Honing head for high-speed operation
 A honing head comprises a holder having a plurality of radial guide slots angularly spaced from each other and an axial hole, a rough-finishing cone shaft and a finishing cone shaft or a single cone shaft axially slidably received in the hole, and a plurality of rough-finishing and finishing honing stone supports alternately disposed in the guide slots for radial movement therein. The honing stone supports have axially spaced legs having inclined cam surfaces held in abutment with tapered portions of the cone shafts. The honing stone supports are connected to the cone shafts by connectors having one ends fixed to the honing stone supports and second ends slidably received in grooves defined in the cone shafts or the supports and having portions inclined with respect to the axes of the cone shafts in the same direction and at the same angle as the inclination of the tapered portions. Thus, axial movement of the cone shafts causes the honing stone supports to be forcibly displaced radially into or out of the guide slots. The holder includes reinforcement members mounted in the guide slots which members serve to give the holder a required degree of mechanical strength and rigidity for stabilizing the honing stone supports during honing operation and preventing a boring tool attached to the holder from being vibrated during boring operation.
