Grinding ceramics is unlike most other grinding operations, wherein a grinding wheel removes material by forming chips—albeit small ones. Grinding these superhard, brittle materials happens via a different mechanism. "You crack ceramic to death at the surface, and then you clear away that cracked material," said Jeffrey Badger, aka The Grinding Doc, who's based in …

A method for precision cylindrical grinding of hard brittle materials, such as ceramics or glass and composites comprising ceramics or glass, provides material removal rates as high as 19-380 cm 3 /min/cm.

A key process for the grinding-based manufacturing method for silicon wafers is wafer grinding (shown in Figure 2). For wafer grinding, the 65 rotation axis for the grinding wheel is offset by a distance of the wheel radius relative to the rotation axis of the wafer. During grinding, the wafer is held on a porous ceramic chuck by means of vacuum.
