We would like to introduce a case where we developed a dedicated non-water-soluble cutting oil at the request of a company in Niigata Prefecture, which led to improvements in the working environment. This company was using a non-water-soluble cutting oil classified as a Class 4 hazardous material, Category 3 petroleum product. However, due to its quantity being close to the specified limit under the Fire Service Act, they were considering switching to Class 4 petroleum products. Although it took some time, we developed a dedicated oil that maintained low viscosity, which reduced the amount of mist generated. Consequently, the mist that floated in the factory during operations such as opening and closing machine windows also decreased. [Case Overview] ■ Issues - The non-water-soluble cutting oil classified as a Class 3 petroleum product was close to the specified limit under the Fire Service Act, prompting consideration of Class 4 petroleum products. ■ Implementation Effects - We developed a dedicated oil for Class 4 petroleum products, successfully improving the working environment by reducing the amount of mist generated. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where the change to a non-water-soluble cutting oil significantly reduced oil mist, based on a consultation from a customer using oil-based cutting oil in a machining center. The generation of a large amount of mist was pointed out as deteriorating the working environment, and the oil mist generated during processing made the workers' hair and clothes sticky and gave off an oily smell. When we proposed a paraffin-rich oil-based cutting oil, the oil mist visibly decreased, and the adhesion and stickiness to the workers' hair and clothes were significantly reduced. [Case Summary] ■ Issues - A large amount of oil mist was generated, deteriorating the working environment. ■ Implementation Effects - Visible reduction in oil mist. - Significant decrease in adhesion and stickiness to workers' hair and clothes. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case study where the introduction of low-mist water-soluble cutting oil improved the working environment and reduced the amount of cutting oil used. In a machining center using water-soluble cutting oil, operators reported that "the smell when opening the processing room door due to mist sometimes makes them feel unwell." After the introduction, we received feedback that "the mist has decreased and the smell is less than before," leading to less oil contamination on work clothes and around machines, which contributed to an improved working environment. [Case Overview] ■ Issues - Employees raised concerns about unpleasant odors caused by oil mist. ■ Effects of Implementation - Reduction of unpleasant odors and oil contamination due to decreased oil mist. - Led to a reduction in coolant usage. *For more details, please download the PDF or feel free to contact us.

After the implementation, the surface accuracy improved, tool life extended by approximately 1.3 times, and the frequency of cutting oil replenishment reduced from four times a week to just twice, contributing to increased production efficiency in many aspects. [Case Summary] ■ Challenges - Inconsistent surface accuracy in turning processes resulted in variations in product finish. ■ Implementation Effects - Significant improvement in surface accuracy, extension of tool life, reduction in usage, and improvement in skin irritation. *For more details, please download the PDF or feel free to contact us.

Here is a case study on eliminating rust on products that occurs after processing with water-soluble cutting oil. The background for this introduction is that after rust prevention treatment, rust appeared on several products, leading to an increase in the amount of rust prevention oil used and resulting in higher costs. By being able to remove the components of the water-soluble cutting oil down to minimal residues, the performance of the rust prevention oil began to act on the metal surface, resolving the rust issue. 【Case Summary】 ■Challenges - Rust on products, increased usage of rust prevention oil ■Benefits - Elimination of rust, annual cost reduction of 500,000 yen *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case that contributed to suppressing the discoloration of water-soluble cutting oil, improving production efficiency and enhancing the working environment. Previously, while processing cast parts with machining centers and NC lathes, the water-soluble cutting oil used would become brown and dirty within about 2 to 3 months after replacement. After the improvement, the cutting oil no longer became brown and dirty, allowing it to be used for 2 years without replacement, and there was no need to wash it with a parts cleaner. [Case Overview] ■ Issues - Water-soluble cutting oil becomes brown and dirty within about 2 to 3 months after replacement. - Cleaning products and fully replacing cutting oil is labor-intensive. ■ Benefits of Implementation - The frequency of cutting oil replacement was extended from 3 months to 2 years. - There was no longer a need to use parts cleaner for product cleaning. *For more details, please download the PDF or feel free to contact us.

