| Honing |
 |
Honing is a final finishing operation conducted on a surface, typically of an inside cylinder, such as of an automotive engine block. 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. Hones can be of the multiple pedal type (pictured below) or the brush type. Either type applies a slight, uniform pressure to a light abrasive that wipes over the entire surface.   |

Below are illustrated bad and good honed part geometries. Both pairs of figures show that a through hole design is always best for coolant flow, etc. The upper pair shows that a certain portion at the end of a blind hole is not completely honed. The lower pair shows that a right circular cylinder is the easiest to hone.
