**What is a Mobile/Tank Circulation Fine Bubble Generation Device?** It circulates the clean liquid in the coolant tank used in machine tools through a fine bubble generation device. This process fine-bubbles the clean liquid, creating various benefits! It generates ultra-fine bubbles ranging from micro to nano size that carry a negative charge, adsorbing and removing dirt and oil, thus cleaning and preventing clogging of grinding wheels, while also suppressing the decay and deterioration of the coolant liquid. **Voices from Users Who Have Introduced the Device** The clogging of grinding wheels has been extended compared to before, leading to longer dressing intervals and improved productivity. By combining it with precision filtration, even after four years of introducing a new centerless grinding machine, dirt inside the machine is not noticeable. This has improved the machine's lifespan. One week after introducing fine bubbles, dirt in the machine's piping flowed into the tank, but since then, unpleasant odors in the tank have been eliminated. The cleaning efficiency and sterilization effect have become apparent. Thanks to the oil-water separation effect, lubricating oil that was trapped in the tank could be floated to the surface, allowing for efficient recovery.
