Abstract: A honing tool holder utilizes pressure of a through-the-spindle coolant delivery system for automatically feeding the honing elements or stones of an attached honing tool when in the bore of a work piece, and for automatically stopping the feeding when a particular condition such as a bore size, is reached, so as to enable use of an in-process adjustable feed honing tool in a machine tool, machining center, or the like, lacking a feed mechanism or system but including a coolant delivery system. The holder can also include apparatus to automatically prevent feed past a limit. Both the feed force and feed limit can be adjustable, at least the latter by simple movements of the tool holder by the machine tool.

Abstract: The tool includes a body which supports angularly spaced roughing hones and angularly spaced finishing hones for radially inward and outward movement between collapsed and expanded positions. Expansion of the roughing hones is effected by axially spaced ramps when a rod is moved linearly in one direction while expansion of the finishing hones is effected by additional axially spaced ramps when the rod is shifted linearly in the other direction. By turning an adjusting nut from the free end of the tool body, the axial spacing between the ramps of the roughing hones may be changed for purposes of adjusting the inclination of the roughing hones. A second adjusting nut coaxial with the first nut may also be turned from the free end of the tool body to change the axial spacing between the ramps of the finishing hones and thereby effect adjustment of the inclination of the finishing hones.
