* For MSR, cutting speed should be carefully adjusted depending on the length of toolholder protruding from the end of machine spindle. ★: 1st Recommendation

  • When the overhang length of toolholder is small, ➮ set the cutting speed to slightly higher than the recommended cutting conditions. ✩ : 2nd Recommendation
  • When the overhang length of toolholder is long, ➮ set the cutting speed to slightly lower than the recommended cutting conditions.
