Advantages and Disadvantages of Ultrasonic Machining

Advantages:

§  Hard material can be easily machined by this method.

§  No heat generated in work so there is no problem of work hardening or change in structure of work piece.

§  Non-conductive metals or non-metals, which cannot be machined by ECM of EDM can be machined by it.

§  It does not form chips of significant size.

 

Disadvantages:

§  It is quite slower than other mechanical process.

§  Tool wear is high because abrasive particle affect both work-piece and tool.

§  It can machine only hard material. Ductile metal cannot be machine by this method.

§  It cannot used to drill deep hole.
