Special Coated Blades

Shengao special coated blades are crafted from premium materials and advanced coatings to ensure extreme durability and performance in demanding industrial environments:

• High-Speed Steel (M2, M35): Ideal for high-temperature applications with excellent red hardness and wear resistance, often used as substrate for coatings.
• Tungsten Carbide Composites: Superior hardness (HRA 90-92) for cutting abrasive materials like metals and composites, enhanced with coatings for extended life.
• Tool Steel Alloys (SKD11, CR12MOV): Provides high toughness and impact resistance, suitable for heavy-duty cutting operations.
• Advanced Coatings (TiN, TiCN, AlCrN): Titanium Nitride (TiN) reduces friction and prevents material adhesion, Titanium Carbonitride (TiCN) offers enhanced hardness, and Aluminum Chromium Nitride (AlCrN) provides superior heat resistance and corrosion protection for harsh environments.

Each material undergoes specialized heat treatment (including vacuum hardening and cryogenic processing) to achieve optimal hardness (HRC 60-65) while maintaining structural integrity, ensuring consistent performance in high-speed and abrasive applications.

Selecting the appropriate coated blade depends on several key factors to ensure optimal performance and efficiency:

1. Material Type: Different materials (e.g., plastics, metals, composites, textiles) require specific blade compositions and coatings—TiN for non-stick properties, TiCN for hardness, AlCrN for high-temperature resistance.
2. Cutting Environment: Consider operational conditions such as humidity, temperature, and exposure to chemicals; choose coatings like AlCrN for corrosion protection in wet or chemical-rich environments.
3. Production Speed and Thickness: High-speed applications need blades with specialized coatings to reduce friction and heat buildup, while thicker materials may require larger diameters and enhanced wear resistance.
4. Application Requirements: Factors like cut quality, blade longevity, and maintenance intervals; for fine cuts, opt for blades with more teeth and precision-ground edges with coatings that minimize material adhesion.

Our technical team provides customized recommendations based on your machine specifications, material characteristics, and operational goals to ensure the best blade solution.

Proper maintenance extends the service life of coated blades and ensures consistent cutting performance:

• Regular Cleaning: Remove residue, dust, and debris after each use to prevent coating degradation and material buildup, especially after processing abrasive materials like metals or composites.
• Periodic Sharpening: Maintain razor-sharp edges through professional sharpening services every 100-200 operating hours; coated blades can be resharpened multiple times due to their durable substrate and coatings.
• Proper Storage: Store blades in a dry, clean environment with protective coatings to avoid moisture-induced corrosion; vertical storage is recommended to prevent edge chipping and damage.
• Coating Inspection: Regularly check for signs of coating wear, such as discoloration or peeling, and consider recoating services to restore performance and extend blade life.

Shengao offers maintenance services including sharpening and recoating, along with detailed guides to minimize downtime and operational costs.
