Lapping is a non-traditional machining technique that involves the use of abrasive compounds or slurries, and a precision-controlled
abrasive tool called a lapping plate. During the process, the workpiece is held against the rotating lapping plate, which removes material
from the surface in a carefully controlled manner. The combination of rotational motion and abrasive action results in the material being
removed uniformly, producing a high-precision, flat surface.
