Rotary Cutters / Rotary Knives

Shengao rotary cutters are crafted from premium materials to ensure exceptional durability and cutting performance in demanding industrial applications:

• Tungsten Carbide: Superior hardness (HRA 88-95) and wear resistance for cutting abrasive materials including metals, composites, and technical fabrics, providing extended service life in high-volume operations
• High-Speed Steel (HSS): Excellent heat resistance and durability for high-speed cutting applications, maintaining sharpness in continuous operation with temperatures up to 600°C
• Tool Steel Alloys (D2, M2): High-carbon steel with chromium content providing optimal toughness and edge retention for various cutting environments and material thicknesses
• Specialized Coatings: TiN, TiCN, TiAlN, and Diamond-Like Carbon (DLC) coatings reduce friction, prevent material adhesion, resist corrosion, and enhance heat resistance for improved cutting efficiency

Each material undergoes specialized heat treatment and precision engineering to achieve optimal hardness (HRC 45-65) while maintaining toughness and structural integrity for industrial cutting operations.

Selecting the appropriate rotary cutter depends on several key factors specific to your operational requirements and material characteristics:

1. Material Type: Different materials (metals, plastics, composites, textiles) require specific cutter compositions, blade geometries, and coating technologies for optimal performance and clean cuts
2. Production Requirements: High-speed applications need cutters with optimized blade geometry (45mm, 60mm, or 70mm diameters) and advanced coatings for heat resistance and durability in continuous operation
3. Precision Needs: Fine-cut applications require cutters with higher precision grinding (tolerances ±0.0015mm) and appropriate blade sizes for clean, accurate cuts with minimal tear-out
4. Thickness Capacity: Thicker materials require cutters with larger diameters and specialized configurations (octagonal blades, reinforced structures) to handle increased cutting forces up to 25mm thickness
5. Machine Compatibility: Consider power requirements (170W-750W), maximum RPM (2400±10%), and arbor size specifications of your equipment for perfect matching and optimal performance

Our technical team provides customized recommendations based on your specific material characteristics, production volume, and performance expectations for optimal results in your industrial application.

Proper maintenance extends cutter life and ensures optimal cutting performance for industrial rotary cutters:

• Regular Cleaning: Remove resin, pitch, and debris after each use using appropriate cleaning solutions and techniques to prevent buildup and maintain cutting efficiency
• Professional Sharpening: Maintain cutting edge sharpness through professional sharpening services using diamond wheels for carbide blades or appropriate abrasives for steel blades, typically every 80-120 operating hours
• Proper Storage: Store cutters in dry, controlled environments (15-25°C, humidity below 50%) using protective covers and cases to prevent damage, corrosion, and blade deterioration
• Performance Monitoring: Track cutting efficiency and inspect for wear patterns, chipping, or damage regularly to determine optimal resharpening intervals and replacement needs
• Lubrication System: Utilize built-in lubricant storage systems and regular lubrication with appropriate oils to enhance smooth operation and prevent overheating during extended use

Shengao offers professional sharpening services and provides detailed maintenance guidelines specifically designed for rotary cutters to maximize their lifespan and maintain peak cutting performance.
