2000RPM Non-contact Inductive Transmission Ultrasonic Milling and Drilling
During ultrasonic drilling, the material is removed by micro-grinding or abrasive particle erosion.
The tool oscillates at a frequency of approximately 20 kHz by a piezoelectric sensor and an electric oscillator. The tool forces the abrasive grit to normally impact the work surface in the gap between the tool and the workpiece to machine the work surface.
