[Improvement Case] By implementing ideas during the exchange, the lifespan of cutting oil increased from 6 months to over 1 year.

We will introduce a case where the work time per machine, which used to take 2 hours, has been reduced to 1 hour!

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.*
