We will introduce a case study of a precision coolant filtration system. Just because the frequency of filter replacements has increased, it does not necessarily mean there is a problem with the filter itself. What is important is to check the amount of sludge, the nature of the sludge, and the condition of the coolant liquid. Our company not only advises on appropriate filtration methods tailored to the customer's processing environment but also offers a "simple filtration test" that reports on improvement effects. If the amount of sludge is a priority, we also suggest a review of the overall filtration control, such as installing a centrifuge before the filter. [Challenges] ■ The frequency of filter replacements is increasing ■ The compatibility between sludge and filter is not suitable ■ The condition of the coolant liquid is changing *For more details, please refer to the related links or feel free to contact us.

Reducing waste disposal costs by 1/10! Here we introduce a case study of a precision coolant filtration system that was implemented. Traditionally, the site faced the hassle of liquid replacement, high frequency of grinding wheel dressing, and increasing tool costs, along with the burden of significant waste disposal expenses. To address this, we introduced a system equipped with a unique "automatic backwashing function." By utilizing air pressure waves and filtered liquid, we automatically resolve clogging on the filter surface, extending the filter's lifespan and reducing the frequency of replacements. [Challenges] ■ Keeping waste disposal costs to 1/10 ■ Halving the frequency of grinding wheel dressing to save on tool costs ■ Reducing the hassle of liquid replacement to lighten the burden on the site *For more details, please refer to the related links or feel free to contact us.

Are you troubled by scratches on the workpiece and abnormal wear of grinding wheels in the grinding and cutting of "brittle materials" such as quartz glass, ceramics, and cemented carbide? The cause lies in the "invisible fine sludge" of less than 10μm that slips through common magnetic separators and cyclone filters. In this article, we will explain the mechanisms of the serious troubles caused by these fine particles and introduce the concept of "precision filtration management" to maintain a clean state while preventing filter clogging. Rather than relying solely on field experience, visualizing sludge in numerical terms and selecting the optimal system will be key to ensuring stable processing over the long term and protecting brand value. *For more detailed information, please refer to the related links.

**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.
