How much does the Johnford ST-200CH cost?
Price estimate
We do not have a price for the Johnford ST-200CH 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
Five metres of travel under 800 mm (31.5 in) of swing over the cross slide, with the A2-15 spindle: the Johnford ST-200CH is built for long rolls with a large barrel.
The relevant comparison is with the ST-200C, which has the same length and spindle but 700 mm (27.6 in) over the cross slide and 370 mm (14.6 in) of X travel. A barrel that will not pass the smaller carriage needs this frame, and the weight penalty is small: 28,400 kg (62,480 lb) against 28,200 kg (62,040 lb) for the ST-200C.
Z travel is 5,050 mm (198.8 in) and tailstock travel 4,600 mm (181.1 in). The quill is Ø200 mm (7.9 in), MT#7, with 150 mm (5.9 in) of stroke.
A 510 mm (20.1 in) chuck is standard and a 610 mm (24 in) chuck optional. The drive is 30 / 37 kW (40.2 / 49.6 hp), or 37 / 45 kW (49.6 / 60.3 hp), through four automatic speeds; top speed is 1,500 rpm with the belt-type gearbox and 1,200 rpm with the geared headstock. X travel is 420 mm (16.5 in) on a 7 kW servo motor. Outside dimensions are 11,267 x 2,504 x 2,955 mm (443.6 x 98.6 x 116.3 in).
