Overview

The Okuma MB-46VAE is a BT 40 vertical machining center with 560 mm (22.0 in) of X travel and 460 mm (18.1 in) in both Y and Z, working over a 760 x 460 mm (29.9 x 18.1 in) table rated for 500 kg (1,102 lb). On the listed figures its travel envelope is the same as that of the MB-46V II.

Where the two differ on paper is speed. The listed rapids here are 32 m/min in X and Y and 24 m/min in Z, against 42/36 m/min for the MB-46V II. The standard spindle is 8,000 rpm with an 11/7.5 kW (15/10 hp) motor; spindles of 15,000, 20,000, 25,000 and 35,000 rpm and a 22/18.5 kW (30/25 hp) motor are listed as options.

The listed figures describe hand-scraped box ways on all axes and the OSP-P300A control. Positioning accuracy is given as ±0.004 mm and repeatability as ±0.002 mm, and the machine weighs 4,600 kg (10,141 lb). The magazine holds 20 tools as standard, with 32, 48 or 98 optional. When looking at a particular machine, check which spindle, motor and magazine it was built with, because those options change what it can do far more than the base figures suggest.

Strengths & Limitations

Strengths

Listed positioning accuracy of ±0.004 mm and repeatability of ±0.002 mm
Box ways on all axes, hand-scraped, according to the listed figures
500 kg (1,102 lb) table load on a 760 x 460 mm (29.9 x 18.1 in) table
Spindle options run from the standard 8,000 rpm up to 35,000 rpm
Magazine options of 32, 48 or 98 tools beyond the standard 20

Limitations

Listed rapids of 32 m/min (X/Y) and 24 m/min (Z) are below the 42/36 m/min of the MB-46V II
The standard motor is 11/7.5 kW (15/10 hp); the 22/18.5 kW (30/25 hp) motor is an option
X travel of 560 mm (22.0 in) is shorter than the 760 mm table, so the table ends cannot be machined
The standard spindle stops at 8,000 rpm, and every faster spindle is an option

Best For

Small precision parts within 560 mm of X and 460 mm of Y and Z Workpieces and fixtures up to 500 kg (1,102 lb) Fine finishing where the listed ±0.002 mm repeatability matters High-speed small-tool work when an optional spindle is fitted

Frequently Asked Questions

01 What is the difference between the MB-46VAE and the MB-46V II?

On the listed figures the travels are the same, 560 mm (22.0 in) in X and 460 mm (18.1 in) in Y and Z, and both start with a 20-tool magazine. The MB-46V II is listed with faster rapids, 42/36 m/min against 32 m/min (X/Y) and 24 m/min (Z) here. The MB-46VAE figures also include a 98-tool magazine option and spindles up to 35,000 rpm.

02 What spindle options does the MB-46VAE have?

The standard spindle is BT 40 at 8,000 rpm with an 11/7.5 kW (15/10 hp) motor. The listed options are 15,000, 20,000, 25,000 and 35,000 rpm spindles and a 22/18.5 kW (30/25 hp) motor. On a used machine, read the spindle and motor from the build sheet, since the option fitted decides what work it suits.

03 How much weight can the MB-46VAE table carry?

The listed table load is 500 kg (1,102 lb) on a 760 x 460 mm (29.9 x 18.1 in) table. Count the vise or fixture plate and any rotary table in that total. The machine itself is listed at 4,600 kg (10,141 lb), which is the figure to give a rigger and to check against the floor.

04 What control and guideways does the MB-46VAE use?

The listed control is Okuma's OSP-P300A. The guideways are listed as box ways on all axes, hand-scraped. Listed positioning accuracy is ±0.004 mm, with ±0.002 mm repeatability.
