ABSTRACT:
The tool has a shank with a draw bolt threaded in an open recess in one end. A compression ring is mounted on the draw bolt and has an axially tapered outer peripheral surface. A burnishing ring is received about the draw bolt compression ring and axially engages the end of the tool shank. The burnishing ring has an outer diameter which is greater than the maximum outer diameter of the tool shank as well as being greater than the maximum outer diameter of the draw bolt. The burnishing ring has an inner diameter axially tapered surface which mates with the axially tapered outer peripheral surface of the compression ring. When the draw bolt is tightened it holds the compression ring tightly within the burnishing ring, thereby providing a mount for the burnishing ring. The burnishing ring has a precise desired outer diameter for burnishing a bore. The burnishing ring may be made of carbide or similar material and can be quickly removed and replaced as necessary due to wear or the requirement for a different burnishing diameter. Alternatively, the burnishing ring may be made of a material having a sufficiently high modulus so that the burnishing ring expands as the draw bolt is tightened and the compression ring is moved axially within the burnishing ring. The burnishing ring is expanded to the precise desired outer diameter for burnishing a bore, but is not expanded until it reaches the yield point. A jam nut may be provided on the draw bolt to lock the burnishing ring and the compression ring in position, the jam nut having a maximum outer diameter which is less than the maximum outer diameter of the burnishing ring.
