0.6μm 4 Flutes End Mill Taper Ball Nose Milling Cutter Customized For Non-Ferrous Metals

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

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.

• 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.

• 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

• ✔ 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

• 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
