How much does the Toshiba FMB-2000 cost?
Estimated price range
Our best estimate for a cnc boring machine in this class — not a quote from Shibaura Machine. Configuration moves it a long way.
Overview
The Toshiba FMB-2000 is listed as a very large boring machine: a 200 mm (7.9 in) spindle, X floor travel of up to 20,000 mm (787 in), 5,000 mm (197 in) of vertical Y travel and a complete system weight of about 350,000 kg (771,617 lb). It is not on Shibaura Machine's current pages, so the listed figures should be confirmed against the documentation of the machine in question.
Reach toward the work comes from 2,000 mm (78.7 in) of Z cross travel and a 1,500 mm (59 in) W-axis quill. A quill stroke that long is for bores deep inside large fabrications and castings, the kind of part that stays on the floor while the machine travels along it. The X figure is stated as an upper limit, so a given machine may have been built shorter.
The spindle is listed at 1 to 1,000 rpm with 55 kW (73.8 hp). The slow range suits large-diameter boring and facing tools, and the table also lists a PAL type facing and boring head for diameters up to 3,000 mm. For comparison, the BSF-150C lists 10-3,500 rpm and AC 37/30 kW (50/40 hp), a faster and lighter spindle. Positioning accuracy is listed as ± 0.012 mm and the control as Fanuc 30iM / Siemens 840D sl.

Strengths & Limitations
Strengths
- X floor travel listed at up to 20,000 mm (787 in), with 5,000 mm (197 in) of vertical travel
- 200 mm (7.9 in) spindle with a 1,500 mm (59 in) W-axis quill for deep bores
- 55 kW (73.8 hp) of listed spindle power
- PAL type facing and boring head listed for diameters up to 3,000 mm
Limitations
- Spindle speed is limited to 1,000 rpm, so small tools cannot be run at a useful cutting speed
- A complete system weight of about 350,000 kg (771,617 lb) calls for a purpose-built foundation
- Positioning accuracy is listed as ± 0.012 mm, which has to be weighed against the tolerance of the bores being machined
- Not on Shibaura Machine's current pages, and no tool magazine, rapid traverse or work table rows are listed

Frequently Asked Questions
01
The listed travels are up to 20,000 mm (787 in) of X floor travel, 5,000 mm (197 in) of vertical Y travel and 2,000 mm (78.7 in) of Z cross travel, plus a 1,500 mm (59 in) quill in W. The complete system is listed at about 350,000 kg (771,617 lb). X is an upper limit, so check the travel of the individual machine.
02
The listed figures are a 200 mm (7.9 in) spindle diameter, 1 to 1,000 rpm and 55 kW (73.8 hp). No torque or taper row is listed. The speed range is a low one, which fits large boring bars and facing heads and excludes small-tool work.
03
The table lists a PAL type facing and boring head for diameters up to 3,000 mm. It does not explain the head further or say whether it is standard, so on any machine being assessed it is worth confirming that the head is present and which tooling comes with it.
04
The control row reads Fanuc 30iM / Siemens 840D sl, so either may be fitted and the machine itself has to be checked. Positioning accuracy is listed as ± 0.012 mm. No repeatability figure is given, and the model is not on Shibaura Machine's current pages, so treat both rows as figures to confirm.
