Price estimate
We do not have a price for the Johnford ST-160DX 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 ST-160DX is a four-metre lathe with 1,000 mm (39.4 in) of swing over the cross slide and a 185 mm (7.3 in) spindle bore. Its Z travel is 4,050 mm (159.4 in).
Among the machines of this length it stands at one corner of the range: largest frame, largest standard spindle. At the opposite corner is the ST-160B, with 700 mm (27.6 in) of swing over the cross slide, a 132.5 mm (5.2 in) bore and 2,000 rpm. The table puts the ST-160DX at 24,700 kg (54,340 lb) and the ST-160B at 24,100 kg (53,020 lb), which says that the bed and its length, not the frame height or headstock, account for most of what these machines weigh.
The working figures: A2-15 nose, 510 mm (20.1 in) chuck, 165 mm (6.5 in) of bar capacity, 240 mm (9.4 in) bearing, 1,000 rpm, 30 / 37 kW (40.2 / 49.6 hp) with 37 / 45 kW (49.6 / 60.3 hp) optional.
X travel is 520 mm (20.5 in). The tailstock travels 3,600 mm (141.7 in) and its quill is Ø200 mm (7.9 in) with MT#7. Outside dimensions are 9,926 x 2,895 x 3,205 mm (390.8 x 114 x 126.2 in).
