Price estimate
We do not have a price for the Johnford ST-160CX 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-160CX is a four-metre heavy lathe on Johnford's largest ST frame: 4,050 mm (159.4 in) of Z travel, 1,200 mm (47.2 in) of swing over the bed, 1,000 mm (39.4 in) over the cross slide, and the A2-15 spindle.
One figure needs confirming before this model is planned around long work between centers. The tailstock travel that applies to it is best taken from Johnford directly; the neighbouring ST-160BX and ST-160DX, with the same bed, both list 3,600 mm (141.7 in). The quill itself is as on the rest of the frame: Ø200 mm (7.9 in), MT#7, with 150 mm (5.9 in) of travel.
The rest of the specification is clear. A 510 mm (20.1 in) chuck is standard, a 610 mm (24 in) chuck optional. The motor is 30 / 37 kW (40.2 / 49.6 hp), or 37 / 45 kW (49.6 / 60.3 hp), with four automatic speeds; the belt-type gearbox runs to 1,500 rpm and the geared headstock to 1,200 rpm. Bore is 152 mm (6 in) and bar capacity 139 mm (5.5 in).
X travel is 520 mm (20.5 in) on a 7 kW servo motor. The machine weighs 24,500 kg (53,900 lb) and measures 9,926 x 2,895 x 3,205 mm (390.8 x 114 x 126.2 in).