We received a request from a company in Niigata Prefecture to introduce a case where we prevented foaming of water-soluble cutting oil and reduced coolant usage by 15%. Upon inspecting the machine, we found that the filter inside the tank was clogged, which can cause foaming issues with the water-soluble cutting oil. We proposed a low-viscosity oil that would reduce the clogging of the filter. After implementation, we thoroughly cleaned the tank, including the filter, along with the coolant replacement work. As a result, the filter became less prone to clogging, and the overflow caused by foaming was eliminated. [Challenges Before Implementation] ■ Frequent occurrences of foaming of water-soluble cutting oil during processing, leading to leaks from the tank. ■ Operators had to stop the machine to clean around the tank and replenish the coolant, which resulted in significant time and cost for refilling, as well as excessive machine downtime, negatively impacting production efficiency. ■ Foaming increased the risk of reduced processing capability due to insufficient supply of cutting oil, leading to potential defects in parts, causing significant concern. *For more details, please download the PDF or feel free to contact us.*

We would like to introduce a case where we implemented a water-soluble cutting oil with excellent defoaming properties to address high-pressure coolant requirements. The customer in this case faced the challenge of coolant easily foaming due to the machine structure, leading to cutting oil overflowing from the tank. After implementation, the defoaming effect lasted for about a month, so the customer decided to assign a duty to ensure that an additive was added at least once a month during the winter period, even when there was no foam. As a result, the foam from the cleaning agent no longer overflowed from the tank. 【Case Overview】 ■ Challenges Before Implementation - The machine structure caused coolant to easily foam, resulting in cutting oil overflowing from the tank. ■ Reason for Selection - Since there was a request not to change the cleaning agent, we proposed a compatible "non-silicone additive" suitable for the current product type. *For more details, please download the PDF or feel free to contact us.

We received a request from a foundry processing company in Nagano Prefecture regarding the issue of water-soluble cutting oil deteriorating within six months, leading to a worsening work environment and frequent rust problems with the products. We proposed using a "micro-emulsion" type cutting oil developed for foundry processing to address the customer's challenges. Additionally, we decided to implement regular concentration management of the cutting oil and conduct usage liquid analysis every three months. By selecting the appropriate oil based on the processing requirements and providing support for oil management, we achieved a result where the water-soluble cutting oil, which previously deteriorated within six months of replacement, remained intact without any deterioration even after five years. [Challenges Before Implementation] - Various types of water-soluble cutting oils had been used traditionally, but all deteriorated within six months, resulting in a constant foul odor in the workplace. - The machines had to be stopped twice a year, incurring significant costs for extensive cutting oil replacement work. - The deterioration of the cutting oil led to a decline in performance, causing rust to form on the processed products. *For more details, please download the PDF or feel free to contact us.*

We received feedback from a company in Niigata Prefecture expressing a desire to test an oil agent that is considerate of hands, has a long liquid lifespan, and is less sticky. In response, we proposed an oil agent from the soluble type that is gentle on the skin and has good oil separation properties. While conventional oil agents would spoil in about three months, our product has shown no issues even after more than six months, successfully reducing waste liquid disposal costs by approximately 40,000 yen per machine annually due to the extended liquid lifespan. Additionally, by providing on-site support to enhance operators' awareness of oil agent management and conducting regular liquid analysis for quantitative management, we expect the liquid replacement cycle to be further extended. [Background of Introduction] - The previously used water-soluble cutting oil spoiled and produced an unpleasant odor. - Complaints were received from workers. - Due to past issues with hand irritation, there was a desire to test an oil agent that is considerate of hands and has a long liquid lifespan with less stickiness. *For more details, please download the PDF or feel free to contact us.*

