ELID technique grinding

Stable, efficient, and precise grinding of ceramic components has been achieved by mirror grinding using the ELID technique.

The wear of abrasive grains will produce an instability of the grinding performance for dressing technique, while it remains constant for ELID technique.

ELID grinding technique induces compressive surface stress of about 150-400 MPa, with a smaller peak than that outputted by a honing process of 600-800 MPa.

It can be seen that the wear rate of the grinding wheel covered with oxide film is very large, about 10 mm /mm. However, the grinding ratio value for the wheel with oxide film is larger than that of the wheel without oxide film. It can be concluded that ELID-grinding is an efficient technique whenever high productivity is required.
