Price estimate
We do not have a price for the You Ji VTH8000ATC 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
You Ji's biggest vertical turning lathe is the VTH8000ATC. The hydrostatic table measures Ø8,000 mm (315.0 in), the maximum turning diameter is Ø8,900 mm (350.4 in) and the maximum loading weight is 300,000 kg (661,376 lb).
Every figure in its column is the largest of its kind in the maker's vertical lathe tables, or equal to the largest. Swing is Ø9,400 mm (370.1 in). Turning height is 2,600 mm (102.4 in). The spindle motor row reads 2 x 100/140 kW (2 x 134.1/187.7 hp), and the table turns at 3-20 rpm.
At the rim of a nine-metre part, 20 rpm is already a high cutting speed, so the narrow range is no handicap for turning. It does shape the tooling plan. Drilling and milling on the ATC+C build rely on the ram spindle, not on table speed, and the catalogue gives no figures for that spindle. Anyone specifying bolt-circle drilling or keyway milling on such a part should ask for them.
The machine stands on 21,000 x 15,000 mm (826.8 x 590.6 in) and is 10,400 mm (409.4 in) high in the standard column height; three raised-column steps and a double ram are listed. Tool shank is BT-50/BT-60. Work for a machine like this is ordered by the piece: large hydro runners, nuclear and petrochemical vessel rings, and the biggest slewing bearings.
