How much does the Republic Lagun UTC-1740 cost?
Price estimate
We do not have a price for the Republic Lagun UTC-1740 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 UTC-1740 steps the Universal Turning Center range up to a 12 in (305 mm) wide bed. It is a 2 axis CNC lathe with a Ø 17.12 in (435 mm) swing, 37.40 in (950 mm) between centers and manual handwheels kept alongside the control.
Its numbers are those of a steady machine, not a fast one. The main motor is an AC 7.5 HP (5.5 kW) unit, the smallest motor rating in the UTC table, and the spindle tops out at 2,800 rpm: 30-450 rpm in the low range and 451-2,800 rpm in the high, changed pneumatically in 2 steps. Rapid traverse is 196.8 ipm (5 m/min) in X and 295.3 ipm (7.5 m/min) in Z. For comparison the UTC-1440 lists 295 ipm (7.5 m/min) and 394 ipm (10 m/min).
Against that, the slides are generous for the size. X travel is 9.05 in (230 mm), Z travel 35.43 in (900 mm), and the Z ball screw is Ø 1.57 in (40 mm) where the X screw is Ø 0.787 in (20 mm). Servo motors are 0.85 kW 5.39 N.m on X and 1.3 kW 8.34 N.m on Z. Working capacity with the manual 4 way tool post is 31.50 in (800 mm) long and 9.0 in (230 mm) in diameter; the hydraulic P8 turret brings that to 25.59 in (650 mm) and 8.66 in (220 mm).
The spindle nose is D1-6 with A1-6 optional, and the bore is Ø 2.06 in (52.5 mm). The tailstock quill is Ø 2.67 in (68 mm) with 6 in (153 mm) of travel and an MT No. 4 taper. Net weight is 4,739 lb (2,150 kg).

Strengths & Limitations
Strengths
- 12 in (305 mm) bed width under a Ø 17.12 in (435 mm) swing
- Ø 1.57 in (40 mm) Z-axis ball screw driven by a 1.3 kW 8.34 N.m servo motor
- 9.05 in (230 mm) of X travel and a 9.0 in (230 mm) maximum working diameter with the tool post
- Tailstock quill of Ø 2.67 in (68 mm) with 6 in (153 mm) of travel
- Handwheel operation retained next to a conversational control, per the maker's description
Limitations
- AC 7.5 HP (5.5 kW) main motor limits heavy roughing in steel
- Top speed of 2,800 rpm restricts surface speed on small diameters
- Rapids are only 196.8 ipm (5 m/min) in X and 295.3 ipm (7.5 m/min) in Z
- The hydraulic P8 turret is optional and cuts working length to 25.59 in (650 mm)

Frequently Asked Questions
01
X travel is 9.05 in (230 mm) and Z travel 35.43 in (900 mm). With the manual 4 way tool post the maximum working length is 31.50 in (800 mm) and the working diameter 9.0 in (230 mm). With the hydraulic P8 turret these are 25.59 in (650 mm) and 8.66 in (220 mm). Swing over the bed is Ø 17.12 in (435 mm).
02
The table lists an AC 7.5 HP (5.5 kW) main spindle motor. Speeds are infinitely variable within two ranges, 30-450 rpm and 451-2,800 rpm, with a pneumatic change between the 2 steps. The maker's feature list says constant surface speed is standard.
03
Bed length. The UTC-1760 has 57.08 in (1,450 mm) between centers and 55.11 in (1,400 mm) of Z travel, against 37.40 in (950 mm) and 35.43 in (900 mm) on the UTC-1740. Swing, bed width, motor and speed ranges are the same in the maker's table.
04
A D1-6 camlock nose with a No. 6 MT internal taper is listed, with A1-6 as an option. The spindle bore is Ø 2.06 in (52.5 mm), and a Ø 2 in (51 mm) bore is listed as optional. The feature list quotes a 2 in bar capacity for the cam-lock D1-6 spindle.
