ULTRASONIC MACHINING (Impact Grinding)*

Abstract

Ultrasonic machining or impact grinding is the use of ultrasonically induced vibrations delivered to a designed tool combined with an abrasive slurry, to produce accurate cavities of regular and odd shapes in hard brittle materials such as: fused quartz, glass, crystal, ceramic, carbides and various metals. Ultrasonic machining is a non-thermal, non-chemical, non-electrical process, and creates no change in the metallurgical, chemical or physical properties of the substrate.
