Machining of ceramics [SubsTech]

Ultrasonic machining (UM) of ceramics is the machining method using the action of a slurry containing abrasive particles flowing between the workpiece and a tool vibrating at an ultrasonic frequency. The vibration frequency is 19 ~ 25 kHz. The amplitude of vibration 0.0005 - 0.002" (13 – 50 μm). During the operation the tool is pressed to the workpiece at a constant load.
