How much does the Johnford VTC-3000ATC cost?
Price estimate
We do not have a price for the Johnford VTC-3000ATC 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
Four metres of swing on a single-motor table drive: the Johnford VTC-3000ATC turns Ø4,000 mm (Ø157.5 in) over a Ø3,000 mm (Ø118.1 in) table. It is the largest VTC before the twin-motor machines begin.
Several rows of the maker's table change at this size, and they show how the machine is configured. The motor is given as 60 / 75 kW (80.5 / 100.6 hp) with no smaller standard version. Table speed drops to 2-75 rpm, and torque is 47,275 Nm (34,870 lb-ft). The tool magazine is listed as 12 tools standard with no optional sizes. Coolant is specified as two pumps, a 1.3kW chip flushing pump at 3 bar and a 3.0kW pump for coolant through the tool tip at 5 bar, where the VTC-2500ATC lists one 0.98 kW pump.
Seventy-five rpm at the table is slow in absolute terms and right for the diameter. At a four-metre swing the rim is moving quickly even at low rpm, so carbide grades run in their range on the outside diameter; it is on bores and faces near the centre that surface speed falls short.
Load capacity does not rise with the table. It stays at 15,000 kg (33,000 lb), as on the VTC-2500ATC. That makes this a machine for large light parts: rings, shells, fabricated housings, antenna and bearing mounts. For heavy solids of this diameter, the VTC-4000ATC carries 60,000 kg (132,000 lb).
Travels are 2,435 mm (95.87 in) in X, 1,000 mm (39.4 in) in Z and 1,000 mm (39.4 in) in W. Weight is 85,000 kg (187,000 lb).
