Thermo-FriendlyConcept

Manageable Deformation--Accurately Controlled

Thermo-Friendly Concept

Eliminate waste with the 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.

Advanced TAS-C: dimensional accuracy stabilized over full table range

When machining a series of workpieces setup on the work table, dimensional accuracies will vary and prevent efficient production. TAS-C (Thermo Active Stabilizer––Construction) now includes a function to control table expansion, to provide stable dimensional accuracy no matter where a workpiece is mounted on the table.

[Spindle shaft cooling]

Spindle shaft cooling to minimize effects of heat on tools For 20,000-min-1, 30,000-min-1 spindles

Spindle and tool temperature rise is minimal, and thermal deformation

becomes smaller. In addition,the time required to reach stable thermal

deformation boundaries is reduced, thus warmup time can also be

shortened.

� Spindle thermal matrix

A “spindle thermal matrix” can be produced by a small-diameter endmill making slowly inclining linear grooves at 1-minute intervals on a horizontal surface. Spindle growth can be determined by the different groove lengths produced. While performing spindle speed changes and stop/start machining, a stable (adiabatic) deformation zone will be reached.

Spindle shaft cooling will suppress spindle temperature changes, reduce spindle growth, and thus shorten the time to reach thermostability.

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 Operate". 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.

For fast and accurate die/mold applications

� Super-NURBS high speed contouringHigh speed NC function for high accuracy, high quality, and high

speed machining of curved surfaces of any shape, with newly-developed “sculptured-surface adaptive acceleration control.”

� Projection Flatten Control II (PFC II) By dynamically compensating for lost motion, backlash, and other

movements during reverse axial travel, protrusions during arc quadrant switching movement can be inhibited.

� Feed axis bending compensationBending is a cause of expansion/ contraction and torsion of the

drive system that is produced during acceleration and deceleration. By compensating for bending, unevenness from reciprocating movement can be minimized. This is particularly effective in die/mold machining.

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.
