How much does the Johnford ST-130B cost?
Price estimate
We do not have a price for the Johnford ST-130B 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
Three metres of travel with a 2,000 rpm spindle: the Johnford ST-130B has 3,050 mm (120.1 in) on Z and is markedly heavier than the shorter models, at 20,100 kg (44,220 lb).
A shaft three metres long and small enough for a 381 mm (15 in) chuck is slender by any measure. Running it near 2,000 rpm between a chuck and a center invites whip and chatter, so this is a size at which the optional steady rests stop being a convenience. The accessory list offers manual or hydraulic self-centering types. The standard support is the tailstock: Ø200 mm (7.9 in) quill, MT#7, with 2,750 mm (108.3 in) of body travel.
The weight tells its own story. The ST-100B, the next size down, is listed at 16,500 kg (36,300 lb), so the three-metre bed is a distinctly heavier structure and not just a stretched one.
Spindle and carriage are unchanged from the shorter B models: A2-11 nose, 132.5 mm (5.2 in) bore, 116 mm (4.6 in) bar capacity, four automatic speeds, 22 / 26 kW (29.5 / 34.9 hp) with 30 / 37 kW (40.2 / 49.6 hp) optional, 370 mm (14.6 in) of X travel and 7 kW axis motors. Length is 8,612 mm (339.1 in).
