Price estimate
We do not have a price for the Johnford ST-130EX+B+C+Y 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
Built around a Ø235 mm (9.3 in) spindle bore and a manual 3-jaw chuck of Ø740 mm, the Johnford ST-130EX+B+C+Y is the slow, large-bore member of the ST Turn-Mill group. Distance between centers is 3,050 mm (120.1 in).
Its main spindle runs at no more than 500 rpm, the lowest speed in the table. With an A2-15 nose, an auto 4-speed gearbox and 30 / 37 kW (40.2 / 49.6 hp), the drive is geared for torque on large diameters; turning capacity is Ø850 mm (33.5 in) and bar capacity Ø204 mm (8 in).
Note the chuck. The page's standard accessory list names a 3-jaw hydraulic through-hole chuck, but this column specifies a manual one. For heavy, irregular or one-off workpieces that is a normal choice; for repeated loading it adds time at every part change.
Milling capacity matches the rest of the group: HSK-A100, 38 / 62 kW (51.0 / 83.1 hp), 6,000 rpm, a 40-tool magazine and tools up to 450 mm (17.7 in) long. X travel is +836 / -10 mm, the longest X in the table, and Y is ±100 mm (±3.9 in) with a Y rapid of 2.3 m/min. The machine weighs 55,000 kg (121,252 lb) and measures 10,632 x 5,789 x 4,839 mm (418.6 x 227.9 x 190.5 in).

Frequently Asked Questions
01
The table does not explain it, but the figure goes with the bore: Ø235 mm (9.3 in), the second largest in the group. The ST-160FX+B+C+Y, with a Ø255 mm (10 in) bore, is listed at 600 rpm.
02
The specification table lists a manual 3-jaw chuck of Ø740 mm for this model. That differs from the page's general accessory list, so the chuck is a point to confirm with Johnford when ordering.
03
X +836 / -10 mm, Y ±100 mm (±3.9 in) and Z 3,050 mm (120.1 in). Rapid traverse is 10 / 2.3 / 12 m/min on X, Y and Z. The tailstock travels 2,800 mm (110.2 in).
04
The standard accessory list for the ST Turn-Mill names a Fanuc 31-TB PLUS or Siemens SINUMERIK ONE with a 15” color screen display and a 4+1 axis machining package. A simultaneous 5-axis machining package is optional.
