Price estimate
We do not have a price for the Johnford ST-130CX 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
Rolls with a barrel of up to a metre are the work of the Johnford ST-130CX: 3,050 mm (120.1 in) of Z travel, 1,000 mm (39.4 in) of swing over the cross slide and the A2-15 spindle with 30 / 37 kW (40.2 / 49.6 hp).
On the two smaller frames a barrel of that size does not fit. The ST-130C clears 700 mm (27.6 in) and the ST-130CH 800 mm (31.5 in) over the cross slide. Roll shops tend to be sized by their largest barrel, and that is the argument for this frame even if most rolls are smaller.
A roll is turned between the chuck and a center. The tailstock here travels 2,750 mm (108.3 in) and has a Ø200 mm (7.9 in) quill with an MT#7 taper. The spindle bearing is 200 mm (7.9 in) in diameter and the chuck 510 mm (20.1 in), or 610 mm (24 in).
Speed is 1,500 rpm with the belt-type gearbox and 1,200 rpm with the geared headstock, on four automatic speeds; a 37 / 45 kW (49.6 / 60.3 hp) motor is optional. X travel is 520 mm (20.5 in). The machine weighs 20,600 kg (45,320 lb) and measures 8,612 x 2,645 x 3,175 mm (339.1 x 104.1 x 125 in).
