Lapping is a machining process in which two surfaces are rubbed together with an abrasive between them, by hand movement or using a machine. Lapping machine. Lapping often follows other subtractive processes with more aggressive material removal as a first step, such as milling and/or grinding. Lapping can take two forms.

Furthermore, in the lapping process, the upper lapping plate applies the load and remains stationary, while the lower lapping plate rotates, which is different from the first method. The simplest trajectory is an eccentric circle, and hence Kang et al. employed an eccentric lapping machine for lapping silicon nitride balls [84, 85].

Having two lapping machines set up with one as "lapping" and the other as "polishing" might be the usual situation for production. As Forrest said the "so called" conditioner is the heavy circular piece that is positioned inside and outside as required to keep the lap flat. The manufacturers have literature on what is important in technique.

The main difference between lapping and stropping is the type of tool used. Lapping requires a flat surface, such as a lapping plate, to create a consistent angle and remove material evenly. Stropping, on the other hand, requires a flexible surface, such as a leather or fabric strop, to contour to the blade's edge and polish it effectively.
