Price estimate
We do not have a price for the You Ji VTL4500ATC 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 largest machine in You Ji's VTL table is the VTL4500ATC, a CNC vertical turning lathe with a Ø4,500 mm (177.2 in) table. It turns Ø4,800 mm (189.0 in) and swings Ø5,100 mm (200.8 in).
Mechanically it is the VTL4000ATC with a wider envelope. The spindle motor is the same 100 kW (134.1 hp), the speed range the same 1-60 rpm, the loading weight the same 30,000 kg (66,138 lb) and the turning height the same 1,600 mm (63.0 in). The tool shank row again reads BT-50/BT-60.
The building is where the two part ways. This model needs 13,000 x 10,500 mm (511.8 x 413.4 in) of floor, two metres deeper than the VTL4000ATC, and stands 7,800 mm (307.1 in) high, the tallest figure in the VTL table. Raised-column builds, which the model key lists for the series, go higher still.
Since load does not increase, the VTL4500ATC is the machine for parts that are wide but not dense: fabricated rings, large-diameter flanges, tunnel-boring and crane slewing components, antenna and generator frames. When weight is the problem, the VTH4500ATC lists the same table, swing and turning diameter with 60,000 kg (132,275 lb) on a hydrostatic table bearing. A double ram build lets two tools work on a face this wide at the same time, which shortens long facing passes considerably.

Frequently Asked Questions
01
Ø4,800 mm (189.0 in) in turning diameter within a Ø5,100 mm (200.8 in) swing, up to 1,600 mm (63.0 in) high and 30,000 kg (66,138 lb). The table is Ø4,500 mm (177.2 in).
02
Only in size. The VTL4000ATC turns Ø4,300 mm (169.3 in) on 12,500 x 8,500 mm (492.1 x 334.6 in) of floor at 7,400 mm (291.3 in) height. The VTL4500ATC turns Ø4,800 mm (189.0 in) on 13,000 x 10,500 mm (511.8 x 413.4 in) at 7,800 mm (307.1 in). Motor, speed, load and turning height are the same.
03
Yes. The VTH4500ATC has the same Ø4,500 mm (177.2 in) table and Ø4,800 mm (189.0 in) turning diameter with a hydrostatic table bearing, a 60,000 kg (132,275 lb) loading weight and a 100/140 kW (134.1/187.7 hp) motor.
04
A 100 kW (134.1 hp) spindle motor driving the table at 1-60 rpm. The catalogue does not list table torque or the number of gear ranges.
