USED OKUMA CROWN 769 – 2000
The OKUMA CROWN 769 – 2000 is a heavy-duty 2-axis CNC turning center designed for large-diameter and long-length turning applications. The CROWN 769 combines a rigid turning-center design with a large work envelope, 30 HP spindle motor, 3,500 RPM maximum spindle speed, programmable tailstock, and Okuma OSP CNC control. Its substantial Z-axis travel makes it particularly suitable for manufacturers machining long shafts, cylinders, rollers, sleeves, and other extended cylindrical components.
The 2000 CROWN 769 provides approximately 24.41 inches of swing, 14.17 inches of maximum turning diameter, and 49.21 inches of machining length. X-axis travel is approximately 9.1 inches, while Z-axis travel is approximately 50.01 inches. The machine can be equipped with a 12-inch chuck and has a documented 3.15-inch bar capacity, providing useful capacity for medium-to-large turning work. Some CROWN 769 configurations are documented with larger 14- or 15-inch chucks, so the exact workholding package should be verified on the individual machine. (cncexchange.com)
The spindle is rated at approximately 30 HP and can reach 3,500 RPM, providing the torque required for heavier turning operations. The machine uses a conventional 2-axis X/Z configuration and does not have Y-axis movement, live tooling, or a sub-spindle. A programmable hydraulic tailstock provides additional support for long workpieces, while the chip conveyor and coolant system help maintain continuous production. (machinio.com)
The OKUMA CROWN 769 – 2000 is particularly suitable for shops machining long and relatively large cylindrical parts. Applications include shafts, hydraulic cylinders, rollers, sleeves, spacers, bushings, flanges, and industrial components. Its large turning capacity and long Z-axis travel make it a practical used CNC lathe for general job shops, heavy equipment manufacturers, oil and gas suppliers, industrial machinery manufacturers, and other production environments.

WHY CHOOSE OKUMA CROWN 769 2000
The OKUMA CROWN 769 – 2000 is a strong choice for manufacturers that need a straightforward, large-capacity CNC turning center rather than a complex multi-tasking machine. Its 50-inch Z-axis travel and approximately 49-inch machining length provide substantial capacity for long workpieces.
The 30 HP spindle and 3,500 RPM maximum speed are well suited to production turning and heavier cutting operations. The 3.15-inch bar capacity also allows the machine to process relatively large bar stock compared with many smaller CNC lathes.
The programmable tailstock is particularly valuable when machining long shafts and cylindrical components because it provides additional workpiece support during turning. The chip conveyor and automatic lubrication system further improve the machine’s suitability for continuous production.

Buying a used OKUMA CROWN 769 2000 can provide a cost-effective way to add a large-capacity CNC lathe to a production shop. The machine’s long machining length and substantial spindle power make it useful for applications that would exceed the capacity of many compact CNC turning centers.
Common valuable features and options to look for include:
- Okuma OSP-U100L control
- OSP-U10L control
- 30 HP spindle
- 3,500 RPM spindle
- 12-inch chuck
- Larger 14- or 15-inch chuck configuration
