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

Abstract

The use ofthe ultrasonic activated coolant improves ground surface roughness compared with the use of erdinary coolant.From theevaluation ofchange in theworking surface condition, ithas been clarified that the ultrasonic aetivated coolant suppresses loading and whee] wear, and keeps the working surface condition well.Since the uItrasonic yibration increases the kinetic energy per width ofthe coolant, the activation makes the coolant easy to overcome the airflow fbllowing wheel rotation and to reach the grinding point. Furthermore, the fiushing effect ofthe vibration acceleration prevents the deposition and weld of chips.
