2-Spindle Horizontal CNC lathes

2SP series machines are true 2-spindle lathes

that boast space savings and high productivity

(The photo includes optional speci cations.)With the 2SP-35H/HG, OSP and FANUC speci cations can be selected. (The photo shows OSP speci cations.)

The G in the machine name stands for the gantry loader. The 2SP-10HG has FANUC specifications only.

● 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

Wide array of results to achieve high utilization

High speed and stable cut

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. A simple push of the button helps reduce

operator fatigue.

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)

● 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 positioned 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.

NC gantry loaders for laborsaving automationWide array 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.
