How much does the Okuma MILLAC 1000VH cost?
Estimated price range
Our best estimate for a 5-axis machining center in this class — not a quote from Okuma. Configuration moves it a long way.
Overview
The Okuma MILLAC 1000VH is a large 5-axis machining center: a 1,000 × 1,000 mm (39.37 × 39.37 in) table carrying up to 2,000 kg (4,400 lbs), with travels of 1,650 / 1,300 / 1,000 mm (64.96 / 51.18 / 39.37 in) on X, Y and Z. Okuma shows a second travel set in brackets, 1,650 / 1,600 / 1,000 mm (64.96 / 62.99 / 39.37 in), which is an option that extends Y.
Two choices define how a particular machine is built. The first is that Y travel, 1,300 mm (51.2 in) as standard or 1,600 mm with the option. The second is the spindle: the standard speed range is 20–6,000 rpm, and a 100–10,000 rpm range is the bracketed alternative. Power is listed as 22/18.5 kW (30/25 hp). The standard spindle, with its 20 rpm floor, is the one for large-diameter cutters and boring in steel and cast iron, while the 10,000 rpm option trades that bottom end for speed with smaller tools. A machine offered from stock should be checked for which of the two it carries.
Rapid traverse is not equal across the axes. X and Y move at 24 m/min (945 ipm) and Z at 12 m/min (473 ipm), so retracts and tool-change clearances on Z take twice as long per unit of distance as moves across the table. On a machine with 1,000 mm of Z that is worth allowing for when estimating cycle times on deep parts.
The MILLAC 800VH is the smaller alternative, with an 800 × 800 mm (31.49 × 31.49 in) table, a 1,000 kg (2,205 lbs) load limit and 30 m/min (1,181 ipm) rapids. The larger machine doubles the table load and is the one to look at when the casting or weldment is too heavy or too wide for the smaller table.

Strengths & Limitations
Strengths
- 2,000 kg (4,400 lbs) table load on a 1,000 × 1,000 mm (39.37 × 39.37 in) table
- Travels of 1,650 / 1,300 / 1,000 mm (64.96 / 51.18 / 39.37 in), with Y extendable to 1,600 mm (62.99 in) as an option
- Standard spindle range starts at 20 rpm and runs to 6,000 rpm, suited to large cutters and boring bars
- Optional 100–10,000 rpm spindle range for work that needs more speed
Limitations
- Z rapid is 12 m/min (473 ipm), half the 24 m/min (945 ipm) of X and Y
- The standard spindle stops at 6,000 rpm; the 100–10,000 rpm range is an option
- The 1,600 mm Y travel is the bracketed option, not the standard 1,300 mm (51.2 in)
- Linear rapids are below the 30 m/min (1,181 ipm) listed for the MILLAC 800VH

Frequently Asked Questions
01
Okuma lists travels as 1,650 / 1,300 / 1,000 mm with a second set, 1,650 / 1,600 / 1,000 mm, in square brackets. The bracketed set is an option: X and Z stay the same and Y grows from 1,300 mm (51.18 in) to 1,600 mm (62.99 in).
02
20–6,000 rpm is the standard range. A 100–10,000 rpm range is shown in brackets as the option. Spindle power is listed as 22/18.5 kW (30/25 hp); Okuma's headline rows do not say whether that rating applies to both ranges, so confirm it for the spindle being ordered.
03
The table is rated for 2,000 kg (4,400 lbs) and measures 1,000 × 1,000 mm (39.37 × 39.37 in). The rating covers the part and its fixture together. The MILLAC 800VH, by comparison, is rated for 1,000 kg (2,205 lbs).
04
24 m/min (945 ipm) on X and Y and 12 m/min (473 ipm) on Z. The Z rate is half that of the other two axes, which lengthens retract and approach moves on tall parts.
