How Ultrasonic Machining Works? Working Principle & Advantages
In ultrasonic machining, a tool vibrating longitudinally at 20 kHz to 30 kHz with an amplitude between 0.01 mm to 0.06 mm is pressed onto the work surface with a light force.. As the tool vibrates with a specific frequency, an abrasive slurry, usually a mixture of abrasive grains and water of fixed ratio (20% – 30%), flows under pressure through the tool-workpiece interface.

Review on ultrasonic machining - ScienceDirect
In USM, high frequency electrical energy is converted into mechanical vibrations via a transducer/booster combination which are then transmitted through an energy focusing device, i.e. horn/tool assembly 1, 17, 18, 30, 32.This causes the tool to vibrate along its longitudinal axis at high frequency (usually ≥20 kHz) with an amplitude of 5–50 μm 16, 33, 34.

Ultrasonic horn - Wikipedia
An ultrasonic horn (also known as acoustic horn, sonotrode, acoustic waveguide, ultrasonic probe) is a tapering metal bar commonly used for augmenting the oscillation displacement amplitude provided by an ultrasonic transducer operating at the low end of the ultrasonic frequency spectrum (commonly between 15 and 100 kHz). The device is necessary because the amplitudes provided by the ...
