Solid End Mill High feed rate, High efficiency FK/4MFR Innovative design for high efficiency stable milling Varied interval flute design / Variable lead Superior anti vibration performance due to Kyocera's unique varied interval flute design / variable lead Varied interval flute design Cutting force varies due to varied flute width, which prevents periodical vibration during milling. a p Variable Lead Every flute has its optimum Helix Angle (Lead Angle 9), which enables excellent anti vibration effect. Prevents chattering, and superior surface finish. Helix Angle :91=42°, 92=44° Variable Lead: Prevents chattering Workpiece Material End Mill Dia.

Excellent surface finish. (Internal evaluation) Special Flute Design a Stable Chip Evacuation Wide Chip Pocket Wide Chip Pocket Effects: Excellent chip evacuation at high feed rate machining. due to New Special Flute Design High rigidity due to increased core diameter Core diameter improves the rigidity, preventing vibration and inclination of tool during machining. o onventional End Mill 4MFK 4MFR SCM440 SCM415H Case Studies S45C Automotive parts n=3,500min'1 (Vc=77m/min) apxae=5x7mm Vf=1,000mm/min (fz=0.071mm/t) Wet 4MFK070-160 255 pcs i Competitor Coated Carbide C ()50 pcs Competitor Coated Carbide C 7-4 flutes n=2,000min-1 (Vc=44m/min) apxae=5x7mm Vf=150mm/min (fz=0.019mm/t) Wet 4MFK showed 5 times longer tool life than Competitor C. Compared to Competitor C, 4MFK increased the feed rate by 6.6 times. No vibration occurred. Stable machining.
