<p>Apparatus and method for honing internal surfaces of a workpiece wherein at least one of the surfaces to be honed is a flat or non-circular aperture. Movable honing stones are mounted in a holding tool such that they can move back and forth transversely of the honing tool as the honing tool is moved longitudinally of the surface to be honed. A first series of honing stones is mounted in a series of parallel slots formed in the honing tool at an angle such that when the tool moves in a first longitudinal direction the honing stones will move to one side of the tool due to reaction forces and due to the angle at which the mounting slots are formed in the tool. A second series of honing stones is mounted in a second plurality of parallel slots formed in the tool such that they move transversely in a direction opposite to the first plurality of stones when the tool is moved in a first longitudinal direction. The result is that the first and second plurality of stones alternately move back and forth transversely with respect to the tool as the direction of travel of the tool changes resulting in a very precise and effective honing operation as well as providing that the tools are self-cleaning. In a preferable arrangement the first and second plurality of stones are mounted in slots which are at an angle of 45.degree. with the longitudinal axis of the tool.</p> |
