How much does the Republic Lagun UTC-1760 cost?
Price estimate
We do not have a price for the Republic Lagun UTC-1760 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 lists the UTC-1760 as the long-bed partner of the UTC-1740: the same Ø 17.12 in (435 mm) swing and 12 in (305 mm) bed, stretched to 57.08 in (1,450 mm) between centers. It appears as a column in the maker's Universal Turning Center table and has no separate product page.
The added length shows up directly in the work it will take. Maximum working length is 51.18 in (1,300 mm) with the manual 4 way tool post and 45.27 in (1,150 mm) with the optional hydraulic P8 turret, on 55.11 in (1,400 mm) of Z travel. Working diameter stays at 9.0 in (230 mm) and 8.66 in (220 mm) for the same two tool stations, and X travel is 9.05 in (230 mm).
One detail differs at the tailstock. The table gives this model an MT No. 5 quill taper, while the UTC-1740 column reads MT No. 4; quill diameter and travel are Ø 2.67 in (68 mm) and 6 in (153 mm) on both. Anyone ordering centers or tailstock tooling should check which taper the machine actually ships with.
Drive figures are modest for a bed this long. An AC 7.5 HP (5.5 kW) motor turns the spindle through 30-450 rpm and 451-2,800 rpm ranges, and Z rapid traverse is 295.3 ipm (7.5 m/min), so a full-length return stroke takes noticeable time. The Z axis runs on a Ø 1.57 in (40 mm) ball screw with a 1.3 kW 8.34 N.m servo motor. Net weight is 5,291 lb (2,400 kg), gross 6,393 lb (2,900 kg), and the packing length is 124.4 in (3,160 mm).

Strengths & Limitations
Strengths
- 51.18 in (1,300 mm) working length with the 4 way tool post
- 55.11 in (1,400 mm) of Z travel on a Ø 1.57 in (40 mm) ball screw
- MT No. 5 tailstock quill taper listed for this length
- Three-V-way bed that the maker says keeps the carriage aligned and prevents twisting
Limitations
- Only AC 7.5 HP (5.5 kW) at the spindle for a machine with 57.08 in (1,450 mm) between centers
- Z rapid traverse of 295.3 ipm (7.5 m/min) makes long return moves slow
- Working diameter is limited to 9.0 in (230 mm) even though the swing is Ø 17.12 in (435 mm)
- Packs to 124.4 in (3,160 mm) long and weighs 5,291 lb (2,400 kg) net

Frequently Asked Questions
01
Distance between centers is 57.08 in (1,450 mm) and Z travel is 55.11 in (1,400 mm). The maximum working length is 51.18 in (1,300 mm) with the manual 4 way tool post, or 45.27 in (1,150 mm) when the hydraulic P8 turret is fitted.
02
The maker's table lists MT No. 5 for the quill taper on this model, with a Ø 2.67 in (68 mm) quill and 6 in (153 mm) of quill travel. The shorter UTC-1740 is listed with MT No. 4, so confirm the taper before buying centers.
03
Net weight is 5,291 lb (2,400 kg) and gross weight 6,393 lb (2,900 kg). The packing size is given as 124.4 in (3,160 mm) x 79.33 in x 88.2 in (2,015 mm x 2,240 mm), length by width by height.
04
The table lists an A1-6 spindle nose in place of the D1-6, a Ø 2 in (51 mm) spindle bore in place of Ø 2.06 in (52.5 mm), the hydraulic P8 turret, and a hydraulic oil pump of 1 HP (0.75 kW) or 2 HP (1.5 kW). The series feature list adds that provision can be made for hydraulic tailstock quill and automatic turret index controls.
