2-Spindle Horizontal CNC lathes
(The photographed machine is equipped with optional specifications.)With the 2SP-35H/HG, OSP or FANUC specifications can be selected. (The photo shows OSP specifications.)
� Max turning diameter × length: ø100 × 100 mm
� Spindle motor: 7.5/5.5 kW
� Spindle speed: 50 to 5,000 min-1
� Turret type: V8 + V8
� Max turning diameter × length: ø380 × 230 mm
� Spindle motor: 18.5/15 kW
� Spindle speed: 20 to 2,000 min-1
� Turret type: V12 + V12
Okuma's compact 2SP Series lathes with innovative
front-facing dual spindles create automation-friendly
advantages for efficient small parts production.
The G in the machine name stands for the gantry loader. The 2SP-10HG has FANUC specifications only.

With vast experience in achieving high utilization rates
Fast and stable cutting operations
Operator home position
� Operator movement is reduced one-third with one 2SP-H compared to simultaneous use of two general-purpose single spindle NC lathes.
Structural design features“straight down chip drop”
� With the bed directly below a ram-type turret, straight down chip drop results in much shorter chip handling time and steady, long runs. And chips will not build up on any surface within the machine.
� Machine thermal deformation is minimized because chips are caught and discharged by a chip conveyor assembly separate from the bed casting.
Available in 3 different discharge directions to fit your shop layout requirements.
This easy-to-use manual Touch Setter really reduces setup times. Making a tool contact the sensor automatically stores an offset in the control system—quickly and accurately.
� Chip conveyors (Optional) � Auto front door open/close (Optional)
� Touch Setter (Optional) (2SP-35HG)
Wide array of variations significantly shorten setup time
� 2SP–H series lathes
� Two machines
Boring/drilling and slot machining can be done radially and axially in the workpiece with milling tool attached. Higher production effi-ciency achieved with process-intensive machining.
� Equipped with a central detachable partition between the two spindles to ensure safety when the two spindles are operating independently.
� When one side is operating automatically, setup can be done on the other spindle.
� Adapts flexibly to all kinds of production.
� Workpiece mount/dismount can be done with operator standing in front.
� Since there are no interfering structures in the machine front, there is excellent accessibility to the chuck and turret.
� The turrets are designed for easy tool edge checks and rigid, quick-change tooling packages.
Simultaneous parallel turning in the same operation
Continuous primary � secondary operations
Simultaneous turning of different workpieces
� The turrets, with fast indexing, drastically reduce non-cutting time.
Turret indexing: 0.2 sec (2SP-10HG)� With box ways for highly accurate and stable turning.
Twin spindles can also operate completely independent of each other
Easily accessible front facing chucks and turrets

NC gantry loaders for laborsaving automationFull line of variations to handle all types of production
Gantry loaders—for more productivity and flexibility (Optional)
� Conversational data input for loader movements—a safe, simple, and quick way to set up.
� AC servo drives for all 3 axes enable multiple workpiece and setup changes—quick and easy.
� If trouble occurs, recover methods are displayed on the screen to help the operator respond—quickly.
� A selection of loader movement patterns are available to match various production requirements. This flexibllity helps you make the production line changes that are needed—when you need them.
