Price estimate
We do not have a price for the Republic Lagun UTC-2280 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
Planning the floor comes first with the Republic Lagun UTC-2280. This Universal Turning Center has 73.62 in (1,870 mm) between centers, packs to 165.4 in x 90.6 in x 87.8 in (4,200 mm x 2,300 mm x 2,230 mm) and weighs 4,800 kg (10,582 lb) net, 5,400 kg (11,905 lb) gross.
For that footprint the buyer gets a working length of 66.14 in (1,680 mm) at up to Ø 12.8 in (325 mm) in diameter, under a Ø 22 in (550 mm) swing. Z travel is 70.1 in (1,780 mm) and X travel 11.8 in (300 mm). Rapid traverse in Z is 394 ipm (10 m/min), so the carriage needs several seconds to run the length of the bed; cycle planning for long parts should allow for it.
Holding accuracy over a long Z stroke is the harder problem. The maker's answer is a precision-ground 2 in (50 mm) diameter Z axis ball screw and a Meehanite frame with heavy ribbing, and it states positioning accuracy of ±0.0005 in (0.01 mm) over full X and Z travel, laser verified before shipping. Table repeatability is ± 0.0002 in (0.005 mm). The headstock is enclosed and ribbed to shed heat, which the maker links to avoiding thermal distortion on long turning jobs.
The spindle runs 35-3,500 rpm on an AC 12 HP (9 kW) Fanuc AC motor through an ASA A2-8 nose. Fluids are sized to match the bed: a 47.5 gal (180 liters) coolant tank, and a hydraulic tank of 6.6 gal (25 liters) as standard or 10.5 gal (40 liters) as an option. A manual 4-way tool post is standard.

Frequently Asked Questions
01
The packing size is 165.4 in x 90.6 in x 87.8 in (4,200 mm x 2,300 mm x 2,230 mm), length by width by height. Net weight is 4,800 kg (10,582 lb) and gross weight 5,400 kg (11,905 lb). The maker gives packing dimensions only, so ask for an installation drawing with door and tailstock clearances.
02
Positioning accuracy of ± 0.0005 in (0.01 mm), repeatability of ± 0.0002 in (0.005 mm) and resolution of ± 0.0001 in (0.002 mm). The maker says each UTC is laser verified for the positioning figure before shipment.
03
Maximum working length is 66.14 in (1,680 mm) and maximum working diameter Ø 12.8 in (325 mm). Swing over the bed is Ø 22 in (550 mm), and distance between centers is 73.62 in (1,870 mm).
04
Mainly in length. The UTC-22120 has 113 in (2,870 mm) between centers and 109.4 in (2,780 mm) of Z travel, and its Z ball screw is Ø 2.48 in (63 mm) instead of the Ø 1.97 in (50 mm) on the UTC-2280. Net weight is 5,300 kg (11,684 lb) for the UTC-22120.
