DoTriple-Mill – Turbine Casing for Plant Chimney – AH3135


Eliminated Chattering
- The component is not rigid due to hollow structure, so the competitor’s high feed cutter had chattering by its big thrust force. DoTriple-Mill could machine the component without chattering due to its low thrust force.

High performance
- Due to a limited spindle power, the customer had to use the competitor’s cutter at an un-optimized parameter setting. In the same parameter setting, however, DoTriple-Mill improved M.R.R. by 41% vs competition due to its light cutting design.
