Ball Burnishing Tools – PTSC
Ball burnishing tools
Ball burnishing tool
Tailor made tools for smoothening and work hardening of spherical surfaces. The tool contains conically arranged rollers. It is positioned to the workpiece under a defined setting-angle. Both workpiece and tool must rotate. During this process the spherical surface is burnished „line by line“.
Advantages
- useable on lathe machines with driven tools
- very short machining time
- slim design
- fast return of investment
- low machining forces
