Skiving and roller burnishing tool

Apparatus for finishing the cylindrical interior of a hollow work-piece, comprising:

• a rotatable skiving and roller burnishing tool adapted to advance through the cylindrical interior of the work-piece, said tool having a forward skiving section including a knife holding portion adapted to hold a skiving knife to skive the interior of the hollow work-piece from a start diameter to a larger, finish diameter, and a rearward roller burnishing section, the skiving section having a plurality of radially opening cavities disposed circumferentially about said skiving section in front of the location of the knife and a plurality of axially disposed threaded apertures intersecting the respective cavities;
• a plurality of probe centering location finders located within the respective cavities, each said finder having a radially disposed threaded aperture;
• a plurality of adjustment screws threadably engaged within the respective radially disposed apertures and bearing against the base of the respective cavities to establish the radial position of the respective probe centering location finders;
• and
• a plurality of securing screws disposed in the respective axially disposed threaded apertures to secure the radial position of the respective finders established by the adjustment screws,
• wherein the knife holding portion of the skiving section has a polygonal aperture having a plurality of inwardly directed roller bearings to allow the knife to move radially within the aperture.

Apparatus for finishing the cylindrical interior of a hollow work-piece, using a pair of oppositely disposed knife blades, said apparatus comprising:

• a rotatable skiving and roller burnishing tool adapted to advance through the cylindrical interior of the work-piece, said tool having a forward skiving section and a rearward roller burnishing section, the skiving section having a knife holding portion which includes a polygonal aperture extending radially through the knife holding portion:
• a plurality of roller bearings disposed on the inner surfaces of the polygonal aperture;
• and
• a polygonal knife holder disposed within and conformed to the polygonal aperture, so that the knife holder and the oppositely disposed knife blades attached thereto float axially within the knife holding portion of the skiving and roller burnishing tool on the roller bearings.
