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.

“All changes have one goal:
to provide our customers with consistently accurate machining while using less energy.
Thinking bigger, all companies need to step up their efforts to achieve society's carbon-neutral goals by 2050.”

THREE LEADING POINTS FOR OKUMA'S GREEN TECHNOLOGY

1.   Reduce energy during machining
2.   Stopping unnecessary equipment proactively
3.   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.

1. 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.

ECO-HYDRAULICS
The highly efficient hydraulic power pack reduces the power consumption of the entire machine. The improved servo control technology ensures precise control - even at ultra-low speed. In addition, noise, vibrations and also oil temperatures are reduced by the interaction of the highly efficient hydraulic pump, servo motor and pressure sensor.

2. 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
Energy savings and consistently high machining accuracy: these are the characteristics of the "Eco Suite Plus". The concept combines various systems for saving CO₂ emissions with an environmentally friendly approach.

ECO POWER MONITOR
With the OSP control developed by Okuma, 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
A large part of the energy consumption is accounted by all the additional devices of a machine tool. 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, such as chip conveyors or extraction, 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. In reality, this means: With a conventional hydraulic 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.

3. 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.

Even more savings potential

SLUDGELESS TANK (optional)

The goal of every production: to extend uninterrupted production cycles. The optional Sludgeless Tank makes a significant contribution to this. All particles that are flushed into the tank from the machining process are taken care of by the Sludgeless Tank. The cleaning cycles of the tank are reduced and production is interrupted less. The process initially consists of a permanent flow of the coolant with all impurities so that they cannot settle in the tank and are flushed directly to the filter stages with different degrees of filtration. The primary filtration takes place in a drum filter for lift-up chip conveyor. Secondary filtration is then carried out with a cyclone filter. Last but not least, the tertiary filtration is done with a bag filter.

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 C02 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.
