The cutting process of honing is that the workpiece is fixed during honing. The honing head and the machine tool's spindle are floating and connected under a certain pressure through the relative movement of the honing head and the workpiece surface so that a very thin layer of metal is cut from the machining surface. During honing, the honing head has three movements, namely rotary motion, reciprocating motion and radial pressurizing motion perpendicular to the processing surface. The first two movements are the main movements of honing. Their synthesis makes the cutting trajectory of the abrasive grains on the stone on the surface of the hole intersect without reticulation, so it is easy to obtain a surface with a low surface coarseness. Radial pressurization is the feed motion of oilstone. The greater the pressure, the greater the feed.
