How much does the Republic Lagun UTC-1640 cost?
Price estimate
We do not have a price for the Republic Lagun UTC-1640 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
A 16.14 in (410 mm) swing on the short bed: that is the UTC-1640 in Republic Lagun's Universal Turning Center range. It shares its 35 in (880 mm) center distance with the UTC-1440 and its swing with the UTC-1660, and the maker gives it a column in the series table instead of a product page of its own.
What the extra swing buys is working diameter. The table lists a maximum of 8.66 in (220 mm) with the standard 4 way tool post and 8.27 in (210 mm) with the optional hydraulic P8 turret, on 8.5 in (216 mm) of X travel. Length is unchanged from the smaller machine: 29.52 in (750 mm) with the tool post, 24.8 in (630 mm) with the turret, and 32.08 in (815 mm) of Z travel. Swing over the cross slide is 9.05 in (230 mm).
Both axes run on ground ball screws, 0.787 in (20 mm) in X and 1.260 in (32 mm) in Z, driven by servo motors of 1 HP (0.75 kW, 3.5 Nm) and 1.61 HP (1.2 kW, 7 Nm). The spindle runs from 25 to 3,000 rpm in two pneumatically shifted ranges through a 2.066 in (52.5 mm) bore with a No. 6 MT taper. The maker's table does not give a consistent main motor rating or spindle nose for this column, so confirm both before ordering.
Construction follows the other small UTC machines: a bed 10.236 in (260 mm) wide with three V ways and three flats, a tailstock quill of 2.283 in (58 mm) with 5.5 in (140 mm) of travel, and a net weight of 4,739 lb (2,150 kg).

Strengths & Limitations
Strengths
- 8.66 in (220 mm) maximum working diameter with the 4 way tool post, on a machine only 35 in (880 mm) between centers
- Ground ball screws of 0.787 in (20 mm) in X and 1.260 in (32 mm) in Z
- Positioning accuracy and repeatability listed at ±0.0002 in (±0.005 mm), with ±0.0001 in (±0.00254 mm) resolution
- Constant surface speed is standard, per the series feature list
Limitations
- No consistent main motor rating or spindle nose is published for this column of the series table
- Working length is 29.52 in (750 mm), dropping to 24.8 in (630 mm) with the hydraulic P8 turret
- A hydraulic pump of 1 HP (0.75 kW) is listed only as an option, so hydraulic functions are extras

Frequently Asked Questions
01
Swing over the bed is 16.14 in (410 mm) and over the cross slide 9.05 in (230 mm). Maximum working diameter is 8.66 in (220 mm) with the manual 4 way tool post or 8.27 in (210 mm) with the hydraulic P8 turret. Working length is 29.52 in (750 mm) and 24.8 in (630 mm) respectively, with 35 in (880 mm) between centers.
02
The UTC-1660 is the long-bed version of the same swing: 55 in (1,400 mm) between centers and 52.16 in (1,325 mm) of Z travel, against 35 in (880 mm) and 32.08 in (815 mm) on the UTC-1640. Net weight rises from 4,739 lb (2,150 kg) to 4,960 lb (2,250 kg) on the UTC-1660.
03
X is driven by a 1 HP (0.75 kW, 3.5 Nm) servo motor through a 0.787 in (20 mm) ball screw, Z by a 1.61 HP (1.2 kW, 7 Nm) motor through a 1.260 in (32 mm) screw. Rapid traverse is 295 ipm (7.5 m/min) in X and 394 ipm (10 m/min) in Z.
04
25-3,000 rpm in two infinitely variable ranges with a pneumatic auto-shift: 25-480 rpm in low gear and 481-3,000 rpm in high. The spindle bore is 2.066 in (52.5 mm) and the internal taper is No. 6 MT. The series feature list states that constant surface speed is standard.
