Price estimate
We do not have a price for the Republic Lagun AT-1440-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 Republic Lagun AT-1440-G-TW-CNC is the smallest of the American Turnmaster CNC lathes: a 2 axes machine with a Ø 14.17 in (360 mm) swing over the bed and 35.8 in (910 mm) between centers with the manual tailstock. The product page heads it RL-1440-G-TW-CNC, while the description and the specification table use the AT name.
Speed is its distinguishing figure. The table lists a 40-5,000 rpm spindle with an ASA A2-5 nose, which puts small-diameter work in brass, aluminium and plastics within reach of proper surface speeds. The standard main motor is rated 7.4 HP (5.5 kW) continuous and 10 HP (7.5 kW) on the 15 min rating; the optional motor is 10 HP (7.5 kW) continuous and 14.75 HP (11 kW) for 15 min. The standard spindle bore is Ø 2.3 in (58 mm), with Ø 1.8 in (45 mm) listed as the option.
Travels depend on the tool station. With the 4 way tool post X travel is 8.07 in (205 mm) and Z travel 32 in (815 mm). With the P8 turret in the rear position X becomes 10.7 in (272 mm) and Z 26.38 in (670 mm). Rapid traverse is 295 ipm (7.5 m/min) in X and 394 ipm (10 m/min) in Z.
Republic Lagun's text is not consistent about the control. The feature list names a FANUC 0i Mate – TC controller, and the description says the lathe comes with the FANUC CNC Series 0i-F Plus display with a 10.4 in screen. Buyers should have the control model written into the quotation. The machine weighs 4,630 lb (2,100 kg) net and ships in a case 105.51 in (2,680 mm) long.

Frequently Asked Questions
01
A FANUC control. The feature list on the maker's page reads FANUC 0i Mate – TC, and the description says the lathe is equipped with the FANUC CNC Series 0i-F Plus display with a 10.4 in screen. Since the two do not match, confirm the exact control with Lagun Engineering.
02
The table lists 40-5,000 rpm. The standard main motor is 7.4 HP (5.5 kW) continuous and 10 HP (7.5 kW) on the 15 min rating, and the optional motor is 10 HP (7.5 kW) continuous and 14.75 HP (11 kW) on the 15 min rating.
03
With the 4 way tool post, X travel is 8.07 in (205 mm) and Z travel is 32 in (815 mm). With the P8 turret mounted in the rear position, X travel is 10.7 in (272 mm) and Z travel 26.38 in (670 mm). Tailstock quill travel is 5.5 in (140 mm).
04
The AT-1640-G-TW-CNC has a larger swing, Ø 16.14 in (410 mm) against Ø 14.17 in (360 mm), and slightly more X travel with the tool post, 8.5 in (216 mm) against 8.07 in (205 mm). Distance between centers, bed width and the main motor ratings are the same in the maker's table.
