Decarbonize your factories with Okuma
Since 1963, Okuma has been developing numerous energy-saving technologies, such as the self-designed numerical control, the Thermo-Friendly Concept, the ECO Suite, the cycle time reduction or the Sludgeless Tank. Accordingly, Okuma is contributing to decarbonisation in customers' production with various technologies and the high-precision machine tools.
Three leading points for Okuma's Green Smart Machines:
- Reduce energy during machining
- Stopping unnecessary equipment proactively
- Shortening cycle times
Machine tools not only consume energy during use, but also during set-up and standby times. Through unique concepts, Okuma has succeeded in significantly reducing these CO₂ emissions during production. The accuracy of the machines is not affected. Lower energy consumption and shorter cycle times also improve productivity and reduce CO₂ emissions.

Reduce energy during machining
THERMO-FRIENDLY CONCEPT
Use temperature changes instead of fighting them: High permanent accuracy without machine coolers or complex air conditioning systems.
POWER REGENERATION SYSTEM
Previously unused, now standard in energy recovery: the energy released during decelerations is used, so there is no longer any waste of energy.
Stopping unnecessary equipment
AUTOMATIC POWER SHUTDOWN: When machining stops during unmanned operation, the power is automatically cut after a preset time period.
ECO SUITE PLUS: The concept combines various systems for saving CO₂ emissions with an environmentally friendly approach.
ECO POWER MONITOR
With the OSP control, the operating status and CO₂ emissions can be recorded and analysed with pinpoint accuracy. The accompanying visualisation and integrated energy-saving functions support the energy reduction.
ECO IDLING STOP
Thanks to ECO Suite Plus, the machine automatically detects the operating status of all components of the machine and puts them into an energy-saving idling mode according to need.
ECO OPERATION
With the ECO Suite Plus, other peripheral devices can also be optionally adapted to the operation. Operation can be fine-tuned even more, as many CO₂ emissions as possible are reduced and energy consumption is lowered.
ECO HYDRAULICS
The highly efficient hydraulic unit significantly reduces power consumption. Example: With a conventional unit, the MB-4000H requires a power consumption of 840 W. With the optional ECO hydraulics, only 260 W are needed at 25 min-1.
Shortening cycle times
Cycle times and energy consumption are significantly reduced by selecting optimal parameter settings for the workpiece and matching machining operations with simple settings on the machine. Okuma's intelligent Technologies help to reduce cycle times, save CO2 emissions and maintain the highest possible production quality. Find out more about Okuma's Intelligent Technologies here.
SLUDGELESS TANK (optional)

- Reduced cleaning cycles
- Less production interruption
- Three different degrees of filtration (Drum, cyclone and bag filter)
Your benefits:
- Sludge removal: 99 % (casting)
- Cleaning of the coolant tank: Every 3 years (in-house)
- Change of coolant: Every 3 years (in-house)

3D CALIBRATION
Semi-automatic calibration is performed with a precision master and probe measurement. This reduces CO2 emissions during rework and disposal of defective products. The probe is moved over the optionally available precision master on the worktable. An auto gauging takes place, which results in an error calculation and automatic compensation of the parameters.
