How much does the Johnford VTC-1200ATC cost?
Price estimate
We do not have a price for the Johnford VTC-1200ATC 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 Johnford VTC-1200ATC is the first VTC model built for tall parts. Maximum turning height is 1,250 mm (49.2 in), and the cross rail travels 800 mm (31.5 in), twice the stroke of the two smaller table-type machines. Turning diameter is Ø1,600 mm (Ø63 in) on a Ø1,250 mm (Ø49.2 in) table.
Cross rail travel is easy to overlook in a specification, and it shouldn't be. The ram of a vertical lathe is stiffest when it is short. A rail that can come down 800 mm lets the operator machine a low ring with the ram barely extended and then lift the rail for a part more than a metre tall, without changing anything else. Ram travel itself is 900 mm (35.4 in).
The table carries 5,000 kg (11,000 lb) and turns at 2-350 rpm. Drive power is 37 / 45 kW (49.6 / 60.3 hp), or 45 / 55 kW (60.3 / 73.8 hp) as an option, and maximum torque is 11,179 Nm (8,246 lb-ft). That torque figure is only a little above the VTC-1000ATC's 10,049 Nm (7,412 lb-ft); what the larger machine adds is diameter, height and motor power.
Typical parts are tall as well as wide: large valve bodies, compressor casings, bearing housings for wind and marine drives, hydraulic cylinder ends. With the optional 2-2,400 rpm power spindle and C-axis, flange holes and keyways are finished on the same table.
The machine is 6,035 x 5,820 x 5,870 mm (237.6 x 229.1 x 231.1 in) and weighs 30,000 kg (66,000 lb).

Frequently Asked Questions
01
Up to 1,250 mm (49.2 in). The ram travels 900 mm (35.4 in) in Z and the cross rail a further 800 mm (31.5 in) in W.
02
The work table is Ø1,250 mm (Ø49.2 in) and carries 5,000 kg (11,000 lb). It comes with 4 independent jaws as standard, and a 4-jaw hydraulic chuck is an optional accessory.
03
The VTC-1600ATC: Ø2,000 mm (Ø78.7 in) turning diameter, a Ø1,600 mm (Ø63 in) table for 8,000 kg (17,600 lb) and 16,204 Nm (11,952 lb-ft) of torque. Turning height, cross rail travel and motor power are the same as on the VTC-1200ATC.
04
Rapid traverse is 12 / 10 m/min (472 / 394 ipm) in X and Z. The X and Z servo motors are 7 / 7 kW, and the cross rail is raised and lowered by a 7.5 kW motor.
