A compact lathe suitable for mass production. The highly stable machining accuracies and compact body really deliver high productivity. The GENOS L II series achieves the best cost performance customers require for high machining performance, accuracy, and ease of use. Applicable workpieces GENOS L II machines handle workpieces with diverse shapes. Gear blanks Output shaft Input shaft Improve productivity A compact lathe with machine width of 1,400 mm* (GENOS L250II DBC 290) specifically for turning. The slideway for the turret is a slide guideway to support loads during powerful cutting and raise productivity. In addition, the feed rate is 20% faster than the previous machine, and non-cutting time is shorter. * Cylinder cover, operation panel not included. Ease of use in any shop floor was a thoroughly pursued objective The machines were structurally designed to have easy access to the spindle and good maintainability. The coolant tank is separated, so the tank can be washed without removing the chip conveyor. In addition, the chip discharge outlet is 1.8 times larger than before, which keeps chip build-up low and machine-stop cleaning time short during continuous, long-run operations. Mass production lines also compact In combination with loaders and stockers, mass production system layouts can be flexibly arranged. Even a large number of machines lined up in mass production factories can also be kept compact and efficient. As the number of machines increase, the space-saving machine design itself will become a more valuable benefit. Okuma’s Intelligent Technology reduces operator burden Thermo Active Stabilizer – Construction (TAS-C) is used to support dimensional stability at high levels during cycle start and machining restart, and of course during continuous operation. This significantly reduces man-hours for controlling dimensions. With graphic visualization of machining status provided by Machining Navi (option), any operator can easily use the machine and cutting tools to their fullest. 3 4 Improve productivity Ease of use in any shop floor was a thoroughly pursued objective Productivity increases with compact, high-speed operations Structurally designed with good accessability Turret (turning operations) V8 and V12 turrets are available. Compared to the previous model, productivity improves with faster feed rates for each axis. Machine width: 1,400 mm* (GENOS L250II DBC 290). The highly rigid structural design supports powerful cutting loads to offer high productivity. Boring bars of ø32 mm or ø40 mm can be attached. * Cylinder cover, operation panel not included. Outstanding chip discharge The spindle centerline is just 260 mm from the front of the machine for easy access and reduced operator workload. The low 1,669-mm machine height also allows operators to easily see other machines and operators nearby. (GENOS L250II) The chip discharge outlet is 1.8 times larger than on previous machines, minimizing chip accumulation. The cleaning frequency is reduced for maximum operation time.

Okuma's selection of workpiece tables, part turnover stands, post-process gauges and other peripherals, can provide an ideal system arrangement to meet your needs. OGL5-0II (option) Varying the spindle speed in accordance with the best amplitude and period makes it possible to suppress chatter during turning operations. Tool life can be extended and machining time reduced with use of the optimum cutting conditions, producing significant effects in drilling/boring bar, threading, and grooving applications. When chattering occurred during threading, it was common to lower the cutting conditions or use special tools that resist chattering. Okuma’s Machining Navi T-g (threading) breaks the vibration periodicity with a different spindle speed for each threading pass, and suppresses chatter growth. The machining capacity of your normally used tools can be maximized for stable machining.

