Machining the wheelset

1. Train wheel

1. RCMX... indexable insert

Rough turning

  • Tool holder: PSC100-DRGCN-X32
  • Indexable insert: RCMX 3209MOSN-R33 1494
  • Additional clamping via a special clamping claw with indexing system matching the geometries: -R33, -R63, -M23
    - Prevents vibrations & rotation of the indexable insert during machining

→ Fewer insert breakages
→ High process security
