Abstract
This study analyzes the ineffectiveness of ultrasonic treatment for used cutting fluid sterilization. The microorganism population in a water-soluble cutting fluid sample was observed while applying a 40-㎑ ultrasound with a power density level of 0.27 and 0.37 W/㎠, respectively. The ultrasonic treatment was accompanied by a temperature rise due to the heating effect of cavitation or ultrasonic components. It was observed that the population does not vary below ~45℃, and drops rapidly as the temperature rises. This phenomenon is further investigated using a heater to provide the heating effect. The results showed that the population drops faster at a higher temperature; and there was no significant difference in the population pattern between the ultrasonic and heat treatments at a constant temperature of ~50℃. The overall results showed that ultrasonic treatment does not reduce the microorganism population in the cutting fluid, where temperature is a dominant factor.
