Ceramic Grinding: With the Right Setup, It's Not All That Difficult

This is where ceramic grinding comes in. Ceramics are quite hard after sintering. Some are several times harder than steel. It's only through grinding, lapping, and other abrasive processes that components achieve their final shapes. Doing so requires a very rigid and accurate machine tool. It also needs the right wheel.
