Description
High-Performance SF-Shaped Carbide Rotary Burrs for Aluminium Cutting
Precision engineered for superior aluminium machining, our SF-shaped carbide rotary burrs combine aggressive cutting with finishing capability, making them ideal for complex contouring and edge blending in aluminium workpieces.
Key Product Advantages
  • Dual-Purpose Design - Flame shape enables both roughing and finishing in one tool
  • Anti-Clog Geometry - Proprietary flute pattern prevents aluminium adhesion
  • Premium Materials - K40 micro-grain carbide with SCM435 alloy steel shank
  • Swiss Precision - Ground to tolerances of ±0.005mm for perfect balance
  • Versatile Application - Perfect for aerospace components, automotive molds, and precision engineering
Technical Specifications & Materials
1. Cutting Head Composition
  • Carbide Grade: K40 (93.5% WC, 6.5% Co)
  • Hardness: HRA 93±0.3
  • Grain Size: 0.4-0.6μm micro-grain structure
  • Coating Options: TiCN (Standard), ZrN (Premium)
2. Shank Specifications
  • Material: SCM435 chromium-molybdenum alloy steel
  • Heat Treatment: Vacuum hardened to HRC 60-62
  • Runout: <0.003mm for vibration-free operation
Advanced Manufacturing Process
  1. Material Selection
    • Only certified K40 carbide blanks from leading German suppliers
    • Traceable SCM435 steel with full material certificates
  2. Precision Machining
    • 6-axis CNC grinding with Diamond wheel technology
    • Micro-geometry optimization for aluminium-specific cutting
  3. Quality Assurance
    • 100% hardness testing (Rockwell & Vickers)
    • Digital microscopy inspection of cutting edges
    • Dynamic balancing to ISO 1940-1 G2.5 standard
  4. Surface Treatment
    • Electrolytic polishing for ultra-smooth finish
    • Anti-corrosion packaging with VCI protection
