Okuma MB-46VA

What the maker publishes about the current Okuma MB-46VA

Okuma groups the MB-46VA with its ACE CENTER MB-V vertical machining centers, and on that page a single column of highlighted figures covers both the MB-46VA and the MB-46VB. In that shared column, the table is 760 × 460 mm and the magazine stores 20 tools. Two spindle speeds appear there, 8,000 and 6,000 min-1, and elsewhere the page gives 8,000 min-1 to the smaller of its two spindle tapers and 6,000 min-1 to the larger. The motor is rated 11/7.5 kW, the larger number for 10 minutes and the smaller for continuous duty. Okuma also prints positioning test data taken on an MB-46VA with AbsoScale fitted, and the strokes named in that test are 560 mm for X, 460 mm for Y and 460 mm for Z. Okuma notes that those test readings are measured examples, not guaranteed figures.
