How much does the Accuway UT-400LX3 cost?
Price estimate
We do not have a price for the Accuway UT-400LX3 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
Three metres of heavy turning: the Accuway UT-400LX3 has a Z travel of 3,100 mm (122.0 in) and turns 2,980 mm (117.3 in) between the chuck and the tailstock at up to 700 mm (27.6 in) in diameter.
How does it differ from the three-metre machines in Accuway's lighter series? The UT-380LX3 has an 18.5/22 kW (24.8/29.5 hp) motor and a largest bore of 166.5 mm (6.6 in). The UT-400LX3 has 30/37 kW (40.2/49.6 hp) and bores up to 258 mm (10.2 in), with a tailstock quill of 160 mm (6.3 in). Turning diameters are close, so the choice between them is about bore, power and the weight of the workpiece, not about swing.
The UT-400LX3 is 7.9 x 2.8 x 2.7 m (311.0 x 110.2 x 106.3 in) and is listed at 17,000 kg (37,478 lb). Z rapid traverse is 10 m/min (394 in/min); X travels 380 mm (15.0 in) at 20 m/min (787 in/min).
Speeds are low by design. The quickest column, A2-11 with a 15 in chuck, reaches 2,000 rpm. The three A2-15 columns run 1,500 rpm, 850 rpm and 800 rpm, the last with a 24 in chuck. At these diameters surface speed is reached early, and the 2-step gearbox, a standard accessory, is there for torque. A steady rest is optional and, on a part this long, usually needed.
