In the wire lapping procedure, a lapping medium of grits (commonly SiC) and medium (commonly oil or glycol) is sprayed on a non-coated wire [KLOC09, p. 386]. Because of the high costs and expensive disposal of the slurry, researchers have developed strategies for slurry refreshment and recycling [KLOC09, p. 387].
The inner diameter saw, also called inside hole saw or ID-saw, consists of a rotating steel blade, whose inner diameter is electroplated with diamond grits (Fig. 4.9 right) [KLOC09, p. 387]. The steel blade is clamped at its outer diameter and either the saw blade or the workpiece are moved radially.
