An experimental study of ultrasonic vibration-assisted grinding
2012 2nd International Conference on Advances in Computational Tools for Engineering Applications (ACTEA), 2012Two-dimensional ultrasonically assisted grinding technique is proposed to achieve a high material removal rate and high surface quality simultaneously. In this technique, the work-piece is attached on the ultrasonic vibrator produced by bonding a PZT device on a metal elastic body, and the elliptic vibration is generated by the simultaneous creation of

Effects of Grinding Fluid Excited by Ultrasonic Vibration
Materials Science Forum, 2016Ultrasonic excited fluid has been researched for machining of hard-to-grind materials. Ultrasonic vibration is applied to grinding fluid by an ultrasonic oscillating comb-shape effecter with integrated nozzle. Grinding fluid discharges from a nozzle placed between the comb’s feet and passes through the vacant space between comb teeth.
