Ultrasonic drilling is an unconventional loose abrasive processing process. Ultrasound is a sound wave with a frequency higher than 20,000 Hz. 

Ultrasonic can be generated using mechanical, electromagnetic and thermal energy sources. They can be produced from gases (including air), liquids and solids.

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.

The smaller the grit size, the smaller the momentum received from the tool. As the tool continues to move downward, the force acting on the larger coarse particles increases rapidly, so some coarse particles may break. Eventually, at the end of its stroke, the sand with a size greater than the minimum gap will penetrate the tool and the work surface to varying degrees.

1.Technology integration via R8 actuator system;

2.ULTRASONIC superimpositioning of the tool rotation with amplitudes up to > 10 µm;

3.Automatic frequency detection -adation, amplitude regulation and automatic feed adjustment;

4.Up to 50% reduced process forces due to ULTRASONIC allow: higher feeds, better surface finishes up to Ra < 0.2 µm, longer tool life.
