ID (Inside Diamter) grinding is performed on tubular parts (with inside diameter) that are usually held in a collet or chuck. The grinding wheel is smaller than the hole to be ground and turns at very high speed to maintain the proper surface speed (compare the large wheel and small work piece of OD grinding on previous page).
The image on the left shows a typical small hole being ground by an even smaller mounted grinding wheel like one of those shown below
As with OD grinding the grinding wheel and the part need to be moving in opposite direction at the point of contact. Therefore this ID part will turn clockwise and the ID wheel will turn counterclockwise.
