End Mills: Precision Tools for CNC Machining and Beyond

Technical Specifications of End Mills

Shanghai Easydrill’s end mills are engineered for durability and precision. Key features include:

• Material:
  • Carbide: For high-speed machining and hardness (HRC 55+).
  • High-Speed Steel (HSS): Cost-effective for general-purpose milling.
  • Cobalt-Enhanced HSS (HSS-E): Improved heat resistance for tough alloys.
• Coatings:
  • TiN (Titanium Nitride): General-purpose coating for reduced wear.
  • TiAlN (Titanium Aluminum Nitride): High-temperature resistance (up to 900°C).
  • AlCrN (Aluminum Chromium Nitride): Ideal for non-ferrous materials like aluminum.
• Flute Types:
  • 2-Flute: Optimal chip evacuation in soft materials (e.g., aluminum).
  • 4-Flute: Balanced strength and finish for steel and harder metals.
  • 6+ Flutes: High-precision finishing in aerospace alloys.
• Diameter Range: 1mm to 25mm, catering to micro-detailing and heavy-duty milling.
• Helix Angles:
  • 30°–35°: For hard metals (e.g., titanium).
  • 45°–55°: For soft materials and efficient chip removal.
• Shank Types: Straight, Weldon, or BT/HSK for CNC machine compatibility.
• Speed Recommendations:
  • Aluminum: 500–1,500 RPM
  • Steel: 200–400 RPM
  • Stainless Steel: 150–300 RPM
• Compatible Materials: Metals (steel, aluminum, titanium), plastics, composites, and wood.

Applications of End Mills

End mills are versatile across industries:

1. CNC Machining: Create intricate parts for automotive, aerospace, and electronics.
2. Mold Making: Sculpt detailed cavities in injection molds with ball-nose end mills.
3. Aerospace: Machine lightweight alloys like titanium and Inconel for engine components.
4. Automotive: Mill engine blocks, transmission parts, and custom fittings.
5. Woodworking: Craft decorative engravings and joinery with specialized end mills.
6. Medical Devices: Produce precision surgical tools and implants from biocompatible materials.

Advantages of Using End Mills

End mills outperform conventional tools with these benefits:

• Precision: Achieve tight tolerances (±0.01mm) for complex geometries.
• Versatility: Cut in any direction (axial, radial, or contouring).
• Efficiency: High material removal rates (MRR) reduce machining time.
• Durability: Carbide and advanced coatings extend tool life by 3–5x.
• Surface Finish: Produce mirror-like finishes with minimal post-processing.
• Adaptability: Available in square, ball-nose, and corner-radius designs for diverse tasks.
