mm.
The #50 spindle is a gear type at 4,000 / 6,000 rpm or a DDS type at 10,000 / 12,000 rpm, with 15/18.5 kW as the base motor and 18.5/22 kW, 22/26 kW and 30/37 kW as options. Tool changers: S type, listed as S: 20, or arm type with 32 tools, or 40.

Frequently Asked Questions
01
X travel is 6,000 mm (236.2 in) and the table is 6,000 x 2,200 mm (236.2 x 86.6 in). Y travel is 2,300 mm (90.6 in) and Z travel 780 mm, or 1,070 mm as the option.
02
16,000 kg (35,273 lb) average load. The T-slot row reads 28 x 250 (24) mm. On a moving table this weight rides on the X guideways, so it also loads the X drive during acceleration.
03
The statement on the page reads that for double column machines below 6 meters, machine thermal displacement can reach within 0.03mm. The SW-623 has 6,000 mm of X travel, so whether the figure applies should be confirmed with Hartford.
04
The SW-626, with the same X travel, a 6,000 x 2,500 mm (236.2 x 98.4 in) table, 2,600 mm (102.4 in) of Y travel and a 16,500 kg (36,376 lb) load.
