What Workpiece Types are Lapped?

Practically all workpieces comprising surfaces that need to be flat and parallel are lapped. The material is of no account: Anything can be lapped, from plastics to diamond itself, and the type of material affects only the rate of material removal and the surface quality obtained. Excellent results are achievable when the correct lapping agent and suitable lapping machine are used. Many production lines today are oriented towards lapping, and the lapping machine is incorporated in transfer sections (Figures 41 & 42). Machines are now commercially available for handling workpieces weighing from a few grammes up to a ton.
