What is Lapping? Lapping QA
The principle of lapping is simple and based on the cutting power of either a free abrasive grain in a carrier or a fixed abrasive particle within a composite lapping plate matrix. A lapping plate on which a lapping slurry has been applied moves under the workpiece surface whilst the workpiece rotates on the lapping plate.
