Why Okuma is
chosenOkuma, a manufacturer of 5-axis machining centers and multitasking machines
We have received the following responses from customers
Machining accuracy is as stable as that of lathes and machining centers
The cutting capability is equal
to that of lathes and
machining centers
There is no need to worry about collisions during machining, providing a sense of security
5-axis machining centers and multitasking machinesmaximize productivity in machining shops
Why they are chosen!
Stable high precision
The ability to maintain a consistently high level of precision is a hallmark feature of the Okuma brand
- The same level of precision as that of Okuma’s lathes and machining centers is ensured
- Accuracy variations that are caused from setup changes between processes do not occur with process-intensive machining.
- Power consumption can be reduced without compromising precision or productivity
Machining precision is as stable as that of lathes and machining centers

Okuma’s innovative technology enables high-precision machining
-
Thermo-Friendly
Concept -
Reduces precision defects caused by thermal deformation
Machining precision of the workpiece changes significantly due to ambient temperatures around the machine, heat generated by the machine, and heat generated during machining. The Thermo-Friendly Concept is the unique concept of “accepting” these temperature changes so that high precision can be achieved in normal factory environments with no special measures by the user.

5-Axis Auto Tuning System
-
Measures and compensates errors in axis position and tilt
On 5-axis machines there are “geometric errors” such as spindle misalignment, that have huge effects on machining accuracy. The 5-Axis Auto Tuning System measures geometric errors with a touch probe and datum sphere, and tunes 5-axis machines for better operating accuracy through compensation control using the measurement results. This helps to achieve a higher level of 5-axis machining accuracy.
Machining capability
High machining capability equivalent to those of lathes and machining centers supports a wide range of operations, from heavy-duty cutting to machining difficult-to-cut materials

Machining Navi
-
Navigate to the best cutting conditions
With graphical representation of machine performance, the operator can easily select optimal cutting conditions.
-
SERVONAVI
-
High accuracy, stable machining maintained for long periods
The changes that occur with use over long years from workpiece weight and inertial mass are automatically recognized, and the feed axis and spindle control parameters are optimized.
- Dynamic Tool Load Control
-
DTLC suppresses chipping of insert tools on difficult-to-cut materials like titanium alloy, to achieve stable processing and longer tool life.
Ease of use
Okuma's 5-axis machining centers and multitasking machines maximize machine uptime
- "Collision-Free Machines" ensure operator confidence and safety
- Abnormalities in the spindle and feed axis can be detected and identified quickly to minimize downtime
- Chip disposal and tank cleaning frequency is reduced
Okuma's innovative technology delivers exceptional ease of use
-
Collision Avoidance System
-
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.
- AI Machine Diagnosis Function
-
Okuma’s AI-equipped CNC control diagnoses for abnormalities in the machine spindle and feed axes and identifies any irregularities found. This minimizes downtime caused by machine shutdown and enables stable productivity to be maintained over long periods of time.
- Sludgeless Tank
-
- No tank cleaning for 3 years
- No coolant replacement for
3 years - Sludge removal rate 99%
Sludge buildup in the coolant tank is effectively minimized
The need for troublesome tank cleaning is significantly reducedEfficient sludge collection eliminates strain on workers and operational losses caused by sludge. This significantly reduces the need for frequent tank cleaning, ensuring stable and long operations.
