Abstract
A honing tool assembly adapted to be chucked in a honing machine for reciprocation and rotation, the assembly comprising a diamond-plated tool for honing cylindrical bores in a workpiece, the diamond-plated tool having a spiral pattern on a cylindrical outer surface, a central bore in the tool adapted to receive a tapered rod engageable with a tapered surface on the central tool opening, the tool being provided with a longitudinal slot that allows the outside diameter of the tool to expand as a force is applied to the tapered rod whereby stock is removed from bore walls of the workpiece with precision roundness and concentricity.
Claims8
A honing tool assembly for precision machining a cylindrical bore in a workpiece comprising a sleeve, the sleeve having a cylindrical outer surface and an axis of rotation, an opening in the sleeve, the sleeve opening having a tapered wall and an axis coinciding with the axis of rotation;
- a mandrel extending through the sleeve opening, a tapered external surface on the mandrel engaging the tapered wall of the sleeve opening along the length of the opening;
- and
- diamond granule plating on the outer surface of the sleeve;
- the sleeve and the diamond granule plating having a longitudinal slot extending along the length of the sleeve, whereby the effective outside diameter of the sleeve is expanded as a longitudinal force is applied to the mandrel.
