The honing surface is cross-textured, which is conducive to the storage of lubricating oil and the maintenance of the oil film. It has a higher surface support rate (the ratio of the actual contact area between the hole and the shaft to the mating area between the two), which can withstand larger loads and wear resistance, thereby increasing the service life of the product. The honing speed is low, generally below 100m/min , which is only 1/3 to 1/100 of ordinary grinding , and the whetstone is in surface contact with the hole, so the average grinding pressure of each abrasive particle is small, and the vertical load of the abrasive particle It is only 1/50 to 1/100 of grinding , so that during honing, the heat generation of the workpiece is very small, and the surface of the workpiece has almost no thermal damage and deterioration layer, and the deformation is small. There is almost no sand embedded and extruded hard layer on the honing machined surface. During honing, a large amount of cutting fluid can be injected to wash away the fallen abrasive particles in time, and the machined surface can be fully cooled, so the workpiece has less heat and is not easy to burn, and the deformation layer is very thin, so that a higher surface can be obtained quality. Generally, high surface quality can be obtained by honing, the surface roughness Ra is 0.2 ~ 0.025um , and the depth of the metamorphic defect layer of the surface metal is very small ( 2.5 ~ 25um ).
