How much does the Johnford ST-200B cost?
Price estimate
We do not have a price for the Johnford ST-200B 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
On the Johnford ST-200B a 22 / 26 kW (29.5 / 34.9 hp) spindle sits at the end of a bed with 5,050 mm (198.8 in) of Z travel. The machine weighs 28,100 kg (61,820 lb).
That pairing defines its use. The B spindle is the smallest offered on the long beds: A2-11 nose, 381 mm (15 in) chuck, 132.5 mm (5.2 in) bore, 2,000 rpm. The bed is nearly the longest. So this is not a lathe for heavy rolls, which the C and D versions cover, but for long, comparatively thin shafts where reach matters and cutting forces are moderate. If more power is wanted without the larger spindle, the 30 / 37 kW (40.2 / 49.6 hp) motor is an option.
Tailstock travel is 4,600 mm (181.1 in). The quill is Ø200 mm (7.9 in), MT#7, with 150 mm (5.9 in) of stroke.
The carriage has 370 mm (14.6 in) of X travel, 7 kW servo motors on X and Z, and rapid traverse of 10 m/min and 12 m/min. A full-length traverse is therefore not quick, and programs for a bed this long are best arranged to keep the turret near its work. Outside dimensions are 11,267 x 2,504 x 2,895 mm (443.6 x 98.6 x 114 in).
