How Ultrasonic Machining Works? Working Principle & Advantages

Sep 02, 2021· 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.