(option) ■ Part program create ■ Advanced run Simply inputting data on the machining shape in an interactive way will automatically determine the machining processes and create a part program. To run the machine directly from the interactive part program screen. When a problem is detected it can be quickly corrected and checked, speeding up first part machining. Smart factories are using advanced digitization and networking (IIoT) in manufacturing to achieve enhanced productivity and added value. The OSP has evolved tremendously as a CNC suited to advanced intelligent technology. Okuma’s new control uses the latest CPUs for a tremendous boost in operability, rendering performance, and processing speed. The OSP suite also features a full range of useful apps that could only come from a machine tool manufacturer, making smart manufacturing a reality. Machining shape Directly change cutting conditions for each operation with this process sheet Smooth, comfortable operation with the feeling Smooth of using a smartphone operations even with wet or work-gloved hands Improved rendering performance and use of a multi-touch panel achieve intuitive graphical operation. Moving, enlarging, reducing, and rotating 3D models, as well as list views of tool data, programs, and other information can be accomplished through smooth, speedy operations with the same feel as using a smartphone. The screen display layout on the operation screen can also be changed to suit operator preferences and customized for the novice and/or veteran machinists. Enlarge Reduce Tables make it easy to make mid-cycle or individual process starts “Just what we wanted.”— Refreshed OSP suite apps Continuous run This became possible through the addition of Okuma's machining expertise based on requests we heard from real, machine-shop customers. The brain power packed into the CNC, built by a machine tool manufacturer, will “empower shop floor” management. Spindle Output Monitor Increased productivity through visualization of motor power reserve The specified spindle output (red line: short time rating, green line: continuous rating) and the spindle output in current cutting (blue circle) are simultaneously displayed on the screen, for real-time view of power reserve during cutting. This allows speeding up cutting by increasing the spindle speed or feed rate while monitoring the graph to ensure that the blue circle does not cross the lines. Individual run (machining repeated with this tool only) Easy to Operate ■ Operation screen split into four displays ■ Tool registration Simultaneous display includes setup work, current position needed in confirming movement in trial machining, NC program, and graphic simulation. Register data for all of your tools. Since the registered tool data is also used by Okuma auto programming (Advanced One-Touch IGF) and a collision check function (Collision Avoidance System), this screen will complete the entire registering process. When loading a tool in the machine, simply match it to each turret station from among the registered tools. ■ Forming soft jaws ■ Zero offsets Templates like this make it easy to set required jaw shape, tool, and cutting conditions. Part programming not required to do this. A simple function key operation is all it takes to shift a zero offset to either the left or right end of a workpiece. The required zero offset will be calculated automatically based on jaw and workpiece lengths. (when the tool offset is set with reference to the turret tool mounting surface) E-mail Notification Scheduled Program Editor Mid-cycle start (finishing repeated) Monitoring utilization status even when away from the machine Easy programing without keying in code Get Connected, Get Started, and Get Innovative with Okuma “Monozukuri” Machine tool and PC Connect, Visualize, Improve Okuma’s Connect Plan is a system that provides analytics for improved utilization by connecting machine tools and visual control of factory operation results and machining records. Simply connect the OSP and a PC and install Connect Plan on the PC to see the machine operation status from the shop floor, from an office, from anywhere. The Connect Plan is an ideal solution for customers trying to raise their machine utilization. 