Lapping is an advanced surface flattening process that achieves flatness tolerances of to 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.

Post plating grinding and buffing may improve the visual aesthetic. These coatings are more expensive (see below table) compared to boron and phosphor electroless nickel plating by themselves. Some examples of the types of particles are aluminum oxide, silicon carbide, tungsten carbide, and in rare cases diamonds or other mined minerals.

2. The specific process of grinding and polishing of sapphire wafers. 1. Rough grinding: high hardness micro powder with particle size of 2643um is used as abrasive, which is mixed with deionized water, dispersant and suspending agent to form coarse grinding fluid. The abrasive accounts for 15~30%. Then put them into the grinder for grinding. 2.
