How much does the Republic Lagun AT-1660-G-TW-CNC cost?
Price estimate
We do not have a price for the Republic Lagun AT-1660-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
Republic Lagun's AT-1660-G-TW-CNC stretches the American Turnmaster gear head CNC lathe to 55.9 in (1,420 mm) between centers while keeping a Ø 16.14 in (410 mm) swing. It is a 2 axes machine aimed at shaft work that a short bed cannot hold.
How much of that length is usable depends on the tool station. The table lists 52 in (1,325 mm) of Z travel with the 4 way tool post and 46.45 in (1,180 mm) with the hydraulic P8 turret in the rear position. Cross travel goes the other way: 8.5 in (216 mm) with the tool post, 10.7 in (272 mm) with the turret. The tailstock is manual, with 5.5 in (140 mm) of quill travel.
The control is described at more length than the iron. According to the maker the lathe comes with the FANUC CNC Series 0i-F Plus display, a 10.4 in screen, customizable functions for building machine-specific screens, and FANUC's Fine Surface Technology and Fast Cycle-time Technology. The feature list, however, reads FANUC 0i Mate – TC, so the exact control needs confirming. No clean spindle speed entry is printed for this column.
Power is the same as on the shorter models: 7.4 HP (5.5 kW) continuous and 10 HP (7.5 kW) for 15 min as standard, or 10 HP (7.5 kW) and 14.75 HP (11 kW) with the optional motor. For the longer bed the machine weighs 4,960 lb (2,250 kg) net and 5,842 lb (2,650 kg) gross, and the packing case measures 125.6 in (3,190 mm) x 79.92 in (2,030 mm) x 86.61 in (2,200 mm).

Frequently Asked Questions
01
Distance between centers with the manual tailstock is 55.9 in (1,420 mm). Z travel is 52 in (1,325 mm) with the 4 way tool post and 46.45 in (1,180 mm) with the hydraulic P8 turret in the rear position. The packing length is 125.6 in (3,190 mm).
02
The description names the FANUC CNC Series 0i-F Plus display with a 10.4 in screen and customizable functions, plus FANUC's Fine Surface Technology and Fast Cycle-time Technology. The feature list on the same page reads FANUC 0i Mate – TC, so ask which control is fitted.
03
