摘要
A device for honing blind bores in parts, a blind bore including a cylindrical bore open at one end and closed adjacent to the opposite end including a honing mandrel for mounting on a honing machine that produces rotation thereof, the mandrel having a cylindrical honing portion adjacent one end which portion and the adjacent portion of the mandrel have spaced axially extending slot therethrough to enable the honing portion of the mandrel to expand and contract in size, the honing portion having a portion adjacent to the end thereof which is somewhat larger than the rest of the honing portion when the honing portion is expanded for honing in the blind hole, the end portions of the mandrel between the spaced slots being elastically expandable from a retracted position which is less than the diameter of the surface to be honed to enable insertion therein to a more expanded condition wherein the diameter of the honing portion at the largest point is the diameter at which the mandrel will hone the blind hole. The present invention also includes a method for programming the operation of the device to produce the desired honing operations when honing blind holes.
