Outstanding dimensional stabilitywith long-run machining of large workpieces

Manageable Deformation—Accurately Controlled

Thermo-Friendly Concept

Elimination of waste with use of Thermo-Friendly Concept

In addition to maintaining high dimensional accuracy when room temperature changes, Okuma's Thermo-Friendly Concept provides high dimensional accuracy during machine startup and machining restart.

To stabilize thermal deformation, warming-up time is shortened and the burden of dimensional correction during machining restart is reduced.

A function for controlling deformation caused by table or workpiece thermal expansion during room temperature or coolant temperature changes has been

added to TAS-C environmental thermal deformation control, enabling stable dimensional accuracy to be obtained in a large machining area.

Evolved TAS-C environmental thermal deformation control:Stable dimensional accuracy in large machining area

The benefits: better dimensional accuracy from large workpieces requiring long cycle times, and reduced dimensional variation from repetitive workpiece mount positioning.

Dimensional changes of less than 8 µm over timein a wide machining range (Room temperature change: 8˚C)

Optimized Servo Control

SERVONAVI AI (Automatic Identification)

Achieves long term accuracy and surface quality

SERVONAVI SF (Surface Fine-tuning)

On table travel type machining centers, the table feed accelera-tion with the previous system was the same regardless of weight, such as workpieces and fixtures loaded on the table.

Work Weight Auto Setting estimates the weight of the workpiece and fixture on the table and automatically sets servo parameters, including acceleration, to the optimum values. Cycle times are shortened with no changes to machining accuracy.

■ Cycle time shortened with faster acceleration

Work Weight Auto SettingSlide resistance changes with length of time machine tools are utilized, and discrepancies occur with the servo parameters that were the best when the machine was first installed. This may produce crease marks at motion reversals and affect machining accuracy (part surface quality).

SERVONAVI’s Reversal Spike Auto Adjustment maintains machining accuracy by switching servo parameters to the optimum values matched to changes in slide resistance.

■ Maintains machining accuracy and surface quality

Reversal Spike Auto Adjustment

Comparison of DBB* measurements

When aging changes machine performance, noise, vibration, crease marks, or fish scales may appear. Vibration Auto Adjustment can quickly eliminate noise and vibration even from machines with years of operation.

Satisfaction from complete control of a machine tool

■ Setup operations

■ Trial/continuous cuts■ Programming ■ Tool preparations

As a “machine & control” builder, Okuma makes further strides in machine tool manufacturing with

this superb Control featuring “Easy Operation.” Okuma took a close look at the way machinists

actually operate machine tools, to help them create smoother and more effective ways of producing

parts. Novice operators as well as professional machinists get complete control—and satisfaction.

Moreover, what you want to see and do conveniently come together in a “single-mode operation.”

First, select one of three operation screens. Then simply touch the screen or press a function key to

see and do your job.

With spreadsheet simplicity —tool offsets, tilt, shape, life, etc—all the tool data required to cut a part can be registered here.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.

The touch sensor screen pops up from the tool registration screen. Tool compensation values are set while looking at a guidance message.

■ Adjust cutting conditions while monitoringthe data (M-g)

Based on the chatter noise captured by the microphone, Machining Navi displays a number of optimal spindle speed possibilities on the screen. The operator can change to the indicated spindle speed with a single touch and immediately confirm the result.

■ Automatically changes to optimum spindle speed (M-i )

■ World’s first “Collision-Free Machine”CAS prevents collisions in automatic or manual mode, providing risk-free protection for the machine and great confidence for the operator.

Collision Avoidance System (Optional)

entioned in the instruction m

to the prod

uct.

To protect your factory and equipment from fire and assure continued safe operation, observe the following fire 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 fires. Always observe the following safety measures to ensure safe operation when machining flammable materials or when performing dry machining.

Before machining any material designated by law as a flammable substance, e.g., plastic, rubber, wood, acquaint yourself with the special characteristics of the material in terms of fire 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 fire if any chip should ignite.

Dry machining is a fire hazard because workpieces, tools, and chips are not cooled. To ensure safe operation, do not place any flammable 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 nonflammable cutting fluid 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 fire. Periodically clean the coolant filter to maintain sufficient coolant discharge, and frequently verify that coolant is discharging normally. Take measures to control the outbreak of fire: Place a fire extinguisher near the machine, have an operator constantly monitor operation, and install an automatic fire extinguishing system. Do not place flammable 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 fire extinguishing system and other peripherals are needed for grinding operations, please let us know as soon as possible if you plan to perform such operations.
