Honing, lapping, and superfinishing are precision micro-finishing processes used when conventional material-removal operations (turning, milling, grinding) cannot achieve the required dimensional accuracy, surface finish, or surface integrity. Honing uses a bonded-abrasive tool with combined rotary and reciprocating motion to finish holes; lapping uses loose abrasive carried in a vehicle between a lap and workpiece with non-positively-driven relative motion; and superfinishing uses a bonded-abrasive stick with short, high-frequency oscillation at low speed and pressure to remove micro-irregularities without significant heat generation. This belongs to manufacturing processes / production engineering, specifically the sub-field of precision and micro-finishing operations that complete the surface-quality requirements left unmet by primary machining processes.
