How much does the Republic Lagun UTC-2260 cost?
Price estimate
We do not have a price for the Republic Lagun UTC-2260 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-2260 is built around its spindle. Lagun Engineering describes an extra-large 3.58 in (91 mm) spindle bore with an A2-8 spindle mount, on a Universal Turning Center with a Ø 22 in (550 mm) swing and 53.93 in (1,370 mm) between centers.
That bore lets sizeable bar and tube pass through the headstock, which suits the long-shaft and chucking mix the maker names as the machine's purpose. The spindle is carried in a single cylinder bearing housing with double row cylindrical roller bearings and angular contact thrust bearings, grease lubricated, and the description mentions a pressure pump in the base that lubricates the head with oil. Speed is infinitely variable over 35-3,500 rpm with constant surface speed, from an AC 12 HP (9 kW) wide range Fanuc AC spindle motor.
Turning capacity is Ø 12.8 in (325 mm) in diameter and 46.45 in (1,180 mm) in length. X travel is 11.8 in (300 mm) on a full-length slide that the maker says rides on Turcite surfaces, and Z travel is 50.4 in (1,280 mm) on a precision ground ball screw listed at Ø 1.97 in (50 mm). The tailstock has a Ø 3.35 in (85 mm) quill with #5 MT taper and 7 in (178 mm) of travel.
The bed casting sits on a cast iron pedestal and has two V and two flat ways, induction hardened and ground. Net weight is 4,400 kg (9,700 lb). Standard tooling is a manual 4-way tool post for 1 in (25 mm) tools, so a turret, if needed, has to be raised with the maker. Coolant capacity is 31.70 gal (120 liters).
