Burtoll Diamond Burnishing Tools are simple, efficient tools designed to produce mirror-like finishes on a wide range of fer rous and nonferrous part surfaces on most turning machines
Set up and cycle times are short, even for unskilled operators. In all cases,the replaceable diamond insert can be changed quickly; on some models without removing the tool holder from the machine.
Diamond Burnishing Tools are commonly used in industries such as aerospace, automotive, medical, and precision engineering—where surface integrity and accuracy are critical.
Ask for catalogueHow It Works?!
The Burroll Diamond Burnishing Tool is mounted in the tool post of the desired machine. The diamond burnishing point is brought into contact with the workpiece at the centerline of the part and perpendicular to the surface being finished. 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. The spring, with its preload, forces the diamond against the workpiece. The tool is then fed along the surface of the rotating workpiece to produce a mirrorlike finish.
As a recommended starting point the adjusting screw should be tightened (turn clockwise) until all clearance between the push rod and the spring is removed. Then tighten the screw another 1 to 2 turns which will compress the spr ing to provide the necessary preload to the diamond insert. This is the
