Okuma proposes the best automation systems for customers’ machining needs, including all peripheral devices, from work tables to gauges. The highest productivity with stable quality is achieved through all-out pursuit of speed, cost, and quality in mass-production parts machining.

1-machine 1-loader applications to full-scale production lines

The Thermo-Friendly Concept plays a principal role in our

machine design. With simple machine designs and construction

that equalize ambient temperatures, deformation is predictable,

and complex torsion or tilting is controlled.

Moreover, Highly Accurate Compensation Technology (Okuma

control [OSP] award winning innovation) effectively responds to

deformation caused by changes in room temperature, frequent

spindle speed changes, and non-coolant cutting.

With the Thermo-Friendly Concept (Manageable Deformation-

Accurately Controlled), Okuma products provide unrivaled

dimensional stability.

Diverse machining range with simultaneous 4-axis machining

Effective use of simultaneous 4-axis control enables machining suited to the user’s workpiece.

cycle times, operation mix, work

flow, floor space and the like.

● Selection of work tables, part

Compensation due to ambient temperature changes and temporary midday or evening machine stops is performed fewer times thanks to outstanding dimensional stability. This leads to better machine utilization, improving ef�ciency especially for mass-production machining.

Accurate control in a wide range of usage situations, including

use of coolant and travel stop during noon break.

● Ambient temperature change: 8 ˚C● Cutting conditions: Cold start, coolant used● Operating conditions: Spindle speed 3,200 min-1, 24 hr● Material: BsB

■ Fewer tool compensation checks ■ Minimizes dimensional changes from thermal deformation■ OD turning including continuous cutting

Cycle time: 1 min 28 sec

● Infeed: 4 mm

● Feed: 0.5 mm/rev

Powerful turning

Roller guides are used on all axes for ready handling of

continuous cutting, which places a large burden on the

machine. Rugged structure from placement of multiple

ribs within the bed gives substantial construction while

maintaining a compact size.

Tough structure stands up easily to continuous cutting

60° slant bed construction ensures superior visibility of

the tool edge and machining status, as well a working

chamber sufficient for loader handling. Operator burden

is also decreased with workability considerations

including workpiece loading/unloading position and tool

change position for working ease.

Machine configuration for outstanding workability

Mounting the spindle motor outside the bed minimizes

the effect of thermal deformation on machining

accuracy. Outside motor placement also makes

maintenance work easier.

The LU-S1600 handles shafts from ø60 mm up to ø160 mm. The LU-S1600 is also compatible

with boring bars up to ø32 mm, for powerful machining of inner diameters of CVJ outer rings and

other workpieces. Various other machining processes are also possible, including balanced

simultaneous 4-axis cuts on upper and lower turrets, inner and outer diameters.

Broad range of workpieces, wide variety of operations

● Turret indexing time:

0.15 sec per station

(both upper and lower)

Fast turret movement

Stable machining of long workpieces with

highly rigid tailstock that uses a MT No. 5

revolving center.

Achieves stable machining

XB double wipers are used on the lower

turret where chips accumulate, while a

chip flusher is used on the saddle top.

Chip discharge is greatly improved by

using a single stainlessteel sheet for the

guideway cover on the spindle side and

other modifications, for continuous

mass-production machining without stops.

The best possible chip removal based on

our solid record of 2-saddle turning center

deliveries.

Chatter in a lathe can be suppressed by changing spindle speeds to the ideal amplitude and wave cycle.

Machining Navi shows its maximum effect in mass-production machining.The following example is a shaft workpiece that is very susceptible to chatter. With the use of Machining Navi four operations are reduced to two, producing many positive effects in mass-production machining.

OSP-P300L Okuma Sampling Path Control

Easy Operation

Okuma Control <for Lathes>

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)

Templates like this make it easy to set required jaw shape, tool, and cutting conditions.

Part programming not required to do this.

Operation screen split into four displays

Forming soft jaws Zero offsets

Simultaneous display includes setup work, current position needed in con�rming movement in trial machining, NC program, and graphic simulation.

Tool registration

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 select it from among the registered tools.ATC manual operation does not require inputting the tool number. Just select the tool from the list and press the function key.

To protect your factory and equipment from �re and assure continued safe operation, observe the following �re safety precautions whenever you operate machinery. Whenever possible, avoid the use of oil-based coolants for cutting operations. Sparks caused by hot chips, tool friction, and grinding can cause �res. Always observe the following safety measures to ensure safe operation when machining �ammable materials or when performing dry machining.

Before machining any material designated by law as a �ammable substance, e.g., plastic, rubber, wood, acquaint yourself with the special characteristics of the material in terms of �re prevention, and observe the precautions given in (2) above to ensure safe operation. Example: When machining magnesium, there is a danger that magnesium chips and water- soluble coolants will react to produce hydrogen gas, resulting in an explosive �re if any chip should ignite.

Dry machining is a �re hazard because workpieces, tools, and chips are not cooled. To ensure safe operation, do not place any �ammable objects near the machine and do not allow chips to over accumulate. In addition, be sure to check cutting tools to make sure of their service life and the condition of the tool edge, and observe the precautions regarding oil-based coolants given in (2) above.

(1) Use non�ammable cutting �uid coolant. (2) When the use of an oil-based coolant is unavoidable:

Before you begin machining, check cutting tools to make sure of their service life and the condition of the tool edge, and choose cutting conditions that will not cause a �re. Periodically clean the coolant �lter to maintain suf�cient coolant discharge, and frequently verify that coolant is discharging normally. Take measures to control the outbreak of �re: Place a �re extinguisher near the machine, have an operator constantly monitor operation, and install an automatic �re extinguishing system. Do not place �ammable materials near the machine.Do not allow chips to over accumulate. Periodically clean the inside of the machine and the area surrounding it.Check that the machine is operating normally. Never run the machine unattended. Since an automatic �re extinguishing system and other peripherals are needed, please let us know as soon as possible if you plan to perform such operations.

Fire Safety Precautions

1. Oil-based coolant

2. Precautions regarding machining of potentially �ammable materials

3. Dry machining
