Competitor ACompetitor B

Chip evacuation rate = 68cc/min (Negative cutter) 1 pc/edge

(Positive cutter) (Vertical inserts) Competitor A proceeded machining under low cutting conditions, as the workpiece Despite instability with the long overhang of the workpiece, MFWN doubled tool life, was slipping because of the unstable chucking. improving the efficiency by 150%.

With MFWN, stable machining was possible at higher cutting conditions.
