How much does the Johnford ST-200BH cost?
Price estimate
We do not have a price for the Johnford ST-200BH 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
Installing a Johnford ST-200BH is a building question before it is a machining one. The lathe is 11,267 mm (443.6 in) long, 2,504 mm (98.6 in) wide and 2,955 mm (116.3 in) high, and weighs 28,200 kg (62,040 lb).
What that buys is 5,050 mm (198.8 in) of Z travel under a swing of 1,000 mm (39.4 in) over the bed and 800 mm (31.5 in) over the cross slide. Parts of that size are loaded by crane, and the layout needs to allow for that: clear access above the bed, space at the tailstock end for the tailstock to run back over its 4,600 mm (181.1 in) of travel, and room for the chain type chip conveyor and its trolley.
The ST accessory list does not mention foundation bolts or levelling pads, so the foundation drawing is something to request early.
The working end is the B spindle: 381 mm (15 in) chuck, 132.5 mm (5.2 in) bore, 2,000 rpm, 22 / 26 kW (29.5 / 34.9 hp) or optionally 30 / 37 kW (40.2 / 49.6 hp). X travel is 420 mm (16.5 in), and the X and Z axes have 7 kW servo motors with rapids of 10 m/min and 12 m/min.
