Long life, high rigidity and high accuracy

The box guide way construction and heavy bed castings

enable the machine to withstand continuous heavy cutting

associated with production turning.

Maintaining accuracy over a long life is a hallmark of

Okuma design engineering.

Okuma machine tools by design, maintaine their value.


Simple operation and maintenance by sophisticated design

4-Axis CNC Lathes

High Speed Spindle, Fast Rapid

Traverse and Fast Turret Indexing

Rugged spindle of large diameter is supported

by double roller and angular bearing.

The rigit turret is indexed by gear drive

mechanism for the non-stop short-cut tool

selection.

Three-in-One Productivity and Efficiency

in Any Mode of Operation

Working as a team or individually, both spindles

increase turning efficiency in any of three different

modes of machining such as identical operations

for identical parts, different operations for

identical parts.

If automatic door is equipped on the machine as

optional accessory, each side can be separately

operated for easy and speedy turning jobs.

Ergonomic Design

Okuma 2SP Series are more efficient in

operation than using two single spindle

lathes simultaneously.

Twin spindle design saves space and movement

for the operator.

2SPH series lathes

Two machines

Spindle O.D. Ø100 Ø120

Easy Chip Disposal

The "straight down" chip disposal system

results in efficient disposal of chips and

coolant with no obstructions.

Chips will not build up on any surfaces

within the machine.

Machine thermal distortion is minimized

because chips are caught and disposed

by a chip conveyor assembly separate

from the bed casting.

Manual Work Loading and

Unloading Capability

There are no obstacles at the front of the

machine to obstruct the operator's access to

the chuck and turret.

The detachable partition provided between the

spindles assures safety of the operator if he is

working at one spindle while the other is working

for him. It can be moved for easy access to

either spindle.

1

DOUBLE part productivity

by machining the same

part on each of the two

spindles simultaneously.

2

STREAMLINE your production

process by using

one spindle for the first

process and the other

spindle for the second

process.

3

DIVERSIFY your production

system by using the

two spindles to turn two

entirely different parts.


Various Optional Accessories are Available for 2SP Series

Chip Coneyor (Option)

The chip conveyor is selectable to meet you

floor plan.









Automatically Operated

Splashguard(Option)

The splashguard is controlled by M-function

to ease operation.

Q.T.S Quick Tool Setter

(Option)

The tool offsets can be easily set by means

of the tool probe.

Simply bring the tool in contact with the

probe sensor and the gage length is automatically

determined and stored in the CNC

control.

Driven Tool System (Option)

Milling Function

Turning, drilling, tapping and various milling

can be done in a single chucking.
