A fine bubble generator specialized in producing ultra-fine bubbles.
It is effective for cooling machining equipment and addressing issues such as ultrasonic cleaning in semiconductor processing, microcracks, and chipping.
Water containing fine bubbles has lower surface tension due to surfactant-like effects, allowing bubbles to penetrate tiny gaps more easily.
Experiments, such as dropping water and fine bubble water onto sand, show that fine bubble water is absorbed more efficiently.
Improved Cooling
Improved penetration allows coolant to reach the heat source more effectively, enhancing cooling performance.
A thermal camera shows how machining heat during surface grinding is reduced by Functional Bubble Water and a flow-straightening nozzle.

When water was run through heated pipes, using fine-bubble water improved cooling performance by up to 20% compared to regular water. The nano-sized bubbles enhanced heat transfer efficiency.
Extend Tool Life &
Boost Efficiency
Coolant with strong wetting keeps the blade protected from heat, reduces wear, and helps maintain sharpness for precise finishes.
Damaged cutting edge
No damage to cutting edge
Increased Productivity Through Reduced Machine Time
With sufficient cooling performance, machines can operate at higher power levels, enabling faster processing and shorter cycle times.
In addition, reduced tool wear extends continuous machine operation, increasing overall working speed and productivity.
Surface Grinding Example
Installing the SIO allows for up to 5x the normal cutting depth!
*Based on a 10μm reference depth
Drilling Example on a Machining Center
By installing SIO, it became possible to achieve machining conditions twice as high as normal, while the load value only showed a slight increase.
Measurement device: FANUC Servo Viewer
Ultrafine bubbles can penetrate tight spaces and slip beneath dirt layers, loosening them for easy removal.
As they capture contaminants, the bubbles gradually grow into microbubbles, lifting dirt to the surface.
Improved Cleaning
[Test Method] Ultrasonic cleaning of acrylic plates coated with melted beef tallow
[Equipment] Small benchtop ultrasonic cleaner
[Ultrasound Frequency] 40 kHz
Ultrafine bubbles are extremely small bubbles (less than 1 μm in diameter) that tend to remain in water for a long time. This allows them to be evenly distributed throughout the cleaning solution, effectively cleaning fine gaps and complex-shaped parts. Additionally, they enhance the cavitation effect (the shock effect caused by the rapid generation and collapse of bubbles due to sudden pressure drops in the liquid) in ultrasonic cleaning.
Fine bubbles, due to their tiny size,
are effectively utilized in ultrasonic cleaning applications.
