Estimated price range
Our best estimate for a vertical machining centers (vmc) in this class — not a quote from Kuraki. Configuration moves it a long way.
Overview
The Kuraki KM-6VA is a large vertical machining center with 2,000 x 1,000 x 800 mm (78.7 x 39.4 x 31.5 in) of travel over a 2,000 x 1,000 mm (78.7 x 39.4 in) table that takes workpieces up to 5,000 kg (11,023 lb). The model is not in the maker's current lineup and may be an older one. Nothing here has been checked against a manufacturer page, so these are the listed figures only.
Travel and table are the same size in X and Y, which means the spindle reaches the whole table surface and a plate as large as the table can be machined edge to edge. With 800 mm (31.5 in) of Z there is room for tall fixtures or deep mold blocks.
The spindle is rated 30 kW (40.2 hp) and 350 Nm, at 8,000 RPM with 12,000 RPM optional. Taper is HSK-A63, with HSK-A100 optional. Those two options pull in different directions, the faster spindle toward finishing with small tools and the larger taper toward heavy cutters, so find out which combination a machine was built with. The magazine holds 40 tools and is expandable to 80.
Rapid traverse is 24 m/min (945 ipm) in X and Y and 20 m/min (787 ipm) in Z. Positioning accuracy is listed as 0.007 mm over the full stroke (7 µm) and flatness as 0.02 mm over the full table (20 µm). The control is a Fanuc 31i-B5, and the machine weighs 22,000 kg (48,502 lb).

Strengths & Limitations
Strengths
- X and Y travel of 2,000 x 1,000 mm (78.7 x 39.4 in) match the table size, so the full table can be machined
- Spindle rated 30 kW (40.2 hp) and 350 Nm
- Positioning accuracy of 0.007 mm over the full stroke (7 µm)
- 40 tools as listed, expandable to 80
- Workpiece weight up to 5,000 kg (11,023 lb)
Limitations
- 12,000 RPM is optional; the listed spindle speed is 8,000 RPM
- HSK-A100 is an option, and HSK-A63 holders do not fit it, so tooling depends on the build
- Machine weight of 22,000 kg (48,502 lb) calls for a prepared foundation and heavy rigging
- Z rapid of 20 m/min (787 ipm) is slower than the 24 m/min (945 ipm) of X and Y

Frequently Asked Questions
01
Travels are 2,000 mm (78.7 in) in X, 1,000 mm (39.4 in) in Y and 800 mm (31.5 in) in Z, over a table of 2,000 x 1,000 mm (78.7 x 39.4 in). Maximum workpiece weight is 5,000 kg (11,023 lb). The figures are unverified and should be measured on the machine.
02
The listed spindle is 30 kW (40.2 hp) and 350 Nm at 8,000 RPM with an HSK-A63 taper. A 12,000 RPM spindle and an HSK-A100 taper are both listed as optional. The table does not say whether the power and torque figures apply to the optional versions.
03
Positioning accuracy is listed as 0.007 mm over the full stroke (7 µm) and flatness accuracy as 0.02 mm over the full table (20 µm). Repeatability is not listed. On an older machine these are as-built figures, so ask for a recent laser or ballbar check.
04
Tool capacity is listed as 40, expandable to 80. Maximum tool diameter, length and weight are not given, and they differ between the HSK-A63 and the optional HSK-A100 taper, so take them from the machine's documentation.
