The Okuma V920EX-M is a single-saddle CNC vertical turret lathe built around the rigidity and thermal stability that have made Okuma vertical lathes a trusted choice in energy, valve, aerospace, and heavy-equipment shops. This 2024 unit offers a 39.37 inch maximum swing, 36.22 inch maximum turning diameter, and 33.86 inch maximum turning height, with X / Z travels of 19.09 / 33.86 inches and 945 ipm rapid traverse. It carries the high-torque geared spindle option, rated at 60 HP with a 1,000 RPM top speed, on an A2-11 spindle nose with a 4.33 inch bore, and is rated for workpieces up to 2,640 lbs with chuck. The M-spec V12 turret provides 12 stations with a milling function and a 4,000 RPM live milling spindle, so turning, drilling, and milling can be completed in one setup. Workholding is a Kitagawa 36 inch closed-center 3-jaw chuck with adapter plate and hard jaws. Control is the Okuma OSP-P300LA. Equipment includes 230 PSI high pressure coolant, ceiling-mounted shower coolant, a coolant splash gun, a mist collection system, a rear-discharge hinge-type chip conveyor, spare M-codes, and Velocity static and live ER-50 tool kits. Electrical is 220/480V, 3-phase, 60 Hz.
Compared with earlier Okuma vertical lathes such as the V80R, the V920EX-M is a meaningful step forward. Okuma designed the EX series around a compact single-saddle structure that fits a 36-inch-class turning envelope into a smaller footprint, and the current-generation OSP-P300LA control replaces the older OSP-P200L generation with touchscreen operation and Okuma's latest easy-programming tools. The M-spec milling turret adds live-tool capability that lets shops finish keyways, bolt circles, and flats without moving parts to a second machine, while the high-torque geared spindle delivers the low-speed muscle that large-diameter steel work demands. For buyers stepping up from an older Okuma VTL, the V920EX-M is a better machine, not just a newer one.
