What is Honing?
Honing is final finishing operation conducted on a surface, typically of an inside cylinder (bore), for example automobile engine cylinder. Abrasive stones are used to remove minute amounts of material in order to tighten the tolerance on cylindricity. Honing is a surface finish operation, not a gross geometry-modifying operation. Honing Holders apply a slight, uniform, pressure using a number of abrasive sticks (Honing Sticks) that wipe over the entire surface to honed thus removing material from the surface.
Honing is the final process used in the machining cylinder bores, either during manufacture or in re-sizing (re-boring). Honing is used as a process to both remove the final amount of metal to get a cylinder bore to within the required size limits, and to put a surface on the cylinder bore which will give good life span, and aid lubrication and oil consumption characteristics in use.
Honing is not only carried out on cylinder bores for internal combustion engines but on compressors, hydraulics components and probably hundreds of other applications.
