Diamond Burnishing Tools

1. The Cogsdill Diamond Burnishing Tool is mounted in the tool post of the desired machine.

2. The diamond burnishing point is brought into contact with the workpiece at the centerline of the part and perpendicular to the surface being finished.

3. The tool is then fed into the workpiece an additional .002 or .003 inch (.05 or .08mm) to allow the diamond insert to become disengaged from the stop in the holder.

4. The spring, with its preload, forces the diamond against the workpiece.

5. The tool is then fed along the surface of the rotating workpiece to produce a mirror-like finish.

Replaceable diamond insert is polished and contoured for superior finishes and long tool life.
