High precision diamond JC-DY2045R1.5 point outer surface roller burnishing tools
JC -DY Diamond head burnishing tool

Diamond head burnishing tool has wide application range and strong versatility. It can burnish the workpiece with the highest hardness of HRC60. It is also suitable for the processing of the workpiece with minimal diameter, complex outer diameter and thin wall.
Processing principle
It uses high strength and high precision diamond to burnish workpiece surface. With the applied pressure exceeding the yield point of the material, the surface of the part will be plastic deformed due to cold extrusion of the shallow material to achieve mirror surface finishing.
Processing advantage
1. One Tool can be used for various taper, circular arc and outer circle.
Outer surface burnishing |
Conical surface burnishing |
Spherical surface burnishing |
End surface burnishing |
2. The surface roughness of workpiece will be less than Ra0.1.
3. It can extend into the inner minimum 14mm hole.
4. Many point are available and long service life.
5. It can burnish the material whcih hardness up to HRC60 degrees.
6. the surface hardness of the workpiece will be increased to 15-30%.
7. The wear resistance of the workpiece will be increased by 15%.
8. Improve the fit of parts and corrosion resistance.
9. No special equipment, low cost.
