What are the benefits of lapping compared to grinding?

28.07.2016A grinding process can cause high levels of stress on delicate materials as the grinding medium tears at the surface of the material, often generating a lot of heat and potentially leaving an uneven surface behind. The damage caused during grinding will also propogate through the material, often producing considerable sub-surface damage.
