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.
Introduction merit
High dimensional stability
Machining restart
Room temp change

Superior chip discharge
● VAC motor (spindle) and brushless servo motors(servo axes)
require no brush changing
● NC Torqur Limiter on servos minimizes any damage from
possible operator error and makes it easy to resume
processing.
● All ordinary miantenance from machine front: chuck pressure
adjustment, tailstock pressure adjustment, way lubrication etc.
Maintenance couldn’t be easier
● Smooth chip discharge
· Large outlet directly beneath chuck
· Saddle cover with good chip flow
● Sealed cover construction including tailstock guideway
● Improved workplace environment with sophisticated
appearance and covering with no water leakage

Thermo-FriendlyConcept
Manageable Deformation—Accurately Controlled
Thermo-Friendly Concept
The unique approach of "accepting temperature "changes."
Okuma’s Thermo-Friendly is a structurally designed, thermal deformation control system that provides astonishing machining accuracy.
It frees the machinist from troublesome offsets and machine warm-ups—is superb for long runs, multitasking, front/backend work, plus Y-axis
applications.

Environmental economic benefits of Okuma’s Thermo-Friendly Concept
Super thermostability minimizes machining dimensional changes over time
In environments with normal temperature changes, machining accuracies equivalent to those in temperature-controlled rooms are achieved.As long as the operator is comfortable, no air conditioning is needed to ensure accuracy.
Prevents CO2 emissions equivalent to about 11,500 beechtrees
■ Amount of energy consumed fortemperature-controlled room

■ Trial/continuous cuts
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.

■ World’s first “Collision-Free Machine” ■ Chatter-free applications for lathes
Virtual machine (collision check)
CAS prevents collisions in automatic or manual mode, providing risk-free protection for the machine and great confidence for the operator.
Chatter in a lathe can be suppressed by changing spindle speeds to the ideal amplitude and wave cycle—without decreasing spindle speed.

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.
