Abstract (en)
[origin: WO0206007A1] A micro burnishing apparatus using ultrasonic vibration wherein a structure is contacted at a surface thereof by a ball of a burnishing head while the burnishing head is inserted into a horn, the horn being coupled to an ultrasonic oscillator for generating ultrasonic by oscillating high frequency received from a high frequency generator and the horn being pressurized by a spring, where the ball touches the structure and is vibrated to burnish the surface of the structure, such that surface hardness is increased with improved degree of surface roughness and sharp reduction of processing time.
