Impact Properties of the Ultrasonic Vibrating Grinding Wheel
Journal of the Japan Society of Precision Engineering, 1975 Thispaperdescribes somespecial impact properties of the grinding wheel which vibrates longitudinally in the frequency f= 28 kHz and the amplitude a = 0-6 μm. The vibration tensile stress σv is added to the nodal point of the vibrating wheel as the initial stress. The impact property of this vibrating wheel is examined by the Izod impact method.

Effect of Ultrasonic Vibration in Micro-Route Grinding.
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 1994 The micro-route grinding system was developed for efficient micro-cutoff and micro-slotting of fine ceramics. However, because of the use of a very thin electroplated diamond quill, it has several problems in the machining performance : elastic deflection and fracture of the quill, and chipping and large cutoff-surface roughness.
