★: 1st Recommendation ✩: 2nd Recommendation

  • Machining with coolant is recommended for Ni-base heat-resistant alloys and titanium alloys.
  • The bold-faced number indicates a center value of recommended cutting condition. Adjust the cutting speed and the feed rate within the above conditions according to the actual machining situation.
  • When finishing with LD type and FL type inserts, recommended feed rate for SOMT14 LD type: f=1.5(mm/rev) or less/for SOMT10 LD type: f=0.9(mm/rev) or less

for SOMT14 FL type: f=3.0(mm/rev) or less/for SOMT10 FL type: f=1.4(mm/rev) or less

  • For machining center equivalent to BT30, reduce feed rate to 25% or less of the recommended condition.
  • For slotting, internal coolant is recommended.
