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“.



  • useable on lathe machines with driven tools
  • very short machining time
  • slim design
  • fast return of investment
  • low machining forces
