Circular Knives

Shengao circular knives are crafted from premium materials to ensure exceptional durability and cutting performance in industrial applications:

• Tungsten Carbide: Superior wear resistance and hardness (HRA 88-95) for cutting abrasive materials and extended service life
• High-Speed Steel (HSS): Excellent heat resistance and durability for high-speed cutting applications in metalworking and general-purpose cutting
• Tool Steel Alloys (D2/SKD-11): High-carbon steel with chromium content for enhanced toughness and edge retention in various cutting environments
• Carbide-Tipped Designs: Combination of tough steel bodies with carbide edges for optimal performance and cost efficiency
• Specialty Coatings: TiN, TiCN, and Diamond-Like Carbon (DLC) coatings reduce friction, prevent material adhesion, and extend blade lifespan

Each material undergoes specialized heat treatment and precision engineering to achieve optimal hardness (HRC 58-65) while maintaining toughness for demanding industrial operations.

Selecting the appropriate circular knife depends on several key factors specific to your operational requirements:

1. Material Compatibility: Different materials (metals, plastics, wood, composites) require specific blade compositions and tooth geometries for optimal performance
2. Cutting Thickness: Thicker materials require knives with larger diameters and specialized tooth configurations
3. Production Requirements: High-speed applications need knives with optimized geometry and advanced coatings for heat resistance
4. Precision Needs: Fine-cut applications require knives with higher tooth counts and precision grinding for clean, accurate cuts
5. Machine Compatibility: Consider arbor size, maximum RPM, and power requirements of your equipment for perfect matching

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

Proper maintenance extends knife life and ensures optimal cutting performance:

• Regular Cleaning: Remove resin, pitch, and debris after each use to prevent buildup and maintain cutting efficiency using appropriate cleaning solutions
• Professional Sharpening: Maintain cutting edge sharpness through professional sharpening services using diamond wheels for carbide knives or appropriate abrasives for steel blades
• Proper Storage: Store knives in dry, controlled environments using protective covers to prevent damage and corrosion
• Performance Monitoring: Track cutting efficiency and inspect for wear patterns, chipping, or damage regularly to determine optimal maintenance intervals
• Rotation System: Rotate knives in multi-blade systems to ensure even wear and extended service life

Shengao offers professional sharpening services and provides detailed maintenance guidelines specifically designed for circular knives to maximize their lifespan and performance.
