Overview

The Okuma CROWN 762E is an entry-level horizontal CNC turning center built for shops that need reliable, productive turning at a price point well below Okuma's GENOS and LB series. It occupies the bottom rung of Okuma's lathe lineup, targeting job shops, training facilities, and production operations running straightforward 2-axis turning work on steel, aluminum, and stainless steel.

The CROWN 762E swings 375 mm (14.8 in) over the bed with a maximum turning diameter of 305 mm (12 in) and a turning length of 762 mm (30 in)—the number embedded in its name. The spindle delivers 7.5 kW (10 hp) at up to 3,000 RPM through a JIS A2-6 spindle nose, driven through a 2-speed gearbox that provides high torque at low RPM for steel roughing and higher speed for finishing smaller diameters. The 10-inch hydraulic chuck is standard, giving it workholding capacity that belies its entry-level positioning.

The hydraulic turret carries 8 stations and indexes quickly for production work. Rapid traverse rates are 15 m/min on X and 18 m/min on Z—slower than the GENOS and LB lines but adequate for the typical part sizes and cycle times the CROWN targets. The machine uses hardened and ground box ways for long-term geometric accuracy, which sets it apart from some Asian-built entry-level competitors using linear guides.

The OSP-P300L control brings full G-code and One Touch IGF conversational programming capability, giving the CROWN the same programming interface as Okuma's premium lathes. This makes operator cross-training between the CROWN and LB or GENOS machines straightforward. Shops already standardized on Okuma can add a CROWN for lower-complexity work without retraining their workforce.

The CROWN 762E competes with the Haas ST-10, Doosan Lynx 2100, and Mazak Quick Turn 100 in the entry-level production lathe segment. At $50,000-$90,000, it's the most affordable way to run Okuma's OSP control ecosystem. For shops not needing live tooling, Y-axis, or sub-spindle—just accurate, reliable 2-axis turning—the CROWN delivers Okuma reliability at a competitive price.

Strengths & Limitations

Strengths

OSP-P300L control matches Okuma's premium lathes, enabling operator cross-training with no retraining cost
10-inch chuck on an entry-level machine provides workholding capacity usually reserved for larger lathes
Box way construction delivers long-term geometric accuracy that outlasts linear guide competitors in this price class
2-speed gearbox optimizes torque delivery for both heavy roughing and higher-speed finishing
762 mm turning length handles shaft work that smaller compact lathes can't reach
Okuma build quality and vertical integration (in-house spindles, drives, control) reduce integration risk and improve long-term reliability
Lowest-cost entry into the Okuma ecosystem for shops wanting to standardize on OSP controls

Limitations

7.5 kW (10 hp) spindle limits material removal rates in tough materials compared to GENOS and LB series
3,000 RPM max speed restricts high-speed finishing on small-diameter aluminum and brass parts
No live tooling, Y-axis, or sub-spindle options—strictly a 2-axis turning machine
8-station turret is the smallest in Okuma's lineup, limiting tool capacity for complex families of parts
15/18 m/min rapid traverse rates are slower than GENOS and LB series, affecting cycle times on short-cycle parts
OSP control, while capable, has a smaller North American operator pool than Fanuc-based entry-level lathes

Best For

Job shops running straightforward 2-axis turning work on steel, aluminum, and stainless steel Training facilities and vocational schools that want Okuma's OSP control environment at an accessible price Shops standardized on Okuma that need a dedicated roughing or finish-turning machine for simpler parts Small shops entering CNC turning for the first time who want proven reliability without a premium price Production operations running shaft work up to 762 mm length that don't require live tooling or Y-axis Shops that want to add capacity for overflow 2-axis work without the capital outlay of a GENOS or LB machine

Frequently Asked Questions

01 What does an Okuma CROWN 762E cost?

New CROWN 762E machines typically run $50,000-$90,000. The base configuration starts around $50,000-$60,000. Options like high-pressure coolant, chip conveyor, and tool setter push toward the $75,000-$90,000 range. Used CROWN machines sell for $25,000-$45,000 depending on age and condition. It's the lowest-cost entry point into a new Okuma lathe.

02 How does the CROWN 762E compare to the Haas ST-10?

Both are entry-level CNC lathes targeting similar applications. The Okuma CROWN uses box ways versus Haas linear guides, which gives it an edge in long-term geometric accuracy and heavy-cut rigidity. The Haas ST-10 typically costs similar or less and has a much larger North American service network and larger Fanuc-trained operator pool. The Okuma wins on build longevity; the Haas wins on support infrastructure and operator availability.

03 Can the CROWN 762E run bar-fed production?

Yes. The 52 mm bar capacity through the spindle bore accommodates common small-to-mid bar stock. The machine pairs with bar feeders from LNS, Iemca, and Edge Technologies. Without a sub-spindle or parts catcher, you'll need a parts bucket or manual unloading, but the machine itself is capable of extended bar-fed runs.

04 Why does an entry-level lathe have the OSP-P300L control?

Okuma standardizes the OSP-P300L across its turning center lineup. The practical benefit for buyers is that operators can move between a CROWN and a GENOS L3000-e or LB3000 EX III without learning a different control. For shops running multiple Okuma machines, this standardization simplifies training, CAM post-processors, and program management.

05 What's the difference between the CROWN 762E and the GENOS L250II?

The GENOS L250II is a generation newer and more capable: it has an integral spindle motor (no gearbox), Thermo-Friendly Concept thermal compensation, 6,000 RPM versus 3,000 RPM, optional live tooling and Y-axis, and tighter accuracy specs. The CROWN 762E is simpler and cheaper—it's a proven 2-axis platform without the bells and whistles. Choose the CROWN for basic turning at lowest cost; choose the GENOS for higher speed, thermal stability, and multi-axis capability.
