Double-sided 6-edge insert MFWN • Economical double-sided 6-edge insert • Superior fracture resistance due to thick edge design • A vailable for a wide range of applications and now including PDL025 DLC coated insert grade for aluminum machining 1 Sharp cutting due to lower cutting forces • Low cutting force due to steep rake angle • Dynamic slant design reduces initial impact when cutting edge enters the workpiece A.R. Max. +13° Dynamic slant design Cutting force comparison (In-house evaluation) 4,000 17.3 % 3,500 DOWN 3,000 100 % 115 % Cutting force (N) 2,500 121 % 2,000 MFWN Competitor A Competitor B GM chipbreaker (Positive insert) (Negative insert) Cutting conditions: Vc = 180 m/min, ap × ae = 7 × 110 mm, fz = 0.2 mm/t Workpiece: C50, cutter dia. ø125 mm 2 Reduced chattering Resistant to chattering due to low cutting force design and applicable to long overhang Sound pressure level (spl) Surface roughness comparison (In-house evaluation) MFWN Competitor C Cutting noise comparison (In-house evaluation) 80 No chattering Chattering 60 50.4 % 40 DOWN 100 % 20 154 % 202 % 0 MFWN Competitor D Competitor E GM chipbreaker (Positive insert) (Negative insert) Cutting conditions: Vc = 200 m/min, ap × ae = 3 × 15 mm, fz = 0.1 mm/t Workpiece: C50, cutter dia. ø80 mm (7 Inserts) 1 350 mm (Overhang)
