Our best estimate for a vertical machining centers (vmc) in this class — not a quote from Okuma. Configuration moves it a long way.

Overview

The Okuma MILLAC 761V II is a 50-taper vertical machining center whose No. 50 (BT 50) spindle turns 20–4,000 rpm as standard. Travels are 1,540 × 760 × 660 mm (60.63 × 29.92 × 25.98 in), and the 1,800 × 720 mm (70.87 × 28.35 in) table takes 2,000 kg (4,400 lbs).

A big taper and a low top speed describe a machine meant for large face mills, heavy drills and long boring bars in steel and cast iron, where a stiff tool connection matters more than surface speed. The standard motor is rated 18.5/15 kW (25/20 hp), and Okuma lists 26/18.5 kW (35/25 hp) as the option. Faster spindles are options too: 30–6,000 rpm, 50–12,000 rpm and 50–15,000 rpm. Nothing on Okuma's page ties a motor to each range, so anyone ordering a high-speed spindle for a job that also includes heavy roughing should get that pairing in writing.

Y travel of 760 mm is a little more than the 720 mm width of the table. The spindle can therefore run past both long edges, and a plate as wide as the table can be faced or edge-milled in one clamping. Lengthwise it is the other way round: the table is 1,800 mm long against 1,540 mm of X, which keeps room at the ends for clamps.

Rapid traverse is 16 m/min (52 fpm). That is half the 32/32/24 m/min X and Y rate of the MILLAC 561V II and well under the 40 / 40 / 30 m/min of the MA-650V, another BT 50 Okuma vertical, which has 660 mm (26.0 in) of Y and Z. On long cuts in heavy parts the rapid rate barely changes the cycle. On parts with many short moves between features it adds up.

Strengths & Limitations

Strengths

No. 50 (BT 50) spindle taper, suited to large-diameter cutters and long boring bars
Y travel of 760 mm (29.9 in) exceeds the 720 mm (28.35 in) table width, so a full-width plate is reachable edge to edge
Table rated for 2,000 kg (4,400 lbs), twice the 1,000 kg of the MILLAC 561V II
Four spindle speed ranges: 20–4,000 rpm standard, with 30–6,000 rpm, 50–12,000 rpm and 50–15,000 rpm as options
Optional 26/18.5 kW (35/25 hp) motor above the standard 18.5/15 kW (25/20 hp)

Limitations

Rapid traverse is 16 m/min (52 fpm), against 40 / 40 / 30 m/min on the MA-650V
The standard spindle stops at 4,000 rpm, which rules out small tools in aluminium unless an optional range is ordered
X travel ends at 1,540 mm (60.6 in); longer parts need the MILLAC 852V II with 2,050 mm (80.7 in)
Okuma's product page states no tool magazine capacity or machine weight, so tooling and foundation planning need the brochure

Frequently Asked Questions

01 What spindle does the Okuma MILLAC 761V II have?

A No. 50 (BT 50) taper spindle. The standard speed range is 20–4,000 rpm on an 18.5/15 kW (25/20 hp) motor. Okuma lists a 26/18.5 kW (35/25 hp) motor and three faster ranges, 30–6,000 rpm, 50–12,000 rpm and 50–15,000 rpm, as options.

02 How large a workpiece fits on the MILLAC 761V II?

The table is 1,800 × 720 mm (70.87 × 28.35 in) and carries 2,000 kg (4,400 lbs). The maximum machining volume matches the travels at 1,540 × 760 × 660 mm (60.63 × 29.92 × 25.98 in). A part can be longer than the X travel and still sit on the table, but only 1,540 mm of it is reachable without moving it.

03 How does the MILLAC 761V II compare with the Okuma MA-650V?

Both use a No. 50 (BT 50) taper and both have 660 mm (26.0 in) of Z. The MA-650V has 660 mm (26.0 in) of Y and 40 / 40 / 30 m/min (131 / 131 / 98 fpm) rapids. The MILLAC 761V II has 760 mm (29.9 in) of Y, a wider 1,800 × 720 mm table against 1,530 × 660 mm, and rapids of 16 m/min (52 fpm).

04 What is the next size up from the MILLAC 761V II?

The MILLAC 852V II, which has 2,050 mm (80.7 in) of X and 850 mm (33.5 in) of Y against 1,540 mm (60.6 in) and 760 mm (29.9 in), and a table rated for 2,500 kg (5,511 lbs) instead of 2,000 kg (4,400 lbs). The taper and the 18.5/15 kW (25/20 hp) standard motor are the same on both.

05 Can the MILLAC 761V II run small tools at high speed?

Not with the standard spindle, which tops out at 4,000 rpm. Okuma lists 50–12,000 rpm and 50–15,000 rpm ranges as options, along with a 30–6,000 rpm range. Check which motor rating comes with the range chosen, because the page lists the 18.5/15 kW and 26/18.5 kW motors separately from the speeds.
