4 Flutes Endmill Taper Ball-Nose Milling Cutter For Non-Ferrous Metals

Introduction:

A 4-flute tapered ball-nose end mill is a precision solid carbide cutting tool engineered for 3D contouring, profiling, and finishing in soft, non-ferrous materials. The tapered design (reduced shank diameter) enhances rigidity for deep-cavity machining, while the ball-nose tip enables smooth, curved surface finishes.

Features:

• • Material: High-grade carbide with optimized hardness and toughness for non-ferrous metals.

• • Geometry:

    • Tapered body (e.g., 1°–5° per side) for improved reach and reduced deflection in deep pockets.

    • Ball-nose tip (R = 1/2 diameter) for intricate 3D shapes and fillets.

• • Flute Design:

    • 4 flutes – Balances chip evacuation and cutting efficiency in softer materials.

    • High helix angle (35°–45°) for shearing cuts and smooth finishes.

• • Coating: AlTiN, ZrN, or uncoated – Reduces built-up edge (BUE) in gummy materials like aluminum.

• • Edge Prep: Polished flutes to minimize material adhesion.

Typical Applications:

• • • Primary Use:

      • 3D sculpting (mold/die cavities).

      • Precision finishing of aluminum alloys, brass, copper, and plastics.

• • • Industries: Aerospace (blades, impellers), automotive (prototyping), jewelry, and signage.

• • • Machines: CNC milling centers, high-speed machining (HSM) setups.

Advantages:

✔ Smooth Finishes: Ball-nose eliminates stair-stepping on curved surfaces.

✔ Reduced Vibration: Tapered design enhances stability in deep cuts.

✔ Chip Clearance: 4 flutes optimize chip flow in non-ferrous materials.

✔ Wear Resistance: Carbide + coatings extend tool life in abrasive plastics/composites.

Technical Specifications (Example)

• • Diameter Range: 3mm–12mm (ball-nose radius: 1.5mm–6mm).

  • Taper Angle: 3° (common for balance of strength and reach).

  • Cutting Length: 15mm–50mm (depends on diameter).

  • Shank Type: Straight or Weldon flat for secure gripping.

  • Speed/Feed (Aluminum 6061):

    • RPM: 10,000–20,000 (for 6mm tool).

    • Feed Rate: 1,500–3,000 mm/min.

    • DoC: 0.1–0.5× diameter.
