How much does the Huron DX 250-500 cost?
Price estimate
We do not have a price for the Huron DX 250-500 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 DX 250-500 is a short-bed chucking lathe with a large diameter capacity for its size. It turns up to 490 mm (19.3 in) across and 500 mm long, with 250 mm of X travel, on a machine weighing 4,000 kg (8,818 lb).
It opens the DX 250/350 series, which Huron builds on a monoblock bed with a 45° slant structure and roller-type linear guideways. Steeper bed angle and roller guides are the upgrades over the DX 200 family, aimed at heavier cuts and hard-part turning. Within the series this model is the lightest by a wide margin and the only one with a 500 mm swing.
The spindle is an A2-8 unit with a 90 mm bore, 75 mm of bar capacity and a 50-3,500 rpm range. Motor power is listed as 14.4/11 kW for Siemens and 15/11 kW for Fanuc. That is the fastest spindle in the DX 250/350 table, where the DX 250-700 stops at 2,500 rpm.
An 8-station bi-directional servo turret holds 25 x 25 mm tools and 40 mm boring bars, and Huron notes that a live-tool turret is available as an option for milling operations. The tailstock has an 85 mm quill and up to 500 kgf of thrust. Positioning is 0.007 mm and repeatability 0.005 mm. Footprint is 2,400 x 1,600 mm.
