Product Description
High-Performance SL-Shaped Carbide Rotary Burrs for Aluminium Cutting
Our SL-shaped carbide rotary burrs feature a specialized spherical long neck design, combining the reach of extended shank tools with the precision of ball-nose cutters. These burrs are engineered specifically for deep cavity machining, 3D contouring, and hard-to-reach areas in aluminium components.
Key Product Advantages
- Extended Reach Design - Long neck profile enables deep pocket machining (up to 5:1 L/D ratio)
- Anti-Galling Geometry - Proprietary flute pattern prevents aluminium adhesion
- Premium Materials - K50 micro-grain carbide with 42CrMoV alloy steel shank
- Automated Silver Brazing - Computer-controlled process ensures 100% joint integrity
- Aerospace-Grade Precision - Ground to tolerances of ±0.003mm for vibration-free operation
Technical Specifications & Materials
1. Cutting Head Composition
- Carbide Grade: K50 (94% WC, 6% Co)
- Hardness: HRA 93.5±0.3
- Grain Size: 0.3-0.5μm ultra-fine grain structure
- Brazing Technology: Fully automated silver brazing (56% Ag content)
2. Shank Specifications
- Material: 42CrMoV chrome-moly-vanadium alloy steel
- Heat Treatment: Vacuum hardened to HRC 60-62
- Runout: <0.002mm (DIN 8032 Class AA standard)
Advanced Manufacturing Process
- Material Preparation
