2 Inherits previous MFWN series design elements with fracture-resistant inserts and low cutting forces 1 Low cutting force and high chatter resistance Steep rake angle minimizes cutting forces Dynamic slant design reduces initial impact when entering the workpiece A.R. Max 11° Dynamic slant design 2 Superior fracture resistance with thick edge design Stable clamping strength with unique insert face design Cutting edge thickness: 5.2 mm (3.1 mm at the thinnest point) Optimized seating surface Fracture resistance comparison (Internal evaluation) *Not recommended for fz = 0.4 mm/t and above fz = 0.3 mm/t fz = 0.4 mm/t fz = 0.5 mm/t fz = 0.6 mm/t MFWN mini Further machining possible Competitor A Fracture Competitor B Fracture 0 2,000 4,000 6,000 Number of impacts (times) Cutting conditions: Vc = 120 m/min, ap x ae = 1.5 x 30 mm, dry Cutting dia. ø63, workpiece: Mold steel 37 ~ 43 HRC Cutting force (N) Cutting force comparison (internal evaluation) 1,200 1,000 800 600 400 200 0 MFWN Competitor A Competitor B Mini Cutting conditions: Vc = 150 m/min, fz = 0.15 mm/t, ap x ae = 1.5 x 35 mm, Dry Cutting Dia. ø63; workpiece: 42CrMo4 3 Neutral inserts for various uses Symmetrical side and bottom cutting edges provide a wide range of machining applications Can be used for plunging applications ae Side edge Bottom edge Left-handed toolholders are also available (custom order) 2
