Circular Shear Blades

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

• Tungsten Carbide: Superior hardness (HRA 88-95) and exceptional wear resistance for cutting abrasive materials including hardened steels, composites, and technical fabrics, providing extended service life in high-volume operations
• High-Speed Steel (HSS): Excellent heat resistance and durability (HRC 60-67) for high-speed shearing 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 (HRC 54-61) and edge retention for various cutting environments and material thicknesses
• Powder Metallurgy Steels: Superior wear resistance and toughness compared to conventional tool steels, extending blade life especially when processing demanding or abrasive materials
• 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 metal shearing operations.

Selecting the appropriate circular shear blade depends on several key factors specific to your operational requirements and material characteristics:

1. Material Type: Different materials (metals, plastics, composites, textiles) require specific blade compositions and edge geometries for optimal performance - choose HSS for softer metals, D2 alloy for hard metals/stainless steel, and carbide for most abrasive materials
2. Production Requirements: High-speed applications need blades with optimized geometry and advanced coatings for heat resistance and durability in continuous operation at speeds up to 2,000 meters/minute
3. Precision Needs: Fine-cut applications require blades with higher precision grinding (tolerances ±0.0015mm) and appropriate blade sizes for clean, accurate cuts with minimal burr formation
4. Thickness Capacity: Thicker materials require blades with larger diameters and specialized configurations to handle increased cutting forces up to 25mm thickness
5. Machine Compatibility: Consider arbor size, maximum RPM, power requirements, and mounting mechanisms 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 metal cutting application.

Proper maintenance extends blade life and ensures optimal cutting performance for circular shear blades:

• Regular Cleaning: Remove resin, pitch, and debris after each use using appropriate cleaning solutions (neutral or weakly alkaline) and techniques to prevent buildup and maintain cutting efficiency - clean after disassembly when equipment is cool
• 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 or when cutting quality decreases
• Proper Storage: Store blades vertically in dry, controlled environments (15-25°C, humidity below 50%) using protective covers and proper holders to prevent damage, corrosion, and blade deterioration
• Lubrication System: Lubricate moving parts every 100 hours of operation using appropriate machine oils to reduce friction and prevent overheating during extended use
• Performance Monitoring: Track cutting efficiency and inspect for wear patterns, chipping, or damage regularly using vibration monitoring and visual inspection to determine optimal maintenance intervals

Shengao offers professional sharpening services and provides detailed maintenance guidelines specifically designed for circular shear blades to maximize their lifespan (up to 3x longer) and maintain peak cutting performance.
