Notes:
  1. Always use caution and best judgement when applying updated speeds/feeds.
  2. Each individual application is different than the next. Rigidity of workpiece, tool holders, etc. may contribute to optimal feed rates.
  3. Nachi America assumes no liability for any results due to application of these speeds/feeds.
