What the maker publishes about the current Okuma MB-56VA
A double-column frame carries the Okuma MB-56VA, a vertical machining center. Its 40-taper spindle turns 50 to 8,000 rpm and is driven by an integral VAC motor rated 15/10 hp, with spindle cooling that runs in both directions. Okuma's page puts 15,000 rpm and faster spindles among the options. A 20-position automatic tool changer serves the spindle, and rapids reach 1,575 ipm for X and Y, 1,260 ipm for Z. For X, Y and Z, Okuma gives a maximum machining volume of 41.34, 22.05 and 18.11 in, over a table of 22.05 x 51.18 in. Okuma's page also lists its Thermo-Friendly Concept as standard equipment on the MB-56VA, to hold size through long runs.

What the Okuma MB-56VA is used for
Okuma's MB-56V page names aluminum at one end and metals that are hard to cut at the other as the materials the machine takes on, and ties its spindles and stiff frame to heavy cuts.

What fits an Okuma MB-56VA
Each of these follows from a published specification above, which is named beside it.
40-taper toolholders
This is a 40-taper spindle — the 7:24 steep taper that CAT-40, BT-40 and DIN 69871 (SK-40) holders all share. They share the taper and nothing else that matters: the retention knob and the flange form differ between those standards, so holders do not swap between them without changing pull studs. Knowing which standard a machine was tooled for is worth doing before the holders are packed.
Derived from Spindle taper: 40 taper
What to check on an Okuma MB-56VA
- Spindle. The manufacturer gives a spindle speed of 8,000 min⁻¹ (standard; 15,000 to 35,000 optional). Run the spindle to top speed and listen for bearing noise.
- Spindle load. The manufacturer gives 11/7.5 kW (standard spindle) of spindle power. Take a heavy cut and watch the load meter.
- Spindle taper. The manufacturer gives a spindle taper of 40 taper. Check it for fretting and that the drawbar holds a tool.
- Axes and way covers. The manufacturer gives X 1,050 mm, Y 560 mm and Z 460 mm of travel. Run each axis end to end and check the way covers.
- Rapids and ballscrews. The manufacturer gives a rapid traverse of X-Y 40, Z 32 m/min. Measure the backlash on each axis.
- Tool changer. The manufacturer gives the tool capacity as 20. Cycle every pocket and watch for a hesitation.
- Table. The manufacturer gives a table size of 1,300 x 560 mm. Check the table and its T-slots for damage.
