How much does the Hartford SW-435 cost?
Price estimate
We do not have a price for the Hartford SW-435 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 SW-435 has the widest gantry of the SW box-guideway double-column machining centers. Y travel is 3,500 mm (137.8 in) over a 4,000 x 3,000 mm (157.5 x 118.1 in) table, with 4,000 mm (157.5 in) of X travel and a table load of 16,000 kg (35,273 lb).
Its table rows differ from the neighbouring models in ways that show a heavier build. The base rides on 4 box guideways, where a narrower table needs fewer, and both the X and Y ballscrews are supported. The gear spindle is listed as a single 6,000 rpm version. The motor row is a single pair too, 18.5 / 22 kW (Cont. / 30 min), with no options printed.
A DDS spindle at 10,000 / 12,000 rpm is listed as the alternative to the gear head. Z travel is 780 mm, or 1,070 mm as the option.
Three metres between the columns admits parts that otherwise go to a gantry machine with a floor plate: large welded frames, turbine housings split on the centreline, wide press bolsters. The table still moves under the bridge, so the part's weight is on the X ways, and the 16,000 kg limit is the figure to check first. Tool changers are an S type, listed as S: 20, or an arm type with 32 tools, or 40.
