How much does the Johnford VTC-1600ATC cost?
Price estimate
We do not have a price for the Johnford VTC-1600ATC 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
Two metres of turning diameter is the headline of the Johnford VTC-1600ATC: Ø2,000 mm (Ø78.7 in) of swing over a Ø1,600 mm (Ø63 in) table that carries 8,000 kg (17,600 lb). It is the largest model of the lighter VTC group, the last one before machine weight more than doubles.
That grouping is visible in the maker's table. The VTC-1600ATC weighs 33,000 kg (72,600 lb) and uses a 250 x 250 mm (9.8 x 9.8 in) ram, like the three smaller table-type models. The VTC-2000ATC, one step up, weighs 72,000 kg (158,400 lb). So this is as much diameter as Johnford offers on the lighter structure, and the installation stays manageable: 6,410 x 6,140 x 5,880 mm (252.4 x 241.7 x 231.5 in).
Drive and height come from the VTC-1200ATC. The motor is 37 / 45 kW (49.6 / 60.3 hp), with 45 / 55 kW (60.3 / 73.8 hp) optional, and turning height is 1,250 mm (49.2 in). Torque is higher, 16,204 Nm (11,952 lb-ft), and table speed lower, 2-250 rpm, as a larger diameter requires.
Cross travel is 1,370 mm (53.9 in), which takes the ram from the table centre out past the largest radius. Z is 900 mm (35.4 in) and the cross rail moves 800 mm (31.5 in).
For a shop, the question is usually part weight. Eight tonnes covers most rings, flanges and gear blanks of two metres. A solid forging or a thick-walled casing of that diameter can weigh more, and then the 10,000 kg (22,000 lb) table of the VTC-2000ATC is the safer choice.

Strengths & Limitations
Strengths
- Turns Ø2,000 mm (Ø78.7 in) on a machine of 33,000 kg (72,600 lb)
- 8,000 kg (17,600 lb) table load on a Ø1,600 mm (Ø63 in) table
- 16,204 Nm (11,952 lb-ft) of maximum spindle torque
- 1,250 mm (49.2 in) turning height with 800 mm (31.5 in) of cross rail travel
