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 MB-46V II is a small-envelope vertical machining center with 560 × 460 × 460 mm (22.05 × 18.11 × 18.11 in) of travel over a 460 × 760 mm (18.11 × 29.92 in) table. The table is longer than the X stroke, 760 mm against 560 mm, so the spindle cannot reach the full table length; the outer ends are room for clamps and overhang, not machining area. In Y the 460 mm stroke equals the table width.

Rapid traverse is 42 m/min (1,654 ipm) in X and Y and 36 m/min (1,417 ipm) in Z. The MB-56V, the next machine up with 1,050 mm (41.3 in) of X, is given 40 m/min in X-Y and 32 m/min in Z, so the smaller machine is the quicker of the two on paper. With strokes this short the axes spend most of a move accelerating, and the gain shows mainly in tool-change approaches and Z retracts.

The spindle row reads 15,000 [6,000] rpm: 15,000 rpm is the listed speed and 6,000 rpm, in brackets, is the alternative. Two motor ratings appear, 11/7.5 kW (15/10 hp) and 22/18.5 kW (30/25 hp). Okuma's horsepower row puts 15/10 hp first with 30/25 hp bracketed as the option, while the kilowatt row brackets the smaller motor instead, so ask which motor is on the quotation instead of assuming.

The magazine holds 20 tools as standard, with 32 and 48 as options. Okuma's product page states no taper, table load or machine weight for this model, and those figures are needed before fixtures and tooling are planned.

Strengths & Limitations

Strengths

Rapids of 42 m/min (1,654 ipm) in X and Y and 36 m/min (1,417 ipm) in Z
15,000 rpm listed spindle speed for small cutters and finishing passes
Y travel of 460 mm (18.1 in) equals the table width, so the full depth of the table is within reach
Magazine can be ordered with 32 or 48 tools in place of the standard 20
A 22/18.5 kW (30/25 hp) spindle motor is listed alongside the 11/7.5 kW (15/10 hp) one

Limitations

X travel is 560 mm (22.0 in) on a 760 mm long table, so the ends of the table lie outside the cutting envelope
Okuma's two power rows disagree on which motor is the standard one, so the motor has to be confirmed on the quotation
Longer parts need the MB-56V, which has 1,050 mm (41.3 in) of X and 560 mm (22.0 in) of Y
No taper, table load or machine weight appears among the published rows

Best For

Small prismatic parts that fit inside 560 × 460 × 460 mm of travel High-speed finishing with small tools at 15,000 rpm Short-cycle work where 42 m/min X-Y rapids trim non-cutting time Jobs needing up to 48 tools with the optional magazine

Frequently Asked Questions

01 What are the travels of the Okuma MB-46V II?

X is 560 mm (22.0 in), Y is 460 mm (18.1 in) and Z is 460 mm (18.1 in). Okuma gives the maximum machining volume as 560 × 460 × 460 mm (22.05 × 18.11 × 18.11 in). The table measures 460 × 760 mm (18.11 × 29.92 in), which is longer than the X stroke, so the full table length cannot be machined in one setup.

02 How fast is the MB-46V II spindle?

The spindle speed row reads 15,000 [6,000] rpm. The first figure, 15,000 rpm, is the listed speed; the bracketed 6,000 rpm is the alternative spindle. A 6,000 rpm limit is enough for larger cutters in steel and iron but slows small-tool work, so choose according to the tool diameters the jobs call for.

03 How many tools does the MB-46V II hold?

20 tools in the standard magazine. Okuma lists 32-tool and 48-tool magazines as options. Decide at order time: jobs that keep duplicate tools or several part families loaded will fill 20 pockets quickly.

04 How does the MB-46V II compare with the MB-56V?

The MB-56V is the longer machine: 1,050 mm (41.3 in) of X and 560 mm (22.0 in) of Y against 560 mm and 460 mm here, with the same 460 mm (18.1 in) of Z and the same 20, 32 or 48 tool choices. The MB-56V lists rapids of 40 m/min in X-Y and 32 m/min in Z, slightly below the 42 and 36 m/min of the MB-46V II.

05 What spindle motor does the MB-46V II have?

Two ratings are listed: 11/7.5 kW (15/10 hp) and 22/18.5 kW (30/25 hp). The horsepower row shows 15/10 hp as the base figure with 30/25 hp in brackets; the kilowatt row brackets the smaller motor instead. Because the two rows do not agree on which is standard, confirm the motor with Okuma when specifying the machine.
