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.
