Application processing examples
When grinding PZT (piezoelectric zirconate titanate), which is commonly used as piezoelectric material, surface roughness varies among die on the surface. This variation can be reduced by applying “In-feed and Creep feed Grinding”.
Reducing the surface roughness variation in PZT grinding leads to the stability in the following features.
Compared with in-feed grinding, creep-feed grinding is more effective as a measure to prevent surface
It is possible to reduce the surface roughness to about one fifth.
For details, refer to the below drawing.
A free-of-charge test cut is performed at an application lab to confirm whether achieving the customer's needs is possible.
