How much does the Hartford SW-423 cost?
Price estimate
We do not have a price for the Hartford SW-423 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-423 is a four-metre box-guideway double-column machining center: 4,000 mm (157.5 in) of X travel, 2,300 mm (90.6 in) of Y and a 4,000 x 2,200 mm (157.5 x 86.6 in) table rated for 12,000 kg (26,455 lb).
This model's page is the one on which Hartford headlines an automatic tool-type angular head changing system. An angle head turns the vertical spindle into a horizontal one, so the sides of a large part can be milled, drilled and tapped without turning the part over. When the head is changed automatically, like a tool, side machining becomes part of the program instead of a manual intervention.
The spindle is #50. The gear head runs 4,000 / 6,000 rpm and the DDS spindle 10,000 / 12,000 rpm. Motor ratings are 15/18.5 kW, with 18.5/22 kW, 22/26 kW and 30/37 kW as options (Cont. / 30 min).
Tools are stored in an S-type magazine, listed as S: 20, or an arm-type magazine with 32 tools, or 40. Z travel is 780 mm, optionally 1,070 mm. Sixteen T-slots cross the table, listed as 28 x 250 (16) mm.
