(1) Two-Flute End Mills
Features: Low cutting resistance, smooth chip evacuation, suitable for high-speed machining.
Applications: Mainly used for machining soft materials such as aluminum alloys and plastics, commonly found in the 3C industry and mold roughing.
(2) Three-Flute End Mills
Features: Balanced cutting efficiency and stability, versatile.
Applications: Suitable for semi-finishing and finishing of materials like steel, stainless steel, and cast iron.
(3) Four-Flute End Mills
Features: High rigidity, excellent cutting efficiency, ideal for heavy cutting and high-precision machining.
Applications: Widely used for efficient machining of hard materials such as steel, cast iron, and titanium alloys.
(4) Multi-Flute End Mills (Six or More Flutes)
Features: Multiple flutes ensure smooth cutting and high surface finish.
Applications: Primarily used for finishing, suitable for workpieces requiring high surface quality, such as mold cavities and precision parts.
2. Classification by Groove Type
(1) Straight Flute End Mills