9 Connect 10 ■ Machine Specifications ■ Machine Specifications GENOS L250II C × 500 C × 290 ø450 (17.72) ø350 (13.78) ø300 (11.81) V8 turret: ø280 (11.02) [V12 turret: ø220 (8.66)] 290 (11.42) 500 (19.69) 160 (6.30) 330 (12.99) 520 (20.47) [V12: 470 (18.50)] 30 to 3,000 [high torque: 20 to 2,000, high speed: 45 to 4,500] Infinitely variable JIS A2-6 ø66 (2.60) ø100 (3.94) V8 [V12] 8 [12] 25 (0.98) ø40 (1.57) [V12: ø32 (1.26)] ø40 (1.57) [V12: ø32 (1.26)] ø32 (1.26) 0.3/index X: 25 (82), Z: 30 (98) ø90 (3.54) — ø70 (2.76) MT No. 5 (revolving center) — MT No. 4 (revolving center) 100 (3.94) — 80 (3.15) 11/7.5/7.5 (15/10/10) (10 min/30 min/cont) X: 3.0 (4), Z: 3.0 (4) 0.55/0.75 (0.7/1) 1,669 (65.71) Model name Item Spec extension Capacity Travels Spindle T Swing over bed mm (in) Swing over carriage mm (in) Swing over cross-slide mm (in) Max turning dia mm (in) Max work length mm (in) X axis mm (in) Z axis mm (in) min-1 Speed Speed ranges Nose Turret Bore dia mm (in) Front bearing dia mm (in) Type No. of tools OD tool shank mm (in) ID tool shank dia mm (in) sec Turret indexing time Feedrates Rapid traverse m/min (fpm) Tailstock Quill diameter mm (in) Tapered bore type Motors Quill travel mm (in) Main spindle kW (hp) Axis drive kW (hp) Coolant electric motor (50/60 Hz) kW (hp) mm (in) Height Machine size kg (lb) Machine weight 2,800 (6,160) T Spindle GENOS L250II C × 500 C × 290 A2-6, 30 to 3,000 min-1 11/7.5/7.5 (10 min/30 min/cont) — T MT No. 4 (revolving center) MT No. 5 (revolving center) Manual Manual tow-along Traveling system GENOS L400II C × 500 A2-8, 25 to 3,000 min-1 11/7.5 (30 min/cont) C × 1100 — MT No. 5 (revolving center) MT No. 4 (dead center**) mm (in) V8 turret: ø390 (15.35) [V12 turret: ø310 (12.20)] V8 turret: ø410 (16.14) [V12 turret: ø330 (12.99)] Max work length mm (in) 500 (19.69) 1,100 (43.31) X axis mm (in) 220 (8.66) 230 (9.06) Z axis mm (in) min-1 520 (20.47) 1,144 (45.04) Speed 25 to 3,000 [high torque: 13 to 2,000, high torque, high power: 17 to 2,000] 2 auto ranges (2 range motor coil switching) JIS A2-8 Bore dia mm (in) ø80 (3.15) Front bearing dia mm (in) ø120 (4.72) Type V8 [V12] 8 [12] OD tool shank mm (in) 25 (0.98) ID tool shank dia mm (in) ø40 (1.57) sec 0.3/index X: 25 (82), Z: 30 (98) Rapid traverse m/min (fpm) Tailstock Quill diameter mm (in) Tapered bore type Motors Machine size — ø90 (3.54) — Quill travel mm (in) Main spindle kW (hp) Axis drive kW (hp) MT No. 5 (revolving center) — Machine weight 11/7.5 (15/10) (30 min/cont) [high power motor: 15/11 (30 min/cont)] X: 2.8 (4), Z: 3.5 (5) X: 2.8 (4), Z: 4.6 (6) 0.55/0.75 (0.7/1) mm × mm (in) kg (lb) MT No. 4 (dead center*) 100 (3.94) Coolant electric motor (50/60 Hz) kW (hp) mm (in) Height Floor space: width × depth (including tank) 1,791 (70.51) 2,057 (80.98) 2,280 × 1,855 (89.76 × 73.03) 3,537 × 2,453 (139.25 × 96.57) 4,350 (9,570) 4,500 (9,900) Spindle speeds V12 turret Chucking Centers Solid / hollow chuck Chuck size 6 in 8 in 10 in 12 in Standard spindle A2-6 ● — ● ● — Standard spindle A2-8 ● ● ■ Chucking Kits B kit 8 / 10 / 12 in Name GENOS L250II GENOS L400II OD- I 2 2 — 5 OD- II Soft jaws, B — 3 ID-H40 (offset ID-32) Hard jaws — 1 DS No. 2 H40 (H32) 1 DS No. 3 H40 — 1 BS 16-H40 (32) 2 — * ( ) are for GENOS L250II C × 290 11 Tailstock Coolant Air blower (blast) Coolant Chip discharge Door auto open/close Automation specs Hinge type ● ● Scraper type (rear discharge only) For steel For castings General use ● ● ● Magnet scraper for sludge processing Easy for maintenance Blade scraper — Shape 2 — Tailstock quill auto advance/retract confirmation, tailstock thrust high/low switch Shower, spindle bore, high pressure Chuck, turret, spindle bore, tailstock center High/low pressure switch Pump: 0.8 / 0.5 kW (60/50 Hz) Detection (level), mist collector mount Sludge measures Pan (side, rear), bucket Conveyor (side, rear; hinged L, H) Front door, the upper door Work rest, bar feeder, parts catcher, workpiece discharge conveyor, loader (OGL) ● 4 BS 20-H40 (32) BS 25-H40 Application Features Soft jaws, A * 12-inch chuck cannot be selected with GENOS L250II. * 6-inch chuck cannot be selected with GENOS L400II.
