Although still relatively new in aluminium machining applications, Osawa says 4-flute geometry enables high feed rates and high stock removal. Completely lapped flutes and cutting edges combined with unequal pitch geometry allow the reduction of friction and vibration, thus aiding swarf evacuation even in case of heavy material removal.
According to Osawa, the positive cutting angle and unequal pitch help reduce shear stress, while the wiper profile allows mirror-like finishing. The HF ALU end-mill achieves feed up to 8,000 mm/min for slot processing and is suitable for both machining using at full DxD, as well as for shouldering.
