How much does the Accuway UT-400LX3Y cost?
Price estimate
We do not have a price for the Accuway UT-400LX3Y 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
Milling on a three-metre heavy lathe is the purpose of the Accuway UT-400LX3Y. It has a Y axis of ±75 mm (±3.0 in), a BMT-85 turret with rotary tools at 4,000 rpm, and a rotary tool motor of 7.5/11 kW (10.1/14.8 hp).
Those figures change what can be done on the part. With that power at the tool and Y stroke on both sides of centre, keyways in large shafts, flats on roll journals and bolt patterns on big flanges are milling jobs of normal size, not light finishing passes. The BMT-85 interface is correspondingly large.
Z travel is 3,100 mm (122.0 in) and turning length 2,900 mm (114.2 in), a little less than the two-axis UT-400LX3 at 2,980 mm (117.3 in). Turning diameter is 700 mm (27.6 in). The Y-axis structure raises the swing over bed to 1,200 mm (47.2 in) and the swing over saddle to 1,040 mm (40.9 in), and the machine to 3.0 m in height and 19,000 kg (41,887 lb). Z rapid traverse is 6 m/min (236 in/min), slower than the UT-400LX3's 10 m/min (394 in/min).
The spindle row repeats the UT-400 choices: 30/37 kW (40.2/49.6 hp) with a 2-step gearbox, noses A2-11 and A2-15, bores from 131 mm (5.2 in) to 258 mm (10.2 in). Chuck sizes are printed only for the first two columns, 15 in and 20 in. Accuway's page for this model carries no accessory lists, so standard and optional equipment have to come from the quotation.
