Abstract:
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; a plurality of probe centering location finders secured within the respective cavities and having outer surfaces having in combination a diameter approximately equal to the start diameter of the work-piece; and a plurality of actuators which independently adjust the radial position of each of the location finders to properly center the skiving and roller burnishing tool as it is advanced through the work-piece, wherein the plurality of probe centering location finders each include a radially disposed threaded aperture and wherein the plurality of actuators each include an adjustment screw threadably engaged in the respective threaded aperture and in contact with the base of the respective cavity to adjust the radial disposition of the plurality of probe centering location finders, and wherein the leading end of the skiving and roller burnishing tool further includes a plurality of laterally disposed threaded apertures intersecting the respective cavities, wherein the plurality of probe centering location finders each have a cylindrical configuration having planar sector, and wherein the plurality of actuators include securing screws threadably engaged in the respective laterally disposed apertures and engaging the respective probe centering location finders at the planar sectors to prevent radial translation of said finders following radial adjustment thereof with the adjustment screw.
