Lead angle 0°/ 2° MFLN90 Face mills for heavy milling MFLN Tough 4-edge tangencial inserts provide high reliability on heavy milling at large depths of cut and high feed rates. 3 cutting edge angles (incl. MFLN45 and MFLN70) optimized for various machining applications. 1 Tough and reliable inserts for stable heavy milling 22 mm long inserts offer increased rigidity Tangentially mounted inserts provide 2 cutting Obtuse edge design edges on both sides Increases the cutting edge angle only at the tip to maintain both strength and sharpness Cross-section view of cutting edge MFLN Corner chamfer only available on MFLN90 Both general corner-R type and chamfered M corner type availablePrevents chattering and insert fracturing Conventional Convex cutting edge ridge Reduced impact forces when entering the workpiece Wide flat mounting surface Hold an insert firmly in heavy milling Tangentially mounted inserts increase rigidity Cutting forces when entering the workpiece (internal evaluation) MFLN90: Insert - chamfered corner type MFLN 6,000 Smoothly entering the workpiece Competitor A Competitor B 4,000 2,000 0 2.5 5.0 7.5 Cutting time (msec) Cutting conditions: Vc = 150 m/min, ap × ae = 5 × 75 mm, fz = 0.3 mm/t ø125 (1 insert), dry, workpiece: C50 M102 Milling Cutting force (N)
