Most lapping is done with a tooling plate or wheel (the lap) and fine-grained loose abrasive. It is impossible to make exact comparisons between all the different abrasives because different standards are used for average, minimum and maximum size, the percentage allowed outside those limits, and the distribution of sizes within those limits, but this list is the closest comparison available since all entries are compared to microns by. In engineering the main difference between lapping and similar methods, such as grinding, is that instead of having fixed abrasives like a grinding wheel, in lapping the abrasives are suspended in a liquid, known as a slurry. The combination of very fine abrasive particles in a chemically aggressive liquid provides a chemical-mechanical polishing action.
