Huron KXG 45-23

Q: How much does the Huron KXG 45-23 cost?

The price estimate for the Huron KXG 45-23 is uncertain: we have no price for it that we can cite and no estimate we can stand behind, so we give no figure. Configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/huron-kxg-45-23#price; the request is passed to Huron or an authorised dealer.

We do not have a price for the Huron KXG 45-23 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 Huron KXG 45-23 is the mid-size gantry of the KXG range and the first with the wide 2,300 mm Y axis. Travels are 4,500 x 2,300 x 800 mm (177.2 x 90.6 x 31.5 in). The fixed table is 4,700 x 2,480 mm and carries 21,000 kg (46,297 lb).

That table is wider than the Y stroke, so the full width is there for clamping while the head covers 2,300 mm of it. Panels, skins and large mould halves that would not sit on the 1,390 mm table of the KXG 45-14 fit here with room for fixturing.

The crossrail is Huron's reinforced U-type, with the moving axes optimized by finite element calculation. Despite the wider span the rapids hold at 60 m/min on X and Y and 45 m/min on Z, and the machine weighs 80,000 kg (176,368 lb).

For cutting, the KXG 45-23 uses the same package as its siblings: forked head with B at +/- 105° and C at +/- 200°, 100 rpm on both, and an HSK 63-A spindle of 75 kW, 75 Nm and 20,000 rpm. Positioning is given as 0.025 mm on X, 0.010 mm on Y and Z, and 10 sec on the head axes. Repeatability is 0.005 mm. The footprint is 9,053 x 10,007 mm.
