How much does the Johnford VTC-6000ATC cost?
Price estimate
We do not have a price for the Johnford VTC-6000ATC 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 Johnford's VTC table, the VTC-6000ATC swings Ø7,000 mm (Ø275.6 in) and carries 100,000 kg (220,000 lb) on a Ø6,000 mm (Ø236.2 in) table.
Every drive figure is at the top of the series. Standard power is 60 / 75 kW (80.5 / 100.6 hp) and the option is a 100 kW motor, in both cases with twin motors and twin pinions. Maximum torque is 267,507 Nm (197,313 lb-ft). Table speed is 1-30 rpm, half the range of the VTC-5000ATC, which fits a table carrying a hundred tonnes.
Parts for a machine like this are few and specific: hydro turbine runners and head covers, ship propulsion gear wheels, rolling mill housings, nuclear and petrochemical vessel flanges, the kiln tyres and girth gears of cement plants. They are usually one-off or small-batch, each worth more than most machine tools, and the turning is slow, heavy and long.
For such work the height options are as important as the diameter. Turning height is 2,500 mm (98.4 in) as standard and can be ordered at 3,000 mm (118.1 in), 3,500 mm (137.8 in) or 4,000 mm (157.5 in). The ram travels 1,500 mm (59.1 in) and the X axis 5,255 mm (206.9 in). Tools up to 80 kg (176 lb) are changed automatically in 30 sec from the 12-tool magazine.
The machine itself weighs 180,000 kg (396,000 lb) and measures 13,647 x 9,655 x 8,000 mm (537.3 x 380.1 x 315 in). Hall, crane and foundation are designed around it.
