How much does the Republic Lagun AT-1860-G-TW-CNC cost?
Price estimate
We do not have a price for the Republic Lagun AT-1860-G-TW-CNC 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 longest of Republic Lagun's American Turnmaster CNC lathes, the AT-1860-G-TW-CNC has 57.08 in (1,450 mm) between centers under an 18.11 in (460 mm) swing. The maker presents it on one page with the shorter AT-1840-G-TW-CNC as a fully automated lathe with a two-range gear head.
Usable stroke is 53.15 in (1,350 mm) in Z with the 4 way tool post. Mounting the hydraulic P8 turret in the rear position brings it to 47.64 in (1,210 mm). The spindle runs 27-870 rpm in the low range and 871-2,500 rpm in the high, through a standard bore of Ø 2.36 in (60 mm) or an optional Ø 2.56 in (65 mm). The motor entry for this column does not agree with itself in the maker's table, so the rating is one to confirm; the AT-1840-G-TW-CNC is listed at 10 HP (7.5 kW) continuous.
What ships with the machine is spelled out: a rotating center MT.4, level pads, a tool set and box, a machine light, and the operation manual and parts list. The tailstock is manual, with a Ø 2.677 in (68 mm) quill and 6 in (153 mm) of travel, and the coolant pump is 1/4 HP (0.188 kW). A hydraulic oil pump of 1 HP (0.75 kW) or 2 HP (1.5 kW) appears only as an option, which matters if the turret or powered workholding is wanted.
On the floor this is a substantial lathe: 5,732 lb (2,600 kg) net and 6,834 lb (3,100 kg) gross on a bed 12 in (305 mm) wide. Rapid traverse is 394 ipm (10 m/min) in Z and 295 ipm (7.5 m/min) in X.
