The lapping process is more gentle than honing and removes much less surface material. Therefore, the workpiece should be as close as possible to final size — achieved, for example, through double-disk grinding — because lapping typically removes only 0.0005" to 0.005" (0.0127 mm to 0.127 mm) of material.

Grinding is a thermally dominated process, meaning a high percentage of process heat initially enters the part before coolant quenches it. Unless the coolant is applied at the correct flow rate and pressure, and the proper input conditions are selected, this process can lead to undesirable rehardening burn, thermal softening and tensile residual stresses.

The speed of the plate is by far the most important factor to consider in machining lapping. Higher speeds are inductive to smoother surfaces but are also more likely to cause certain objects to vibrate. An optimal speed would keep the workpiece firm in place. The desired effect and surface texture determine the choice of abrasive particles.
