How much does the Accuway UT-400LX4 cost?
Price estimate
We do not have a price for the Accuway UT-400LX4 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
Four metres is where the Accuway UT-400LX4 works. Z travel is 4,100 mm (161.4 in), maximum turning length 3,980 mm (156.7 in), and the machine is 9 m long and weighs 19,000 kg (41,887 lb).
On a bed like this the rapid traverse rate tells the story of the mechanics. Z rapids at 6 m/min (236 in/min). The shorter beds of the same series are quicker in steps, 10 m/min (394 in/min) on the UT-400LX3 and 15 m/min (591 in/min) on the UT-400LX2, as the screw gets shorter. A turret return across the full travel is slow here, so programs for this machine should keep the tool near the work.
Nothing else is reduced. Turning diameter is 700 mm (27.6 in), X travel 380 mm (15.0 in), and the spindle has 30/37 kW (40.2/49.6 hp) with a 2-step gearbox. The spindle hole diameter is 131 mm (5.2 in) in the A2-11 column and 205 mm (8.1 in), 235 mm (9.3 in) or 258 mm (10.2 in) in the A2-15 columns.
The tailstock body travels 3,950 mm (155.5 in). Its quill is 160 mm (6.3 in) across with 150 mm (5.9 in) of travel. Four-metre parts will need intermediate support, and the steady rest is on the optional accessories list, so count it into the specification from the start. A linear scale and an auto door are also options. Standard tooling is a 12-station BOT turret.

Frequently Asked Questions
01
Maximum turning length is 3,980 mm (156.7 in) and Z-axis travel 4,100 mm (161.4 in). Maximum turning diameter is 700 mm (27.6 in), under a 900 mm (35.4 in) swing over bed and a 745 mm (29.3 in) swing over saddle.
02
The table gives 6 m/min (236 in/min) without comment. Long ball screws are speed-limited, which is consistent with the pattern in the series: the UT-400L, with 1,500 mm (59.1 in) of Z travel, rapids at 24 m/min (945 in/min).
03
Net weight is 19,000 kg (41,887 lb). Machine dimensions are 9 x 2.8 x 2.7 m (354.3 x 110.2 x 106.3 in) as length, width and height.
04
FANUC 0i-T controller, RJ-45 interface, rigid tapping, heat exchanger for the electric cabinet, 10.4" Colored LCD monitor, lubrication system, 4-bar coolant system, three-color warning light and gear box. Larger A2-15 spindle headstocks are listed as options.
