Lapping is the finest machining method that allows very high surface qual-

ities, form accuracies, and very close dimensional tolerances. Lapped surfaces

are flat-lustrous and are characterized by isotropic properties. The specific

surface structure of lapped surfaces offers an especially good basis for

polishing [1-3].
