How much does the You Ji VTH3500ATC cost?
Price estimate
We do not have a price for the You Ji VTH3500ATC 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
Take the VTH3000ATC, widen the table to Ø3,500 mm (137.8 in), and the result is the You Ji VTH3500ATC. It is a hydrostatic-table vertical turning lathe that turns Ø3,800 mm (149.6 in) and swings Ø4,100 mm (161.4 in).
The heavy-duty ratings carry over unchanged from the smaller model: 45,000 kg (99,206 lb) of loading weight, a 60/84 kW (80.5/112.6 hp) spindle motor, 1-75 rpm and 1,700 mm (66.9 in) of turning height. What changes is the frame around them. The floor dimension becomes 14,500 x 9,600 mm (570.9 x 378.0 in), which is also the figure for the VTH4000ATC.
That shared footprint frames the buying decision. The VTH4000ATC sits on the same plot and brings a 100/140 kW (134.1/187.7 hp) motor and 60,000 kg (132,275 lb), so the VTH3500ATC makes sense when parts are certain to stay under Ø3,800 mm (149.6 in) and under 45 tonnes.
You Ji's key gives the series an automatic tool changer, an optional C-axis function, a double ram and three raised-column heights; the tool shank is BT-50/BT-60. Machine height is 7,400 mm (291.3 in). Hydro-turbine runners, gearbox housings for mills, and large forged rings before splitting are typical loads.
