Thermal effects of ultrasonically excited grinding fluid

In this study, to reveal reason of improvements by ultrasonic excited fluid, the amount of grinding fluid is measured. The amount is increased by the ultrasonic vibrations in case of fluid supply is small and the grinding wheel speed is higher. Moreover, the temperature at the grinding point is measured by constructing a thermocouple, it was confirmed that the grinding heat is reduced by using the ultrasonic excited fluid. And the effect of removing a grinding heat is due to the effect of the grinding fluid volume increased to grinding point. And, longer chip obtained with ultrasonic excited fluid compared with ordinary fluid. It shows suppression of wear of the abrasive grains with ultrasonic excited flui
