Definition. Superfinishing is a process in which a rotating workpiece is finished by a relatively soft stone with fine abrasive oscillating parallel to the workpiece surface. The stone typically oscillates at an amplitude of 1–4 mm and a frequency of 10–50 Hz, and it contacts the workpiece at light pressure, typically 0.1–0.2 MPa.

The lapping process is more gentle than honing and removes much less surface material. Therefore, the workpiece should be as close as possible to final size — achieved, for example, through double-disk grinding — because lapping typically removes only 0.0005" to 0.005" (0.0127 mm to 0.127 mm) of material.
