Variable diamond burnishing tools for external use are non-intrinsic tools for smoothening and work hardening of shafts and contours. Due to the swiveling diamond these tools are very versatile. ADVANTAGES - Simple to use - Compact design available for machines with limited tool space - Can be adapted to all materials by means of four spring elements (included in delivery) - Diamond radii from 0.4?5?mm available - Diamond indexed for multiple machining - Highest surface quality and hardening - Universally applicable - Ideal for contour machining - For hard machining and thin-walled workpieces - Tolerance compensation through spring-loaded design - Changeable diamond insert - Re-grinding of the diamond is possible - Cost-effective/low investment Diamond smoothing tools: for highest precision Diamond smoothing tools extend the range of applications for smoothing and strengthening surfaces of hardened materials up to over 60 HRC. A diamond glides over the surface to be smoothed. As soon as the yield point of the material is exceeded, the profile tips on the workpiece surface flow into the adjacent recesses in the µm range. Since the contact area between the workpiece and the diamond is smaller than in the case of machining by means of rollers, the plastic cold deformation can take place with less force. Diamond smoothing tools are used in areas where single and multi-roll tools reach their limits due to material properties or the geometry of the workpiece. Diamond smoothing tools are available for both internal and external machining.
