Precision Lapping | Precise Lapping | Lapping Process

Lapping is an advanced surface flattening process that achieves flatness tolerances of 0.0005 to 0.00002 inches. The pressure on the parts and the process duration can be finely tuned to accommodate the part material and the final finish required. Under perfect conditions, parts can be lapped to within 10 to 20 millionths of an inch of flatness.
