Nine9 i-center runs well both in high and low spindle speed machines
The “i-center” indexable center drill has good performance for drilling center holes at high spindle speed and feed rate. In order to covering the whole market, we should not forget there are still a lot of turning machines and special purpose machines have only low spindle speed. Here we are pleased to inform you that “i-center” is also possible to drill at low spindle speed without any problem!
Machine: TAKISAWA EX-108
material: S45C (JIS G 4051)
Insert: I9MT12T2B0315
Result:
Running well in different machine conditions. Cutting steadily without vibration. Lower feed rate is required when the spindle speed is low as well as the cutting chip is longer and the surface is a little rougher.
Tool life is expected and machining time is dramatically shortened than HSS drill.
