Mechanism of Effect of Ultrasonic Activated Coolant on Finished Surface Roughness(Grinding technology)

Abstract

The use of the ultrasonic activated coolant improves ground surface roughness compared with the use of ordinary coolant. From the evaluation of change in the working surface condition, it has been clarified that the ultrasonic activated coolant suppresses loading and wheel wear, and keeps the working surface condition well. Since the ultrasonic vibration increases the kinetic energy per width of the coolant, the activation makes the coolant easy to overcome the airflow following wheel rotation and to reach the grinding point. Furthermore, the flushing effect of the vibration acceleration prevents the deposition and weld of chips.
