We would like to introduce a case from a company in Niigata Prefecture that uses water-soluble cutting oil in their machining process. Due to contamination from oil, the coolant deteriorated in about a year, and the degradation of the oil caused a decline in the working environment, prompting a request for improvement. Upon inspecting the equipment, we found that the cause of the decay and stickiness was the existing belt-type oil skimmer, which was too dirty to recover the lubricant effectively. We proposed the introduction of a floating oil recovery device that uses a special filter for higher recovery rates. With the introduction of the floating oil recovery device, the coolant was cleaned in a short time, and the frequency of coolant replacement was extended from once a year to once every two years. 【Background of Introduction】 - Contamination from other oils from the equipment was unavoidable, and while the existing oil skimmer was in use, recovery was not satisfactory, leading to coolant deterioration in about a year due to the contamination. - The factory became smelly due to the decay of the oil, and with a predominantly female workforce, there were many complaints, making the improvement of the working environment urgent. *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.*

• Cutting Oil

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.

• Cutting Oil

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.

• Cutting Oil

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.