We would like to introduce a case study conducted by a company in Nagano Prefecture that specializes in machining industrial machinery and automotive parts. The frequency of changing the cutting oil for the five-sided machining center was once every six months, but in reality, after about two to three months, an odor began to gradually permeate the air, and by the six-month mark, the factory was filled with this odor. We proposed adding a special surfactant during the oil change to thoroughly remove not only the residual oil in the tank but also the dirt and bacteria remaining in the piping before filling it with new fluid. This resulted in extending the lifespan of the cutting oil from six months to over a year. [Background of Implementation] - The company had been using a milky white type of water-soluble cutting oil for many years, and the oil was replaced only when it began to spoil or when workers started to notice the odor. - Although the cutting oil was changed every six months, in reality, an odor would start to develop after two to three months, and by the six-month mark, the factory was filled with this odor. - The costs associated with coolant waste disposal and labor for the replacement work were also problematic from a cost perspective. *For more details, please download the PDF or feel free to contact us.*

We would like to introduce a case we received from a company engaged in metal cutting, drilling, and sheet metal processing. This company had been using a translucent type of water-soluble cutting oil and performed coolant replacement approximately twice a year. However, within two weeks, the translucent liquid became cloudy, and at the same time, it developed stickiness, mold, and odor. We proposed the use of a water-soluble cutting oil that is less prone to emulsifying with other oils and has excellent cleaning properties. After its introduction, by removing the sliding surface oil, the condition of the liquid was maintained, preventing the occurrence of mold and odor. [Challenges Before Introduction] ■ Although coolant replacement was performed twice a year, the condition of the liquid deteriorated quickly, leading to the development of mold and odor. ■ Even after the coolant replacement, it was necessary to replace the coolant again after six months. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case that was consulted by a company engaged in mechanical design and manufacturing, as well as machining of mechanical parts. In the customer's environment, there were issues with the odor and separation of water-soluble cutting oil during the summer, as well as the residue of sliding surface oil. Given the structure of the machinery, this situation was somewhat accepted as a matter of course. We suggested trying a dedicated lubricant for sliding surfaces that is less likely to mix with cutting oil. After its implementation, the separation of sliding surface oil improved, leading to an increased recovery rate of the oil skimmer, which resulted in reduced odors and eliminated stickiness. [Challenges Before Implementation] ■ Especially during the summer, odors and separation were likely to occur with water-soluble cutting oil, necessitating regular replacement work. ■ Sliding surface oil was easily emulsified by cutting oil, and due to the relatively large coolant tank of 800L, sliding surface oil could not be fully recovered. ■ Given the structure of the machinery, this situation was somewhat accepted as a matter of course. *For more details, please download the PDF or feel free to contact us.

We received an inquiry from a customer using oil-based cutting oil in a machining center, and we would like to introduce a case where we proposed a paraffin-rich oil-based cutting oil. Before the introduction, there was a challenge of excessive oil mist generation, which worsened the working environment. After the introduction, the oil mist visibly decreased, significantly reducing the adherence of oil to the workers' hair and clothing, as well as the stickiness. 【Challenges Before Introduction】 ■ Workers' hair and clothing became sticky and smelled of oil. ■ The area around the machines became sticky, dirtying the ceiling and worsening the working environment. ■ When blowing off chips after processing, it was difficult to remove them, which occasionally caused scratches on the workpieces and resulted in defects. *For more details, please download the PDF or feel free to contact us.

We would like to introduce a case where a low-mist water-soluble cutting oil was implemented at a site using water-soluble cutting oil in a machining center, resulting in improved working conditions and reduced usage of cutting oil. Before the implementation, employees had raised concerns about unpleasant odors caused by oil mist, but many had resigned themselves to the situation, believing that "it can't be helped as long as we are using cutting oil." We proposed switching to a low-mist water-soluble cutting oil, and after implementation, there was a reduction in unpleasant odors and oil stains due to decreased oil mist, as well as a reduction in coolant usage. [Case Overview] ■ Challenges before implementation - Employees raised concerns about unpleasant odors caused by oil mist. ■ Effects after implementation - Reduction of unpleasant odors and oil stains due to decreased oil mist. - Led to a reduction in coolant usage. *For more details, please download the PDF or feel free to contact us.
