What to Look for When Buying a Used Okuma
Okuma machines are known for heavy cast iron construction, thermal stability, and the proprietary OSP CNC control. Single Source engineering (in-house motors, drives, spindles, encoders, and controls) makes Okuma one of the most reliable choices on the used market.
Check spindle, turret, and ballscrews on turning centers. Measure spindle runout and listen for bearing noise across the full RPM range. On live-tool turrets (M and MY-suffix models), verify each station for smooth rotation and full torque. On twin-turret LT machines, test synchronized cutting. On sub-spindle W-suffix machines, test the handoff and C-axis indexing. Check ballscrew backlash on all axes.
Verify spindle, ATC, and axes on machining centers. Test spindle runout, bearing noise, and thermal growth after warm-up. Cycle the tool changer through every pocket. On 5-axis models (GENOS M460V-5AX, M560V-5AX, MU series), verify trunnion accuracy and simultaneous 5-axis calibration.
Confirm the OSP control generation. Older machines may carry OSP5000, OSP7000, OSP-U10/U100, or OSP-E100. Current machines run OSP-P200, OSP-P300, or OSP-P500 with the THINC platform. Control generation affects training and programming compatibility.
Okuma Turning Centers
LB Series (Production Lathes)
The LB series (LB2000 EXII, LB3000 EXII, LB4000 EXII, LB35III, LB45III) is Okuma's flagship turning platform and the most widely traded Okuma lathe on the used market. High-rigidity construction, heavy-duty integral spindles, and optional Y-axis or sub-spindle configurations (MY, MYW, BB variants). The LB3000 EX is the most common used-market model.
GENOS L Series
The GENOS L series (L200, L250, L300, L300M, L3000, L3000-MY) delivers value-priced production turning with full Okuma rigidity and OSP control. The GENOS L3000 and L300M are common used-market finds.
LT Twin-Turret & LU Heavy-Duty
The LT series (LT2000 EX, LT3000 EX) features twin turrets for high-production turning. The LU series (LU15, LU35II, LU45II, LU3000 EX, LU4000 EX, LU7000 EX) delivers heavy-duty, large-bore turning for oil country and heavy-workpiece work.
V Series & VTM (Vertical Turning)
The V series (V40R, V100R, V760EX, V920EX) and VTM series (VTM-65, VTM-100, VTM-200) handle large-diameter workpieces. VTM models add full milling for done-in-one machining.
Okuma Machining Centers
GENOS M & MB Vertical Machining Centers
The GENOS M series (M460V, M560V, M560VE, M660V) provides cost-effective VMCs with 30 HP spindles, CAT 40 tapers, and 32-to-48 tool ATCs. The MB-V series (MB-46V, MB-56V, MB-66V, MB-80V) targets larger, more demanding production work.
MA & MB Horizontal Machining Centers
The MA-H and MB-H series (MB-4000H, MB-5000H, MB-8000H) are Okuma's horizontal platforms with built-in pallet changers, high tool capacity, and rigid box-way construction for long-run production.
5-Axis & Double-Column
The GENOS M460V-5AX and M560V-5AX deliver trunnion-table 5-axis machining. The MU series (MU-400V, MU-500V, MU-5000V, MU-6300V) covers mid-size to large universal machining. MCR double-column machines serve large die, mold, and aerospace work.
Okuma Multitasking & Specialty
The MULTUS B series (B200II, B250II, B300II, B400II, B550, B750) combines turning with a tilting B-axis milling spindle for done-in-one machining. The MULTUS U series (U3000, U4000, U5000) handles larger multitasking work. Legacy MACTURN machines (250W, 350W) remain on the used market. Okuma also produces GA/GI/GP grinders and 2SP twin-spindle lathes.

Frequently Asked Questions About Used Okuma Machines
Are used Okuma machines reliable?
Yes. Okuma's Single Source philosophy (in-house controls, spindles, motors, drives, and encoders) eliminates compatibility issues and delivers long service life. Many machines from the 1990s and early 2000s remain in full production today.
What CNC control does Okuma use?
Okuma uses its proprietary OSP control on every machine. Current generations include OSP-P200, OSP-P300, and OSP-P500 with the THINC platform. Legacy machines may carry OSP5000, OSP7000, OSP-U10/U100, or OSP-E100. OSP offers closed-loop absolute positioning, IGF conversational programming, and User Task macros.
How does OSP differ from Fanuc or Siemens?
Fanuc and Siemens are third-party controls used by most other builders. OSP is Okuma's own control, integrated natively with Okuma servos, spindles, and encoders. Operator training matters when buying used.
What Okuma models hold their value best?
LB-series lathes, MULTUS B multitasking machines, GENOS L and GENOS M platforms, LT twin-turret lathes, and MB-H horizontals. Machines with OSP-P controls command a premium. Call (844) 478-8181 for valuations.
Where are Okuma machines manufactured?
Okuma machines are built in Oguchi, Japan. North American support comes from Okuma America in Charlotte, NC.
