Honing: Honing is a finishing operation performed on the inside of cylindrical shapes. Abrasive stones, sticks or brushes are arranged in a triangular shaped tool and fitted to the inside or bore of a cylinder. Honing is used for very slightly altering the surface, as in tightening dimensional tolerance, rather than removing material to substantially change the dimension.
