Centerless grinding silicon nitride

Centerless grinding silicon nitride

Centerless grinding silicon nitride

Anyone have any experience centerless grinding silicon nitride? Would like to run some screening tests for
either infeed or thrufeed centerless, but don't have a feel for infeed/thrufeed rates. The material is a high
tensile strength silicon nitride (~1000 MPa characteristic strength).

RE: Centerless grinding silicon nitride


Just curious, Did you ever get a response to this message which you posted in 1999?   I can possibly help on the grinding of Silicon-Nitride as I have been involved in the centerless grinding of WC and PCD with Diamond grinding wheels as well as centerless grinding of many Steel workpieces with CBN grinding wheels, (Resin and Vitrified).

Would need more background on the parts, size, wall thickness if applicable, etc.,  to give any additional thought.  Also, you can call me to discuss if interested.
