How much does the Republic Lagun UTC-1440 cost?
Price estimate
We do not have a price for the Republic Lagun UTC-1440 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-1440 is the smallest column in the maker's Universal Turning Center table: a two-axis CNC lathe that keeps its handwheels, with 14.17 in (360 mm) of swing over the bed and 35 in (880 mm) between centers. Lagun Engineering describes it as having constant surface speed, a conversational control system and manual hand wheel control, so it can be run like an engine lathe for a one-off and under program for a batch.
Capacity depends on what holds the tools. With the standard manual 4 way tool post the table gives a maximum working length of 29.52 in (750 mm) and a working diameter of 6.7 in (170 mm). Fit the optional hydraulic P8 turret and those fall to 24.8 in (630 mm) and 6.29 in (160 mm). An electric H4 turret is the other listed option. Travels are 8.07 in (205 mm) in X and 32.08 in (815 mm) in Z.
The headstock is geared, with two infinitely variable ranges selected by a pneumatic auto-shift: 25-480 rpm in low and 481-3,000 rpm in high. The main motor is rated 10 HP (7.5 kW), or 15 HP (11 kW) on the 30 min rating. The spindle bore is 2.066 in (52.5 mm) behind a Camlock D1-6 nose, with ASA A1-6 as the option.
The bed is 10.236 in (260 mm) wide with three V ways and three flats, induction hardened and ground, and the maker says the base is a one-piece Meehanite casting whose chip pan pulls out from the front so the machine can stand against a wall. Rapids are 295 ipm (7.5 m/min) in X and 394 ipm (10 m/min) in Z, and positioning accuracy and repeatability are both listed at ±0.0002 in (±0.005 mm). Net weight is 4,629 lb (2,100 kg).

Strengths & Limitations
Strengths
- Runs by handwheel or by program: the maker lists manual hand wheel control alongside a conversational control system and constant surface speed
- Two infinitely variable geared ranges, 25-480 rpm and 481-3,000 rpm, changed by a pneumatic auto-shift
- 2.066 in (52.5 mm) spindle bore on a 14.17 in (360 mm) swing machine
- Positioning accuracy and repeatability both listed at ±0.0002 in (±0.005 mm)
- Front-removal chip pan lets the machine sit against a wall, according to the maker's feature list
Limitations
- The hydraulic P8 turret is an option and shortens the working length from 29.52 in (750 mm) to 24.8 in (630 mm)
- Maximum working diameter is 6.7 in (170 mm) with the tool post, well under the 14.17 in (360 mm) swing over the bed
- Rapids of 295 ipm (7.5 m/min) in X and 394 ipm (10 m/min) in Z are slow for production turning
- Turning tools are limited to a 0.78 in (20 mm) section

Frequently Asked Questions
01
Swing over the bed is 14.17 in (360 mm) and swing over the cross slide is 7.08 in (180 mm), with 35 in (880 mm) between centers. The maximum working diameter is 6.7 in (170 mm) with the 4 way tool post and 6.29 in (160 mm) with the hydraulic P8 turret. Working length is 29.52 in (750 mm) or 24.8 in (630 mm) in the same order.
02
A geared headstock with two infinitely variable ranges, 25-480 rpm and 481-3,000 rpm, shifted pneumatically. The main motor is 10 HP (7.5 kW) with a 30 min rating of 15 HP (11 kW). The nose is Camlock D1-6, with ASA A1-6 optional, and the bore is 2.066 in (52.5 mm).
03
No. The standard tool station is a manual 4 way tool post. An electric H4 turret or a hydraulic P8 turret is optional, and the P8 reduces the working length to 24.8 in (630 mm). The maker also notes that provision can be made for controls for options such as a hydraulic tailstock quill and automatic turret index.
04
The UTC-1640 has the same 35 in (880 mm) between centers and the same 32.08 in (815 mm) of Z travel, but its swing over the bed is 16.14 in (410 mm) against 14.17 in (360 mm) here. Bed width, spindle bore and speed ranges are the same in the maker's table, so the choice comes down to part diameter.
