You Ji VTH4000ATC

Q: How much does the You Ji VTH4000ATC cost?

The price estimate for the You Ji VTH4000ATC is uncertain: we have no price for it that we can cite and no estimate we can stand behind, so we give no figure. Configuration, tooling, automation and installation move the final price substantially. A specific price can be requested at https://machinetoolindex.com/machines/you-ji-vth4000atc#price; the request is passed to You Ji or an authorised dealer.

Price estimate

Uncertain

We do not have a price for the You Ji VTH4000ATC 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

Sixty tonnes on a four-metre table: the You Ji VTH4000ATC is rated for a 60,000 kg (132,275 lb) loading weight and driven by a 100/140 kW (134.1/187.7 hp) spindle motor. It is a CNC vertical turning lathe with a hydrostatic table bearing, Ø4,000 mm (157.5 in) across.

Both of those ratings are a step up within the VTH series. The VTH3500ATC stops at 45,000 kg (99,206 lb) and 60/84 kW (80.5/112.6 hp). Table speed stays at 1-75 rpm, so the extra power goes into torque at the same speeds.

The envelope is Ø4,300 mm (169.3 in) of turning diameter, Ø4,600 mm (181.1 in) of swing and 1,600 mm (63.0 in) of turning height. For taller parts the key lists three column height increases. The floor dimension is 14,500 x 9,600 mm (570.9 x 378.0 in) and the height 7,400 mm (291.3 in).

You Ji has three machines on a Ø4,000 mm table, and their load ratings tell them apart. The VTL4000ATC and the VTS4000ATC are each rated 30,000 kg (66,138 lb); the VTH4000ATC doubles that. A steam-turbine casing half, a large ball-mill end cap or a nuclear-grade flange forging can exceed the rating of those two machines well before it fills the swing, and that is the case for this model. Tool shank is BT-50/BT-60, with ATC, ATC+C and double ram builds.

Frequently Asked Questions

01 How much weight can the VTH4000ATC table take?

60,000 kg (132,275 lb). The VTL4000ATC and VTS4000ATC, which have the same table diameter, are rated 30,000 kg (66,138 lb) each.

02 What motor drives the table?

The spindle motor is listed as 100/140 kW (134.1/187.7 hp) and the speed range as 1-75 rpm. The VTH3500ATC below it has 60/84 kW (80.5/112.6 hp) with the same speed range.

03 What are the turning dimensions?

Maximum turning diameter Ø4,300 mm (169.3 in), maximum swing Ø4,600 mm (181.1 in) and maximum turning height 1,600 mm (63.0 in) on a Ø4,000 mm (157.5 in) table.

04 Can it be built with two rams or a C-axis?

Yes to both, according to the VTH model key: 2R is the double ram build and ATC+C is the automatic tool changer with C-axis function. The key also lists three column height increases. The tool shank is BT-50/BT-60.
