2012 Okuma MB-66VB CNC Vertical Machining Center

The Okuma MB-66VB is a heavy-duty CNC vertical machining center with a reputation for rigidity and long-haul accuracy that has made it a staple in mold, die, and large-part production environments. This listing features a 59.06" X by 26.38" Y by 24" Z work envelope over a 64.9" x 26" table rated for 3,300 lb loads, paired with a 40 HP CAT 50 spindle running up to 10,000 RPM for aggressive cuts in steel, cast iron, and aerospace alloys, and a high-pressure through-spindle coolant system for deep-pocket drilling and cavity work. The machine's box-way construction, thermally symmetric spindle design, and 20-position arm-style automatic tool changer make it a dependable workhorse for shops running heavy tooling, long program cycles, and tight-tolerance large parts.

The MB-66VB is a meaningful step up from Okuma's predecessor MB-56V line, which offered a noticeably smaller work envelope — typically in the 40–56 inch X-travel class — lower standard spindle horsepower, and the earlier OSP control generation without several of the thermal-compensation and rigidity upgrades introduced on the VB. On the MB-66VB, Okuma stretched the X-travel past 60 inches, beefed up the CAT 50 spindle package to 30 HP, upgraded the column and base castings for greater large-part rigidity, and paired the platform with a refined OSP control experience — meaning shops trading up from an MB-56V get real gains in part capacity, spindle power, and thermal stability, not just a newer nameplate, at a used-machine price.
